Groupers are designed as a quick way at the start of a lesson to get students into random groups or pre planned groups. Once students are grouped together, you may wish to split a group of six into two threes. This activity allows students the opportunity to practise their mental maths and problem solving skills.
The activity also creates an opportunity for students to move around the classroom to talk to each other about the maths. Currently I have made simple number groupers, with questions of varying difficulty, and I’ve also made a Christmas themed grouper.
