9 years of age is a very important time in a child's development. Many children at this age start to develop logical thinking which continues very rapidly. One of the best ways to nurture this development is to stimulate their mind with mathematics. Here we have two sample lessons that can help you to determine the level of problems that will engage your child. The other problems are also inside. Enjoy.

Join me for meaningful learning that will have lasting value.

Much of the content takes a student through the experience of solving a problem from scratch, learning a concept rigorously or applying a concept to a problem. This process is filmed and presented here with basically no editing. To be truly great at maths you cannot just memorise disconnected facts you need to learn how to think and how to learn. For younger students we have the luxury of applying the things we learn in math olympiad problems. I look forward to seeing you in class!
