How is the site changing?
Get a detailed summary of every change and update here.
One of the major advantages of web based resources must be that they remain dynamic. Whilst I hope there is already a significant amount of very useful resources on this site, the advantage to subscribers should be that they are being constantly updated and added to so that the resource gets better and better and moves with the times. The 'What's New?' section on the homepage gives notification of new pages, but updates and changes to the site will come in many different shapes and sizes. There will be new worksheets and activity sheets added to pages and corrections made to existing resources. I will count on help from users to prioritise updates and make corrections. Even with the long editorial process of book publishing, they still get published with errors that the buyer cant correct. I am working without that process and so I know there will be errors, the difference is that I can put them right as soon as you let me know about them. Please use the 'Submit feedback' button at the top and bottom of each page to let me know about any errors you find and more importantly any suggestions you have for developing the site. What follows is a list of updates that are being made to the site as I make them. New entries will go at the top. Thank you.
Updates and Notices
I have just added a page on Exam Advice - Little things that can make a big difference. You might want to share it with your students.
And here it is - the revision pack for Logic, sets and probability on the Exam Revision Packs page.
Please find the revision pack for Mathematical models on the Exam Revision Packs page! Nearly there now. The Logic, sets and probability one should be there before Monday 17th April 2017!
So I am really pleased to be able to announce free access to my new resource for students at StudyIB.net . It is a Beta version meaning that there are some gaps and unfinished business, but there is already a lot of very useful resources there to help students prepare for their exams and I am keen to get them using it. Visit the link above or this page StudyIB.net on this website for more information.
I have spent quite a bit of time this month on re writing the Exam Revision Packs page. It now has 3 brand new complete revision packs to help students prepare for their exams, with more to follow. Visit the page to see an explanation of how they work. I am delighted to have them myself and hope that they will be useful to lots of your students too.
Following a request, I did add a solution to the Cuboid Challenge page.
While we are here, lets remind you of this section Student writing guide which is a good checklist to help students put the finishing touches on their projects. There has also been a debate about correlation and independence on the Project Problems page, which makes reference to this blog post on the topic.
Many of us will be in project season one way or another, so here is another sample in the Marked Projects section. Television Series as with the others there are full justifications for marks awarded. See example below....
Here is a blog post about the percentage perception activity and some new data we have at our disposal
See the new page Focus on Non-right angle trigonometry with the gallery of explanations for this sub-topic
NRAT Carousel gallery
This month has been primarily about a full scale proof read (and correction) of the web pages on the site. Difficult to see I know, but lots of hours involved to hopefully improve the quality of the site. What we could correct as we go we did, we have a list of everything else to work through! This was necessary and will be repeated from time to time. Next up is a proof read and correction of downloads!
I have been building this Focus on SOHCAHTOA page which includes a new set of teaching slides.
I have been doing some Number and Algebra work and have updated the Percentage Perception to elaborate on the ToK angle and include some answers. I had some nice feedback this week about that activity...
'It is bang on the money. You can just feel the percentage error equation - drop dead boring by itself - come to life in the lesson. It is really relevant to an international class and its the sort of lesson that would have an inspector dancing in the aisles - maths made relevant and allowing the exploration of something pertinent in today's society. Sweet!'
Back to school for lots of us! I started my classes with a bit of a visual warm up this year - check out this blog post
I have just made some big updates to the The 6 million question activity as I prepare to do this with my students at the start of the year. Lots more images and videos to help make this activity count!
I am building the Focus on correlation and regression page with ideas, activities and practice resources.
Here is a blog post about the IB Americas conference and some reflection on this site and conferences in general
If you haven't seen the blog post on results, then check that out!
Have added a few paragraphs to the Teaching and Learning notes section of the Focus on Calculus Concept page!
Just returned from an exciting trip to Toronto and the IB Americas conference. It was terrific to meet lots of teachers from the region and also to meet some happy subscribers face to face! Hope to see some new schools from the region on board soon.
Check out the Focus on stationary points and optimisation page - as promised.
I have been making some additions to the Focus on Calculus Concept page, including a piece about the ToK leap to using limits to build new knowledge! Am also working on a 'focus on stationary points and optimisation' page that will be published next week...
