Monday

1. 8 × 12 =
$ 8 \times 12 = 96 $

2. 54 ÷ 9 =
$ 54 \div 9 = 6 $

3. 112 + 72 =
$ 112 + 72 = 184 $

4. 86 - 32 =
$ 86 - 32 = 54 $

5. The time is 3:15pm. What time is it in 70 minutes?
- 3:15pm + 70 min = 3:15 + 45 min = 4:00pm, then add remaining 25 min → 4:25pm

6. $\frac{2}{5}$ of 30 =
$ \frac{2}{5} \times 30 = \frac{60}{5} = 12 $

7. What fraction of the shape is shaded?
- Grid has 6 squares total; 1 shaded → $\frac{1}{6}$

8. Round to nearest 100: 450
- Already at 450 → 450 (since it's exactly halfway, round up) → 500

9. How many cm in 5m?
- 1m = 100cm → $ 5 \times 100 = 500 $ cm

10. 5, 25, 45, ____
- Pattern: increasing by 20 → $ 45 + 20 = 65 $

Tuesday

1. 5 × 11 =
$ 5 \times 11 = 55 $

2. 96 ÷ 12 =
$ 96 \div 12 = 8 $

3. 145 + 62 =
$ 145 + 62 = 207 $

4. 240 - 110 =
$ 240 - 110 = 130 $

5. The time is 2:15am. What time is it in 80 minutes?
- 2:15am + 80 min = 2:15 + 45 min = 3:00am, then add 35 min → 3:35am

6. $\frac{2}{8}$ of 16 =
$ \frac{2}{8} = \frac{1}{4} $, so $ \frac{1}{4} \times 16 = 4 $

7. What fraction of the shape is shaded?
- Grid: 6 squares, 2 shaded → $\frac{2}{6} = \frac{1}{3}$

8. Round to nearest 100: 720
- 720 is closer to 700 than 800 → 700

9. How many cm in 2.2m?
- $ 2.2 \times 100 = 220 $ cm

10. 4.5, 4.1, 3.7, ____
- Decreasing by 0.4 → $ 3.7 - 0.4 = 3.3 $

Wednesday

1. 9 × 7 =
$ 9 \times 7 = 63 $

2. 28 ÷ 4 =
$ 28 \div 4 = 7 $

3. 96 + 96 =
$ 96 + 96 = 192 $

4. 91 - 60 =
$ 91 - 60 = 31 $

5. The time is 4:20pm. What time is it in 55 minutes?
- 4:20pm + 55 min = 4:20 + 40 min = 5:00pm, then add 15 min → 5:15pm

6. $\frac{1}{5}$ of 60 =
$ \frac{1}{5} \times 60 = 12 $

7. What fraction of the shape is shaded?
- Grid: 6 squares, 4 shaded → $\frac{4}{6} = \frac{2}{3}$

8. Round to nearest 100: 3,120
- Look at tens digit: 2 < 5 → round down → 3,100

9. How many m in 200cm?
- $ 200 \div 100 = 2 $ m

10. 99, 97, 95, ____
- Decreasing by 2 → $ 95 - 2 = 93 $

Thursday

1. 8 × 6 =
$ 8 \times 6 = 48 $

2. 49 ÷ 7 =
$ 49 \div 7 = 7 $

3. 45 + 47 =
$ 45 + 47 = 92 $

4. 365 - 125 =
$ 365 - 125 = 240 $

5. The time is 1:50am. What time is it in 40 minutes?
- 1:50am + 40 min = 2:30am

6. $\frac{3}{4}$ of 24 =
$ \frac{3}{4} \times 24 = 18 $

7. What fraction of the shape is shaded?
- Grid: 6 squares, 2 shaded → $\frac{2}{6} = \frac{1}{3}$

8. Round to nearest 100: 2,850
- Tens digit is 5 → round up → 2,900

9. How many m in 450cm?
- $ 450 \div 100 = 4.5 $ m

10. 0.3, 0.5, 0.7, ____
- Increasing by 0.2 → $ 0.7 + 0.2 = 0.9 $
