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, 18501891)

I really like the continuously expanding InThinking Maths HL & SL resources. I always find something useful among the plentiful, practical, wellformatted resources  including notes, assignments, assessments, and interesting student pages. Absolutely...
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.

Tim, Thanks a million.

Denise, Thanks very much for pointing out that something was wrong with Q.1 on Differentiation Practice 2 exercise set. The answer/solution is correct for Q.1. It's the instructions for the question that were incorrect. The given function...

The answer to #1 on Differentiation Practice 2 is incorrect. Any chance you could update with a corrected Worked Out Solutions? Thanks!

Vivek, I generally do not recommend for an HL Exploration to focus on curve fitting using technology because the student will have little opportunity to demonstrate their knowledge of the mathematics being applied. I suggest taking a look at...

I mean, how high is it graded is it is done with GeoGebra where curve fitting is done with only a few points ?

it is not a comment but a question : How is an IA on say, Modelling Batman Logo" in HL ?

Paul, Thanks for spotting the errors. The graph in (f) will need to be corrected. For (g), domain is x>=7/2, x not equal to 4; and you've pointed out correct range for (h). Thanks very much for your feedback. I will make corrections to the...

I believe there are errors in the solution key to HL Mock Set C Paper 2 Q9g and Q9h. In 9h, the domain of the composition cannot include 3 as the domain of f is greater than or equal to 7/2. Also, in 9h the range of the composition is y less...

Patrick, Thanks for your query. I'm working hard on the next set (set D) of sample mock exams for SL and HL. The SL Paper 1 and SL Paper 2 mocks will be ready this week and the HL mocks should be ready next week. Hope that works for you.

Hi Tim, When should we expect 2019 sample mocks for both Sl and HL math? Thanks.

Hi Tim, Sorry if this question has already been asked you: when should we expect 2019 mock exam, both SL and HL. Thanks.

Omneya, Good question. I recommend that students use Times New Roman font, size 12 with spacing of 1.5
