Sequences notation connect thoughts

Connect thoughts activity to practice writing rules for arithmetic and geometric sequences using 'Un' notation. Answers on second page. Pupils to write answer on a post it note to claim a square. Aim is to get 4 in a line before their partner (or can be used individually - in practice I find many pupils actually just want to answer all the questions!). I would recommend specifying vertical or diagonal line so pupils try each type of question, or can use the different levels for differentiation.
