What to do

1)Use the strategy of splitting a number into parts to do these additions.
3) Check you are correct by writing them down. Show them like the examples above.

1) 28 + 14=42
Split the 14 into 10 + 4, 28 + 10 = 38, 38 + 4 = 42
2) 76 + 9=85
Split the 76 into 70 + 6 , 6 + 9 = 15, 15 + 7
3) 37 + 15=52
Split the 15 into 10 + 5, 10 + 37 = 47, 47 + 5 = 52
4) 46 + 17= 63
Split the 17 into 10 + 7, 10 + 46 = 56, 56 + 7 = 63
5) 68 + 24=92
Split the 24 into 20 + 4, 68 + 20 = 88, 88 + 4 = 92
6) 48 + 37=85
Split the 37 into 30 + 7, 48 + 30 = 78, 78 + 7 = 85
