This is based on a resource by Stacy Brookes, but adapted so that it’s suitable for pupils who have just been introduced to algebraic notation for the first time. I used it with a mixed attainment Year 7 class in their second lesson on algebra. We’d already looked at numerical function machines. The intention was that they’d practise basic algebraic notation such as 3 x a = 3a. I went through question 1 while they filled it in, then they completed the rest of the sheet independently.
