#### 2. Rounding 48,492

- To the nearest 100:
Look at tens digit (9). Since it’s ≥5, round up.
48,492 → 48,500

- To the nearest 1,000:
Look at hundreds digit (4). <5, so round down.
48,492 → 48,000

- To the nearest 10,000:
Look at thousands digit (8). ≥5, so round up.
48,492 → 50,000

✔ Answers:
- 100: 48,500
- 1,000: 48,000
- 10,000: 50,000

#### 3. Multiplication Patterns

Given:
8 × 10 = 80

Now:
- ___ × 10 = 800 → 80 × 10 = 800 → ✔ 80
- 800 × ___ = 8,000 → 800 × 10 = 8,000 → ✔ 10
- 8,000 × 10 = ___ → 8,000 × 10 = 80,000

✔ Fill in:
- 80
- 10
- 80,000

#### 4. Complete the Table

| IN | OUT |
|----|-----|
| 2 | 6 |
| 3 | 9 |
| 4 | 12 |
| ? | ? |

Look for pattern:
- 2 → 6: 2 × 3 = 6
- 3 → 9: 3 × 3 = 9
- 4 → 12: 4 × 3 = 12

So the rule is: Multiply by 3

Next input: 5 → 5 × 3 = 15

✔ Rule: ×3 or Multiply by 3
Next row: 5 | 15

#### 5. Measurement Conversions

- 1 meter = ___ centimeters
✔ 100 centimeters

- 300 centimeters = ___ meters
300 ÷ 100 = 3 → ✔ 3 meters

Now fill in equations:
- ___ × ___ = ___ → 1 × 100 = 100
- ___ ÷ ___ = ___ → 300 ÷ 100 = 3

✔ Answers:
- 1 meter = 100 cm
- 300 cm = 3 m
- 1 × 100 = 100
- 300 ÷ 100 = 3

Tuesday

#### 1. Solve. Shade to represent: 1/2 = □/4

We know:
- 1/2 = 2/4

So, fill in: 2

Shading: Two out of four parts shaded in the circle (or both circles split into quarters, shade two total).

✔ Answer: 2

---

#### 2. Solve. Shade to represent: 1/4 + 2/4

- 1/4 + 2/4 = 3/4

Shade three out of four rectangles.

✔ Answer: 3/4

---

#### 3. Multiplication Problems

Solve using grid method:

##### a) 34 × 28

Break it down:
```
34
×28
----
272 ← 34 × 8
680 ← 34 × 20
----
952
```

✔ 34 × 28 = 952

##### b) 74 × 36

```
74
×36
----
444 ← 74 × 6
2220 ← 74 × 30
----
2664
```

✔ 74 × 36 = 2,664

---

#### 4. Associative Property

Complete:
3 × (4 × 2) = (3 × ___) × 2

Grouping changes — but product stays same.

Left side: 3 × (4 × 2) = 3 × 8 = 24

Right side: (3 × 4) × 2 = 12 × 2 = 24

So:
- 3 × (4 × 2) = (3 × 4) × 2
- 3 × 4 = 12 × 2
- 12 = 24

✔ Final answers:
- (3 × 4) × 2
- 3 × 4 = 12 × 2
- 12 = 24

#### 5. Word Problem

> A pet store sold 2 birds. They sold 6 times as many turtles as they sold birds. How many turtles did they sell?

- Birds sold: 2
- Turtles = 6 × birds = 6 × 2 = 12

✔ Answer: 12 turtles

Show work:
- 6 × 2 = 12
