NRICH maths club Celebrating ten years online this site started well and has continued to grow, now claiming to be the largest maths site online. It includes a huge variety of free resources.
A real winner, especially if you have a bright child who enjoys investigating maths for the fun of it. Activities include puzzles, problem solving, investigations and games to play against the computer. A wide range of topics are included but the best way to get started is to look at this month’s edition and try some activities. For this June the main theme is angles and triangles, with trig for older pupils.
