About This Lesson
Test students skills with substitution into expressions in this PowerPoint game based around The X-Factor. Suitable as a long starter or expanded into a full lesson. Split the class into four groups who taken on the expressions related to each judge. Lots of useful work on misconceptions can crop up; such as negative numbers and dividing by small numbers.NOW UPDATED WITH NEW JUDGES!!!
A really nice idea to try to make substitution a bit more fun - well done! Will try it out with a couple of classes