And with summer holidays come results! Hope all your students got what the needed!
Summer holidays for Northern hemisphere schools! Hope everyone has a good one! I am off to the IB Americas conference in Toronto next week. Maybe I'll bump in to some of you?
Mostly only small adjustments, corrections and additions made to pages during the month of June
Check out this new activity for thinking about frequency distributions - Frequency Distribution Match. It is part of preparations for working with the Normal Distribution. Match 12 distributions with their diagrams!
And now one on Non Right angled trigonometry. See the G & T Practice page
Exam season - cant get enough practice! There is a new set of exam style questions on right angled trigonometry on the G & T Practice page!
Another set of exam style questions on Coordinate geometry is now on the G & T Practice page
There are 10 new exam style questions for solving simultaneous equations with the GDC on the N & A Practice page.
Check out some updates to the Common Errors page ahead of May Exams!
I have added a quick idea and associated file to the Statistics Teaching Ideas about the chi squared calculator that I have used recently with a class.
Here is a new classroom activity, Box plots - why?, for looking box plots. Its one I have been using for a while with students and teachers on workshops and I find it a really powerful way of getting students to come up with the idea for themselves and then seeing its power as a comparative tool for understanding the world around us. As such, I have had quite a lot to say about it here on the Box plots - teachers notes. Much focus has been on exam style questions and teaching slides etc recently and it is nice to spend some time on another great teaching idea. I'd love to hear peoples thoughts.
A new set of teaching slides on calculus, check out Focus on Tangents and Normals
Here are two new sets of questions on Statistics that can be found on the Statistics Practice page. One on descriptive statistics and the other on Bivariate data. Both come with solutions.
Thanks to a user for pointing out some problems with 3D Uncovered which are now solved. The sketchup files can now be downloaded. I enjoyed reminding myself how useful it is to be able to look at 3D diagrams from different angles!
See the new Focus on Calculus Concept page for a new set of teaching slides on this topic along with links to activities and practice exercises.
There is a new set of exam style questions on Sequences on the N & A Practice page that covers both arithmetic and geometric sequences. Solutions are there too!
Happy New Year
This week I have added a great set of exam style questions on exponential models and their solutions to the Focus on - Exponential models page
Have been working quite hard on a new service for students - It will be a separate website with video lessons, online quizzes and more to compliment the teaching site. It will be available to individual students. Details soon and hoping to release it in Feb!
Please find a new set of exam style questions on Financial Mathematics on N & A Practice page.
There is a new page here with a Focus on Logic that includes some great teaching slides for this complex topic. See them on the gallery below
Symbolic Logic Carousel gallery
Hope everyone is looking forward to a good Christmas break wherever you are! I will be signing off for 10 days or so. A couple of new pages with teaching slideshows for Sets and probability will get published during the break Then in January, I'll post a new mock exam. Take care all - Jim
There is a new set of exam style questions on 'the Normal Distribution' available on the Statistics Practice page 10 questions, a mix of paper 1 and paper 2 style and the solutions! See the new Focus on - Exponential models page which includes teaching slides and links to activities and practice.
Just added a little section on 'Paper folding' to the Focus on - Geometric Sequences page.
Get some teaching slides and expanded sections on ToK and ATL when teaching with the Focus on - Geometric Sequences page! Lots of ideas, activities and practice for these ideas.
Another set of exam style questions on the Calculus Practice page. 110 marks on optimisation!
Here is another in the focus on series - Focus - Arithmetic Sequences with teaching activities, teaching slides, practice tasks, ToK references and Teaching and Learning notes to help with unit planning.
I have just added the latest in my series of 'Focus on' pages. This one is Focus - Chi Squared . The aim of these pages is to collect the things on the site relevant to particular syllabus items and topics. As the site gets bigger, these filters will be increasingly necessary. Also, the pages contain sets of slides for teaching and some deeper discussion of the teaching of the topic with opportunities to develop ToK and the IB learner profile. There is also discussion of approaches to teaching and learning which will be increasingly useful as unit planners become more common place
Read my first analysis of the curriculum review reports. Some serious changes in store!
