Monday

1. 60 × 4 =
$ 60 \times 4 = 240 $

2. 630 ÷ 9 =
$ 630 \div 9 = 70 $

3. 254 + 254 =
$ 254 + 254 = 508 $

4. 460 - 125 =
$ 460 - 125 = 335 $

5. Area of a shape that is 15m × 10m?
Area = length × width = $ 15 \times 10 = 150 \, \text{m}^2 $

6. $ \frac{9}{10} - \frac{8}{10} = $
Same denominator: $ \frac{9 - 8}{10} = \frac{1}{10} $

7. $ 4^2 = $
$ 4 \times 4 = 16 $

8. 45cm = ___ m
$ 1 \, \text{m} = 100 \, \text{cm} $ → $ 45 \, \text{cm} = \frac{45}{100} = 0.45 \, \text{m} $

9. Order decimals in ascending order: 7.22, 7.02, 7.32, 3.2
Compare:
- 3.2
- 7.02
- 7.22
- 7.32
So: 3.2, 7.02, 7.22, 7.32

10. Fill in the missing operation: 11 ___ 11 = 121
$ 11 \times 11 = 121 $ → ×

Tuesday

1. 80 × 7 =
$ 80 \times 7 = 560 $

2. 320 ÷ 8 =
$ 320 \div 8 = 40 $

3. 188 + 122 =
$ 188 + 122 = 310 $

4. 635 - 124 =
$ 635 - 124 = 511 $

5. Area of a shape that is 9m × 50m?
$ 9 \times 50 = 450 \, \text{m}^2 $

6. $ \frac{2}{3} - \frac{1}{3} = $
$ \frac{2 - 1}{3} = \frac{1}{3} $

7. $ 8^2 = $
$ 8 \times 8 = 64 $

8. 5.3m = ___ cm
$ 1 \, \text{m} = 100 \, \text{cm} $ → $ 5.3 \times 100 = 530 \, \text{cm} $

9. Order decimals in descending order: 0.1, 0.11, 0.01, 1.1
Compare:
- 1.1 (largest)
- 0.11
- 0.1
- 0.01 (smallest)
So: 1.1, 0.11, 0.1, 0.01

10. Fill in the missing operation: 82 ___ 94 = 176
$ 82 + 94 = 176 $ → +

Wednesday

1. 30 × 9 =
$ 30 \times 9 = 270 $

2. 900 ÷ 9 =
$ 900 \div 9 = 100 $

3. 361 + 210 =
$ 361 + 210 = 571 $

4. 78 - 34 =
$ 78 - 34 = 44 $

5. Area of a shape that is 23m × 20m?
$ 23 \times 20 = 460 \, \text{m}^2 $

6. $ \frac{5}{6} - \frac{4}{6} = $
$ \frac{5 - 4}{6} = \frac{1}{6} $

7. $ 9^2 = $
$ 9 \times 9 = 81 $

8. 632cm = ___ m
$ 632 \div 100 = 6.32 \, \text{m} $

9. Order decimals in ascending order: 3.06, 3.6, 3.3, 3.03
Compare:
- 3.03
- 3.06
- 3.3
- 3.6
So: 3.03, 3.06, 3.3, 3.6

10. Fill in the missing operation: 42 ___ 18 = 24
$ 42 - 18 = 24 $ → −

Thursday

1. 40 × 10 =
$ 40 \times 10 = 400 $

2. 160 ÷ 4 =
$ 160 \div 4 = 40 $

3. 99 + 79 =
$ 99 + 79 = 178 $

4. 512 - 108 =
$ 512 - 108 = 404 $

5. Area of a shape that is 11m × 10m?
$ 11 \times 10 = 110 \, \text{m}^2 $

6. $ \frac{3}{7} - \frac{2}{7} = $
$ \frac{3 - 2}{7} = \frac{1}{7} $

7. $ 11^2 = $
$ 11 \times 11 = 121 $

8. 0.45m = ___ cm
$ 0.45 \times 100 = 45 \, \text{cm} $

9. Order decimals in descending order: 2.15, 2.51, 2.1, 2.01
Compare:
- 2.51
- 2.15
- 2.1
- 2.01
So: 2.51, 2.15, 2.1, 2.01

10. Fill in the missing operation: 360 ___ 6 = 60
