Let’s Practise
Partition into tens and ones. 31 = ? + ?
1
13 = ? + ?
24 = ? + ?
42 = ? + ?
? + ? = 22
? + ? = 33
1 11 21 31 41 51 61 71 81 91
2 12 22 32 42 52 62 72 82 92
3 13 23 33 43 53 63 73 83 93
4 14 24 34 44 54 64 74 84 94
5 15 25 35 45 55 65 75 85 95
6 16 26 36 46 56 66 76 86 96
7 17 27 37 47 57 67 77 87 97
8 18 28 38 48 58 68 78 88 98
9 19 29 39 49 59 69 79 89 99
10 20 30 40 50 60 70 80 90 100
Partition each yellow number. What is the same, what is different each time?
2
Partition each blue number. What do you notice?
E
Complete the additions. 40 + 5 = ?
50 + 4 = ?
? = 60 + 2
? = 20 + 6
30 + ? = 39 93 = ? + 3. Can you also find the largest and the smallest number?