Check out this new GDC Treasure Hunt activity. Great fun and terrific for reviewing/practicing/learning calculator skills
Following a number of questions on this recently I wrote a quick blog post about students using the chi squared test in their projects.
30 NEW EXAM STYLE QUESTIONS - I am really pleased to be able to add some exam style questions on Calculus to the Calculus Practice page. Find 3 sets of 10 questions on 1. General concept, 2. Tangents and normals, 3. General calculus. There are a mix of paper 1 and paper 2 style questions and the solutions. I have enlisted some help writing questions and would like to thank Dennis Oberg for writing these questions for the site.
I have just added these posters with Mathematical Quotes to get students thinking and help decorate your classrooms! Visit the page to see, download and print.
I am building this page about Mathematics in the Media listing some of my favourite examples for use in class. Plenty there already and more to come.
There is a new set of exam style questions for Logic on the L, S & P Practice page. Ten questions worth 80 marks, with solutions!
New Activity page, have great fun and do some good thinking with Nerf gun roulette
To go with the ATTL and planning page there is now an explanation of how I am going to help teachers gather evidence for Unit planning along with an example done for the sub-topic Sets of numbers based on this Sub-topic summary page template.
As part of an effort to improve past paper style questions, I have updated a question set for Numbers and Accuracy with solutions in the N & A Practice page.
A blog post about my plans for this website during my sabbatical!
So, the summer has arrived in Toulouse and I am at the start of a sabbatical from school that means, in theory, that I wont be teaching again until January 2016. The summer and the term following should see the site really develop to the next level...... Updates will be posted here. I am off on holiday for a couple of weeks now, but have scheduled some updates for that time so check the what's new section on the home page!
This weekend just passed I had some fun making this video about chi² and expected frequencies which fits nicely with the Independence Day activity....
I have been working on a new activity to help get students thinking about the Normal Distribution - coming soon!
30th May - For the last couple of weeks I have been working hard on this Student writing guide for the Internal Assessment . It is a currently 24 page guide to writing stats based projects for the IA. The tricky balance is to offer a good mix of sound advice and technical help without providing a formula for a project. I think I have done alright! Anyway, you can get the guide as it stands from the Student writing guide page as a PDF and I will continue to make more of it web based.
12th May - I have just given the Independence Day activity an overhaul having wanted to change a few things for my own use in class. I think it is tighter now and really leads students nicely to the idea that expected frequencies is an intuitive idea and not a calculation that needs to be taught. The activity sheets have been re-written and are now available as PDFs since the google docs were not so easily printed. I followed this with using the chi ² calculator idea which I talk about here in this Making Calculators blog. I'll be following that up with some Real independence tests
3rd May - There is a new notes file on the Calculus Practice now about finding where gradients are equal to zero. Reminder that these Notes Files are designed as a way to help students keep records and revise what they do. Not a complete set of notes, but not a blank canvas either. Students need to think to fill them out, but there is limited potential for them get things wrong.
26th April - I have just added a 'idea' and description for a great, practical activity to introduce calculus. Distance Time Graphs on the Calculus Teaching Ideas page. Writing about it reminded how good it can be! get a taster below!
14th April - I have been having some good conversations about Chi Squared, Regression and Causation that I have blogged about!
6th April - Here is a new revision resource called Revision Calendar I used to do this a number of years ago and have revived it this year. As simple resource to help students keep thinking about mathematics while they go on study leave!
29th March - I made a small addition to the Student Placement page which you might find useful when talking to students about choices.
22nd March - Here is a blog post I wrote about the projects my students did this year. I was really pleased with the variety and spirit in which the projects were done!
3rd March - Hi all, I would really like to start collecting some testimonials from site users and so have put this Tell us what you think. page together.
18th February - This is the first draft of a new activity I am really excited about. It is a simple activity for practicing % error, but the context is what makes it so interesting! here is the Percentage Perception page in the N&A Teaching ideas section.
Workshop weekend! - I have just a brilliant weekend doing workshops with teachers in Barcelona and in Rome - I know, someone has got to do it! Preparing for these does impede my website time a bit, but it gets my creative juices flowing so I have a number of new ideas that will go up as a result!
12th February - I have just added some elaboration to go with the presentation on the Student Placement page.
