Pairs to 10.
1. What are they...... make a list of the ones you can think of.
2. Find the pair to 10 to solve these and record.
16 + 4 = 12 + 8 = 13 + 7= 6 + 14 =
37 + 3 = 48 + 2 = 22 + 8 = 54 + 6 =
3. Use the pairs to 10 to work out these ones..... a bit more thinking this time 
12 + 9 + 11 + 8 = 16 + 17 + 4 + 3 =
22 + 15 + 5 + 8 = 19 + 21 + 13 + 7 =
Make up a couple of your own and challenge mum or dad to find the pairs to 10 first to work them out.
