Some things look better and are more memorable on the screen than on the page. Red Hot Websites: Maths has been compiled by a maths teacher and secondary students. It provides addresses and brief reviews of dozens of sites where key stage 3 pupils can juggle with negative and positive numbers, practise transformations or perform complex tasks with an interactive protractor. For enlivening lessons, try 101 Red Hot Maths Starters. Calculator races and imaginary cubes all contribute to the instructive fun.
