Get students’ brains switched on and practising pre-algebra concepts involving addition and subtraction. Students pick up cards, read the problems and solve the problems as quickly as they can. The person who solves the problem first keeps the card. The player with the most cards at the end wins!
Use this fun activity in numeracy rotations or as a fast finisher activity.
Laminate gameboards for a quick and effective maths rotations activity or use the black and white versions that students can decorate themselves.
