Hallowe'en Codebreakers for Algebra Substitution

This is a full lesson worksheet that contains the starter and a main activity. I used it to introduce Substitution in Algebra to Year 7's, who had learnt to collect like terms in algebra the two lessons before. At the start, remind the pupils of terminology, 2g, ab, and do an example that spells out hello to start with. The students loved it, and forgot they were doing Maths whilst playing the game at the back of the worksheet - Skeleton-opoly. You&'ll need counters and dice to do this lesson.
