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 305 problems (153 SL + 152 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 #153There 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 probability distributions► syllabus content for Statistics & Probability Topic: SL syllabus (see syllabus sections 5.7, 5.8 & 5.9); HL syllabus (see syllabus items 5.5, 5.6 & 5.7).It is better to teach probability distributions after teaching statistics (descriptive statistics) and probability (probability of events). In other words,...
Quick links:► downloadable teaching materials for polynomial functions & equations► syllabus content for the Functions & Equations Topic: HL syllabus (see syllabus section 2.5).The syllabus items related to polynomial functions & equations are included in the HL syllabus sections 2.5, 2.6 & 2.7. Specifically this includes: polynomial functions & their graphs, factor & remainder...
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 sequences & series► syllabus content for the Algebra Topic: SL syllabus (see syllabus section 1.1); HL syllabus (see syllabus section 1.1).Although it's interesting (and I would say worthwhile) to discuss sequences that are defined by recursive (or iterative) formulas - such as the Fibonacci sequence - the fact is that the only sequences/series...
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 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...
Quick links:► downloadable teaching materials for probabilities of events► syllabus content for the Statistics & Probability Topic: SL syllabus (see syllabus sections 5.5 & 5.6 ); HL syllabus (see syllabus sections 5.2-5.4 ).This section of the syllabus concerned with the probabilities of events (I sometimes also refer to this section as general probability) has some overlap with the other...
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...
Available ... Sample Paper 1 and Paper 2 mock exams for SL & HL→ 3 pairs (sets) of exams for both SL and HL ←Now available a full set of mock exams for Set C:SL Papers 1 & 2, and HL Papers 1 & 2There is a strong argument that the most important assessments - other than the official IB exams taken in May or November - are the mock exams (i.e. 'practice' exams) that students...

probability distributionsScott, Thanks for your feedback. I re-did my solution to Q.5 part (b) on the 5-5-30v2_HL_probability_distributions exercise set, and I came up with 0.583 (the answer given on the ex set). I have displayed the work I did on my GDC (TI-Nspire)...
