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 the challenge of solving the more difficult or unfamiliar problems. The site is easy to work with and the amount of material there has made my life so much easier and put more hours into my day. My students and I throughly enjoy working with site for our curr

The InThinking Maths website is a very beneficial and user-friendly online guide for IB teachers. You can get an answer to all of your questions. There are all sort of materials and support, many samples of course designs, explorations, exams, teaching materials and resources. Especially useful is the information on how to assess explorations and the extended essay. I recommend confidently the InThinking Maths website to all IB Maths teachers

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 groups and often find they are doing the discriminating question before long.

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 the course, and is a great resource for teaching and assessment materials. The leveled questions and tests that go along with each syllabus item are especially useful for teachers looking to add to their course material.