4th February - Following a request I have added a blank spreadsheet template for use in marking and moderating course work to the Marking & Moderation page.
28th January - I started a section on Student Placement since we had an evening for prospective students and many are beginning the decision making process for which mathematics course to choose. There are some presentation slides that you might find useful to show to students/parents and I have begun elaborating on them.
14th Jan - Check out the Site Development page to get an idea of what my priorities are. There is an invitation to contact me and help me set them. I have re-written this page in a way that makes more sense and will be more dynamic. I confess that I have so many plans for the site that I sometimes lose site of what is already here. The site is already huge but it is growing all the time (read this page). Let me know if you have some thoughts.
7th Jan - I added another notes file on Basic probability to the L, S & P Practice page. getting there!
6th Jan - I Published the January 2015 Newsletter. this will go to those on the e-mail list too. Some ideas, links and thoughts about Approaches to Teaching and learning.
3rd Jan - And today I made three new 'Revision Notes' files and put them on the L, S & P Practice page. As revision looms for May 2015 candidates, these are going to be really useful. Read more about what they are here - Notes Files Only a couple more to go on this section, then the calculus section and we will have the complete set. I will be using those with my students this year. See example below....
2nd Jan - Happy New Year to all! I have started as I mean to go on and have been tackling some obvious gaps on the site. Today, there are 3 new, detailed worksheets/practice exercises for probability on the L, S & P Practice page. Following requests from some users, I have made these available as PDFs, which I have also embedded in the page so you can get a quick look
I just added a quick idea to the L,S&P Teaching Ideas pages called 'Nerf Gun Roulette'. I have been having fun with that this week. It is good fun and a nice conditional probability problem. I was quite impressed that my students could solve it!
I have just added a page on the group 5 Aims and Objectives where you can download some posters for classroom display.
Here is a quick blog post about some data that crossed my path earlier today and how we might be able to use it for teaching stats or projects.
I have been making some small edits and re-arrangements under the Getting Started section to bring some things up to date.
Two more worksheets and some answers added to the Functions Practice page
Added another question and set of answers to the Logic Practice questions on L, S & P Practice
Just added 4 new IB style questions on Financial Mathematics as a document on the N & A Practice page.
Now there is another questionnaire on the Real independence tests page. Is preferred Wine Colour, dependent on Gender?
I have just posted a blog on ToK and my own personal perspective.
I have just added an activity, Human Sudoku , to help teachers and students examine ToK and Mathematics. This is particularly approachable for Studies students.
I am beginning a section on the role the IB learner Profile plays for Mathematical Studies Students
Also taking shape at the moment is this new section on Theory of Knowledge . I do feel like that ToK runs through many of the activities on the site, but I am working on this section so that it makes some of this a bit more explicit.
I have a recently begun work on writing up a new activity that ticks some boxes for estimation and ToK. Not quite finished, but already useable, The 6 million question
I have just put up a new set of IB style questions on the N & A Practice page for Standard form, Accuracy, sets of numbers and percentage error. they can be used how ever you want, but the make a nice 50 minute test all together.
I have been getting very excited about this web app I discovered called 'The Logic Lab' I think it has lots of potential for helping with logic truth tables and have been working on a big activity to go with it. Read the blog post (linked above) and watch this space.
I have remodeled the Site Guide page to include a more detailed description of what you can find on the site and a screencast. this is probably more useful for new users. Please share with anyone you think might be interested in subscribing!
Thanks to Anna Binney for point out an error on the Which Rule? activity sheet which is now corrected!
I have added another new worksheet to the Calculus Practice page on finding the equations of tangents and normals. The answers are also included.
My September 2014 Newsletter for IB Mathematical Studies is now on the site
I have added another marked project example that scored 12/20 Instagram User as this section of the website builds!
I have just added a worksheet on finding the value of gradients at a point to the Calculus Practice page
I added a blog post reflecting on the May 2014 results
Just added - 3 new IB style questions (IBSQ) on Chi Squared Independence tests. Find these on the Statistics pages.
I have just added a set of practice exercises for the Normal Distribution on the Statistics Practice page. Now working on some answers.
I am running a workshop in the UK on Technology and Secondary Mathematics Teaching organised by Douglas Butler, author of Autograph. I tweaked a few pages on this site in preparation for that and although not specifically for Maths Studies, you might find it interesting.
