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 370 problems (184 SL + 186 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 #186There 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...
One of the more significant changes in the new IB maths courses is a completely revamped Paper 3 exam (HL level only). As the Analysis & Approaches Guide puts it, the Paper 3 exam consists of "two compulsory extended response problem-solving questions." Thus, the stated objective of the Paper 3 exam is to assess a student's problem solving skills. There is no additional syllabus...

Teaching in any curriculum system with external exams that assess a student's knowledge of content contained in a prescribed syllabus demands not only a certain level of mathematical knowledge and effective teaching methods, but also requires the teacher to make a significant effort in planning the organizational aspects of teaching the course. One of the fundamental ingredients of this 'course...
This 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 also added some review quizzes on the bottom of this page. I welcome feedback on any of these materials. Just submit a comment at the bottom of the page.Calculus Tests Test_SLHL_Intro_Diff_Calculus_v1...
The following is a suggested teaching sequence (plan) for the content in the Maths SL syllabus and the Maths HL Core syllabus. Of course, there is no single teaching sequence which is best for everyone - so it is certainly worth the effort to consider this suggested plan with a critical eye. Nevertheless, I have come up with this teaching sequence after quite a bit of experimentation and fine-tuning....

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...
Great site. Dense with great ideas and useful printable student material. It has added an extra dimension to my teaching and given me several successful plan B options. Well done Tim.
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...
