For the last few weeks my family is up to our ears in maths exercises and brain teasers as my daughter has developed a big interest.
I am setting up a “newsletter” for puzzles. Once in a few days I would send a few exercises. Readers can send their solutions if they want, and I will mark them. This would cost a few pounds per month.
To sign up, email to mathtime@autkin.net with your kid(s) age, grade and goals.
