Quote of the day
Many who have had an opportunity of knowing any more about mathematics confuse it with arithmetic, and consider it an arid science. In reality, however, it is a science which requires a great amount of imagination.
(Sofia Kovalevskaya, 1850-1891)
Textbooks for Math HL and Math SL. Two textbooks written by Tim Garry and Ibrahim Wazir that are fully revised 2nd editions providing comprehensive coverage for the new 2014 syllabuses. Each textbook comes with an e-book (accessed through a website) containing a complete digital copy of the text along with numerous additional material.

There are currently 360 problems (180 SL + 180 HL) with more problems added every week. There are separate pages for the SL Problem of the Day and for the HL Problem of the DaySL Problem of the Day #180There are two growing sets of 'problems' (one for SL and another for HL) with new 'problems' added every week to each set (along with a worked solution). The idea behind the Problem...
The May 2019 IB examination session is nearly finished. All the IB mathematics exams occurred last week. Teachers are eager to scrutinize an exam after it has been made available 24 hours after students have taken it. This usually leads to some interesting discussion amongst teachers about specific exam questions and their solutions. Some years I manage to summon enough time and energy to write my...
The mathematics courses in the International Baccalaureate Diploma Programme (IBDP) will be very different starting in August 2019 (first exams in May 2021). The changes are certainly the most substantial since the addition of an internal assessment task to IBDP mathematics nearly 20 years ago, and maybe the biggest changes for mathematics since the IBDP began 50 years ago.new InThinking sites for...
This page contains several unit tests on calculus - differential calculus and integral calculus for both HL and SL. Most of the tests below have worked solutions (solution keys) available as a separate document. I've also added some review quizzes on the bottom of this page.Calculus Tests Test_SLHL_Intro_Diff_Calculus_v1 [4 questions with no GDC; 5 questions with GDC allowed]syllabus content...
NEW P1 and P2 mock exams (new 2019 sets D) for both SL and HLSample Paper 1 and Paper 2 mock exams for SL & HLFour sets (A, B, C & D) of mock exams (pairs of Paper 1 & Paper 2 exams) for both Maths SL and Maths HL are available on the Sample Mock Exams page (16 exams in all). These original mock exams do not contain any past IB exam questions. A markscheme / solution key is available...
Quick links:► downloadable teaching materials for trigonometric functions, equations & identities► syllabus content for the Trigonometry Topic: SL syllabus (see syllabus sections 3.2-3.5); HL syllabus (see syllabus sections 3.2-3.6)A key aspect of solving trigonometric equations is whether or not an exact solution is required. It is very important that students get sufficient practice in solving...
This section contains collections of exam review questions for both HL and SL. There are three sub-pages included under this page:1. Sets of SL(HL) Review Exercises2.

Quick links: ► downloadable teaching materials for angles, circles, arcs & sectors ► syllabus content for the Trigonometry Topic: SL syllabus (see syllabus section 3.1); HL syllabus (see syllabus section 3.1) Most questions involving circles, radian measure, arcs and sectors require what I like to refer to as geometric problem solving. This kind of problem solving puts a lot of emphasis on...
Quick links:► downloadable teaching materials for areas & volumes► syllabus content for the Calculus Topic: SL syllabus (see syllabus section 6.5); HL syllabus (see syllabus sections 6.5).Whether using integral calculus to compute the area under a curve, area between curves, or the volume of a solid of revolution, I think it's very important for students to have a clear visual understanding...
I highly recommend any IB Mathematics teacher who is seeking expert guidance on how best to teach either Standard Level or Higher Level Mathematics in today's classroom to subscribe to the InThinking website. It is an invaluable resource for both...
Tim's InThinking site has been invaluable to me as a new IB teacher. Before starting any new syllabus item, I use the site to gain a better understanding of the types of problems that my students need to be able to solve. It has helped me to format...
I love the "accessible" to "discriminating" levelled questions. They are great for differentiation in the classroom - especially as time in the IB classroom is so precious. Students start work at their own comfort level, discuss in...

descriptive statisticsKevin, Excellent idea. In fact, I was working on that the past few weeks and was hoping to release it before this May IB exam session but did not manage. Hope to do so soon.

descriptive statisticsHi Tim, Are your accessible to discriminating questions available as one file? They'd be very good for making a revision document that touches on all topics.

triangle trigonometry & applicationsI read what you said again, I understand the ambiguity you were talking about.
12 May Omolade Kadiri
triangle trigonometry & applicationsTim thank you for your speedy reply. I would say if the question is reworded like you say, then I agree that the answer is 278degrees but the original wording suggests that the answer is different. The bearing of X from a lighthouse is different...

triangle trigonometry & applicationsOmolade, In Q.3 the bearing of 278 degrees given in the solution is the direction one would travel from X to Y; hence, it is the bearing of Y from X. So, it is correctly stated in the question and in the solution. I do think that the wording...

implicit differentiation & related rates (HL)Beth, Thanks for your query. I have posted a worked solution for the accessible HL Q1 above (it's below discriminating HL Q3). You'll need to click on the 'eye' to reveal the solution. I hope it helps.
