Objectives: KS1 Maths, Year 2 and adapted for Year 1. Add numbers using concrete objects and pictorial representations, e.g. number squares, to add 1- and 2-digit numbers. Add/subtract mentally two 2-digit numbers by counting on in 10s and 1s. Recognise and use symbols for pence (p) and use coins to solve simple problems involving addition and subtraction. Targets: I can add and subtract 10’s and 1p coins. I can find totals using coins up to 100. Year 1 Adding 1 more/1 less Finding totals up to 20. Notes for teachers Children can complete the challenge individually or in pairs. Timing the activity helps keep the children focused, keep the totals a secret until the ‘big reveal’ to add competition. Ideally it would be good if the children use real 10p and 1p coins. Included: Prerequisite activity, adding tens only grid. Blank grid maze with coloured paths to laminate and you can add your own numbers depending on your Year group. Purse print out.