I have just added a page about a 'Summer Preparation' task that I have prepared for students starting the course in September.
I spent some time at the end of may and beginning of June doing a detailed analysis of the TZ2 May paper and writing a set of model answers. May 2014 TZ2 paper
May was a busy month with IA moderation for the IB. resulting from this I wrote this blog post about this year's crop of work. IA Moderation
Then I added this post about task design, the internet and The Problem with Monty Hall
I have just added 'Quick revision tests' for all of the units on the Exam Revision Packs page. These are by no means comprehensive, but are another resources students can use to practice.
In the midst of moderating Internal Assessments, I wrote a blog piece about Moderator notes
I have now added the last revision pack on Geometry and trigonometry Exam Revision Packs
I have now added the revision pack on Logic, sets and probability on the Revision Packs page. Just one to come.
I have started to put up the revision packs this week and last. There are now packs for 4 of the 6 areas on this Revision Packs page.
Revision packs are very close! Still close and apologies for the delay, but the good news is that I need them for my students for this exam session so they will be done!
So far this month I have added a couple of sets of past paper style questions one on Linear Regression and one on the Chi Squared test of independence. These can be found on the Statistics Practice page
I have just re-written the marking criteria for the IA in student friendly language. I think this cqn really help students understand what is expected of them. I will be using it as part of a 'first draft feedback' exercise with students.
I have just added some past paper style questions on the Normal Distribution to begin a collection of questions for statistics. More to follow....
I did a little reshuffle of the top pages of the site. now you can find all of the information about Intrenal and External Assessment under the heading Assessment. Whilst the 'Everything else' tab has been renamed Getting started
I have committed to providing some good revision resources based on the new syllabus in this blog post Revision resources
Happy New Year to all!
I have just made some corrections to the Mock papers I published recently. Thanks ever so much to Dania Srouij for feeding back about some of those.
I have added a brief update to this blog post on IA Issues to clarify the differences in how chi2 tests will be tested in exams and in the IA. The update is shown at the bottom of the post.
I added a short blog post to prompt some thinking about Teaching challenges for the new year!
This month saw a couple of updates related to teaching activities that went up a little bit at a time. Firstly there is the Educating Linear Regression activity which is all about using data from gapminder to look at what is happening to access to education over the last 40 years. These a great relevant stats that lend themselves nicely to some good statistical questions.
Also I posted this blog on Making calculators which is a technique I find myself employing more and more for helping kids to get under the skin of ideas.
Have just added an activity about doing Real independence tests with live data. There are links to some questionnaires and data that students can use and share, then an activity sheet to get them to work through all the issues related to independence tests along the way.
Just back from a great category 1 workshop in Barcelona where I got to meet 25 more Maths Studies teachers and exchange and share ideas.
And it is up - a full mock exam paper for use, based on the new syllabus. Find it here Exam Style Questions I haven't tried it yet and will be triple checking it soon and providing solutions.
So I have now completed a whole mock paper based opn the new syllabus. I need to tidy it up and produce a brief markscheme and it should be on the site in the next couple of days.
Today I began work on a full mock exam paper. It takes a while, but should be coming in the next two weeks.
You may also notice a new look to the site! We hope you like it!
I have just added some more past paper questions and solutions to G and T Exam Style questions. I have made the screencasts too, they will be going up soon too.
Teaching ideas for the Normal Distribution are on my agenda just now. I have just uploaded a spreadsheet called Normal to the Statistics ideas page (under quick ideas) the idea is that students try and make a normal distribution from 20 data items. The means and standard deviations are calculated for automatically as well as the percentage of the population within so many standard deviations from the mean. It is a great exercise!
After a flurry of questions from different places, I wrote this blog about The key issues with marking IA this year. Hopefully this will help us all when marking.
I have just uploaded some more 'IB style questions' on Sequences on the N and A practice page. There are 7 paper 1 questions and 2 paper 2 ones totaling 50 marks. They can be used any way you want but make a nice 50 minute assessment. Solutions to follow....
I have been working on some solutions to the geometry questions mentioned below and they should begin to be on the site soon.
