Multiplication Problems:
1.
35 × 5
Break it down:
30 × 5 = 150
5 × 5 = 25
Add them: 150 + 25 =
175
2.
62 × 9
Think of 62 as 60 + 2
60 × 9 = 540
2 × 9 = 18
Add: 540 + 18 =
558
3.
42 × 8
40 × 8 = 320
2 × 8 = 16
Add: 320 + 16 =
336
4.
54 × 7
50 × 7 = 350
4 × 7 = 28
Add: 350 + 28 =
378
5.
83 × 9
80 × 9 = 720
3 × 9 = 27
Add: 720 + 27 =
747
6.
76 × 7
70 × 7 = 490
6 × 7 = 42
Add: 490 + 42 =
532
7.
29 × 6
20 × 6 = 120
9 × 6 = 54
Add: 120 + 54 =
174
8.
67 × 8
60 × 8 = 480
7 × 8 = 56
Add: 480 + 56 =
536

Division Problems:
We’ll divide and check if the answer makes sense by multiplying back.
1.
54 ÷ 2
Half of 54 is
27 → Check: 27 × 2 = 54
✔
2.
78 ÷ 6
How many times does 6 go into 78?
6 × 13 = 78 → So,
13
3.
33 ÷ 3
3 goes into 33 eleven times →
11 (because 3 × 11 = 33)
4.
91 ÷ 7
7 × 13 = 91 → So,
13
5.
48 ÷ 4
4 × 12 = 48 → So,
12
6.
96 ÷ 8
8 × 12 = 96 → So,
12
7.
70 ÷ 5
5 × 14 = 70 → So,
14
8.
99 ÷ 9
9 × 11 = 99 → So,
11
