Calcula, sumando según número que se encuentra fuera del circulo y pon la respuesta en el circulo:
[pic 1][pic 2][pic 3][pic 4][pic 5][pic 6][pic 7][pic 8][pic 9][pic 10][pic 11][pic 12][pic 13][pic 14][pic 15][pic 16][pic 17][pic 18][pic 19][pic 20][pic 21][pic 22][pic 23][pic 24][pic 25][pic 26][pic 27][pic 28][pic 29][pic 30][pic 31][pic 32][pic 33][pic 34][pic 35][pic 36][pic 37][pic 38][pic 39][pic 40][pic 41][pic 42][pic 43][pic 44][pic 45][pic 46][pic 47][pic 48][pic 49][pic 50][pic 51][pic 52][pic 53][pic 54][pic 55][pic 56][pic 57]
Decomposing number bond:
One way to add is to break down the 2-digit number into tens and ones.
23 + 6 = 29 add the ones[pic 58][pic 59][pic 60]
3 + 6 = 9[pic 61][pic 62]
Add the tens and ones[pic 63][pic 64][pic 65][pic 66]
20 + 9 = 29[pic 67]
43 + 5 = add the ones[pic 68][pic 69][pic 70][pic 71]
+ = [pic 72][pic 73][pic 74][pic 75][pic 76]
Add the tens and ones[pic 77]
+ = [pic 78][pic 79][pic 80][pic 81]
66 + 2 = add the ones[pic 82][pic 83][pic 84][pic 85]
+ = [pic 86][pic 87][pic 88][pic 89][pic 90]
