What to do
1)Use the strategy of splitting a number into parts to do these additions.
2) Do the problems in your head first.
3) Check you are correct by writing them down. Show them like the examples above.
1) 28 + 14 split 14 into 12 + 2 and then make 28 into a tidy number by adding 2. 28 + 14 = 28 +12 + 2 = 20 + 12 = 32
2) 76 + 9 = 76 + 5 + 4 = 80 + 5 = 85
3) 37 + 15 = 37 + 10 + 5 = 40 + 10 = 50 +5 = 55
4) 46 + 17 = 46 + 10 + 7 = 56+ 7= 63
5) 68 + 24= 68 + 22 + 2 = 70 + 22 = 82
6) 48 + 37 = 48 + 35 + 2 = 50 + 35 = 85
7) 29 + 62 = 29 + 61 + 1= 30 + 61=91
8) 18 + 63= 18 + 61+2=20+61=81
(9) 55 + 17 = 55+15+2=57 + 15=72
(10) 29 + 54 = 54 + 6 + 23 = 60 + 23 = 83
(11) 38 + 17 = 38 + 15 + 2=41 + 15=56
(12) 37 + 54 = 54 + 31 +6 =60 + 31 = 91
(13) 69 + 73 = 69 + 1 + 72 = 70 + 72 = 142
(14) 78 + 45 = 78 + 43 + 2 = 80 + 43 = 123
(15) 27 + 57 = 27 + 54 + 3 = 30 + 54 = 84
16) 19 + 64 = 64 +10 + 9 = 64 + 10 = 74 +9 = 84
(17) 27 + 46 = 27+43+3= 30+43=73
(18) 38 + 75 = 38+ 73+2=40 + 73= 103
19) 47 + 86 = 86 + 43 + 4 = 90
(20) 34 + 68 = 68 + 30 + 4= 72 + 4 = 76 + 30 = 106
(21) 58 + 86 = 86 + 50 + 8 = 94 + 50=144
22) 38 + 74 = 74+30+8=82+30=112
(23) 95 + 29 = 95 + 20 + 9 = 104 + 20 = 124
(24) 88 + 36 = 88 + 30 + 6 = 94 + 30 = 124
