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.
If you are interested in Tim Garry visiting your school to work with teachers and/or students, please contact us.

very soon .... launch of new Analysis & Approaches siteOne of the tasks that has slowed me down in getting the new Analysis & Approaches site (aka 'Analysis site') ready is composing a Teaching Plan for the course. I'm happy to post below my Analysis-teaching plan v5. Please understand that in my Teaching Plan the list of course units (SL & HL), the sequence in which they are...
There are currently 396 problems (198 SL + 198 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 DayHL Problem of the Day #198There 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...
Quick links:► downloadable teaching materials for function basics and composite & inverse functions► syllabus content for the Topic: SL syllabus (see syllabus section 2.1); HL syllabus (see syllabus section 2.1)Function basics include items such as:▪ determining the domain and range of a given function▪ determining whether a function is an even or an odd function (type of symmetry)▪...
Quick links:► downloadable teaching materials for binomial theorem► syllabus content for the Algebra Topic: SL syllabus (see syllabus section 1.3); HL syllabus (see syllabus section 1.3).The first significant difference between SL and HL in terms of teaching the binomial theorem arises from the need to calculate binomial coefficients, or combinatorial numbers - that is, combinations of n items...
Quick links:► downloadable teaching materials for sequences & series► syllabus content for the Algebra Topic: SL syllabus (see syllabus section 1.1); HL syllabus (see syllabus section 1.1). challenge: What is the missing last number in the following sequence?\(10,\;\;11,\;\;12,\;\;13,\;\;14,\;\;20,\;\;22,\;\;101,\;\;?\)[click on 'eye' for answer]answer: 1010each number has a value...
here's an interesting problem (presented in GeoGebra applet below) to challenge your students ... solution will be appearing soonclick here to jump down to the Calculus TestsThis page contains several unit tests on calculus - differential calculus and integral calculus for both SL and HL. Most of the tests below have worked solutions (solution keys) available as a separate document. I've...
Quick links:► downloadable teaching materials for quadratic functions & equations► syllabus content for the Functions & Equations Topic: SL syllabus (see syllabus section 2.4); HL syllabus (see syllabus section 2.6).Although the syllabus content for quadratic functions & equations is quite similar between the SL and HL courses, there are some differences to note.For example, in the...
Quick links:► downloadable teaching materials for exponents & logarithms► syllabus content for the Algebra Topic: SL syllabus (see syllabus section 1.2); HL syllabus (see syllabus section 1.2).It's absolutely critical that students have a firm understanding of the relationship between exponential expressions/functions and logarithmic expressions/functions. When covering this material it...
Four 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 for each exam.New original specimen papers (SL & HL) will be appearing in the near future for the Analysis &...
Quick links: ► downloadable teaching materials for transformations of graphs ► syllabus content for the Topic: SL syllabus (see syllabus section 2.3); HL syllabus (see syllabus section 2.3)It's very important for students to have a complete and fluent understanding of the following types of transformations that can be applied to the graph of a function: ▪ translations - horizontal &...
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...
I highly recommend that HL teachers use your site. I am still amazed at all it has to offer. The wealth of material has made it so much easier for me to provide my students with problems that will help them learn any thing from the basics to accepting...

exp & log functions & eqnsThank you very much for your feedback. I really appreciate it.

exp & log functions & eqnsHi Norazila, Thanks for your query - a good one. I must admit that Q.3 on the SLHL exponential modelling exercise set is not well constructed (I need to make some changes to it). The answers for 3(a) were computed by using the model population=175(1+0.8)^t,...

exp & log functions & eqnsHi, i would like to know if anyone already try this set of questions exercise set 2-6(4)-25v2 SLHL (for Question #3). I tried quite a few times on questions #3(a)(iii) and #3(a)(iv) but I did not get the answer given in the solution key provided. I...

Solution: 'exact ratio of areas' problemA very nice problem that would be great to use any time but especially during the study of trig.

HL Problem of the DayThank my student!! He is the one who caught it. I made the same mistake! Thanks for your site. You are truly helping me out.
7 Oct Tim Garry
HL Problem of the DayHi Jarod, You're absolutely correct. I should have specified that m cannot be zero; or at least said it had to be a quadratic equation which would have implied that. I've corrected the wording of the instructions for HL Problem 48. Thanks for...

HL Problem of the DayIn problem #48 do we have to exclude m=0 from the beginning? If m=0 then there will only be one real solution.
