🔁 Part 1: Converting Metric Units

We need to convert between kilometers (km), meters (m), centimeters (cm), and millimeters (mm).
Use these conversion factors:

- 1 km = 1000 m
- 1 m = 100 cm
- 1 cm = 10 mm

---

#### Conversions:

1) 5 km = ____ m
→ 5 × 1000 = 5000 m

2) 600 cm = ____ m
→ 600 ÷ 100 = 6 m

3) 8 cm = ____ mm
→ 8 × 10 = 80 mm

4) ____ km = 4000 m
→ 4000 ÷ 1000 = 4 km

5) ____ m = 900 cm
→ 900 ÷ 100 = 9 m

6) 120 mm = ____ cm
→ 120 ÷ 10 = 12 cm

7) 7 km = ____ m
→ 7 × 1000 = 7000 m

8) 14 cm = ____ mm
→ 14 × 10 = 140 mm

9) 12 m = ____ cm
→ 12 × 100 = 1200 cm

10) ____ km = 13,000 m
→ 13,000 ÷ 1000 = 13 km

11) ____ cm = 130 mm
→ 130 ÷ 10 = 13 cm

12) 1400 cm = ____ m
→ 1400 ÷ 100 = 14 m

🟨 Part 2: Which is the most? Circle the largest amount in each box

We’ll convert all options to the same unit (preferably meters) and compare.

---

Box 1:
- 100 m → 100 m
- 1 km → 1000 m
- 1000 cm → 1000 ÷ 100 = 10 m
→ Largest: 1 km ✔ (already circled)

---

Box 2:
- 3 km = 3000 m
- 2850 m → 2850 m
- 5000 cm = 5000 ÷ 100 = 50 m
→ Compare: 3000 m, 2850 m, 50 m → Largest: 3 km

✔ Circle: 3 km

---

Box 3:
- 380 cm = 3.8 m
- 4000 mm = 4000 ÷ 1000 = 4 m
- 3 m = 3 m
→ Compare: 3.8 m, 4 m, 3 m → Largest: 4000 mm

✔ Circle: 4000 mm

---

Box 4:
- 9020 m → 9020 m
- 20,000 cm = 20,000 ÷ 100 = 200 m
- 9 km = 9000 m
→ Compare: 9020 m, 200 m, 9000 m → Largest: 9020 m

✔ Circle: 9020 m

---

🔍 Part 3: Use >, <, or = to compare amounts

We'll convert both sides to the same unit (usually meters or centimeters) and compare.

---

1) 1200 m ___ 1 km
→ 1 km = 1000 m
→ 1200 > 1000 → >

2) 620 cm ___ 7 m
→ 7 m = 700 cm
→ 620 < 700 → <

3) 8 m ___ 750 cm
→ 8 m = 800 cm
→ 800 > 750 → >

4) 82 mm ___ 7 cm
→ 7 cm = 70 mm
→ 82 > 70 → >

5) 45 mm ___ 5 cm
→ 5 cm = 50 mm
→ 45 < 50 → <

6) 1300 cm ___ 13 m
→ 13 m = 1300 cm
→ 1300 = 1300 → =

7) 900 m ___ 9 km
→ 9 km = 9000 m
→ 900 < 9000 → <

8) 3 ½ km ___ 3080 m
→ 3 ½ km = 3.5 km = 3500 m
→ 3500 > 3080 → >

9) 12 cm ___ 120 mm
→ 12 cm = 120 mm
→ 120 = 120 → =

10) 425 cm ___ 4 ½ m
→ 4 ½ m = 4.5 m = 450 cm
→ 425 < 450 → <
