## Part 1: Converting Metric Units – Fill in the Blanks

We’ll use these key conversions:
- 1 km = 1000 m
- 1 m = 100 cm
- 1 cm = 10 mm

So:
- km → m: multiply by 1000
- m → km: divide by 1000
- m → cm: multiply by 100
- cm → m: divide by 100
- cm → mm: multiply by 10
- mm → cm: divide by 10

---

Solutions:

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 need to convert all measurements in each column to the same unit (let’s use meters) to compare.

---

Box 1: 100 m, 1 km, 1000 cm

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

✔ Largest: 1 km (1000 m) — already circled correctly.

---

Box 2: 3 km, 2850 m, 5000 cm

- 3 km = 3 × 1000 = 3000 m
- 2850 m = 2850 m
- 5000 cm = 5000 ÷ 100 = 50 m

✔ Largest: 3 km (3000 m)

---

Box 3: 380 cm, 4000 mm, 3 m

- 380 cm = 380 ÷ 100 = 3.8 m
- 4000 mm = 4000 ÷ 1000 = 4 m (since 1000 mm = 1 m)
- 3 m = 3 m

✔ Largest: 4000 mm (4 m)

---

Box 4: 9020 m, 20,000 cm, 9 km

- 9020 m = 9020 m
- 20,000 cm = 20,000 ÷ 100 = 200 m
- 9 km = 9 × 1000 = 9000 m

✔ Largest: 9020 m

---

✔ Answers for Part 2 (circle these):
- Box 1: 1 km ✔ (already done)
- Box 2: 3 km
- Box 3: 4000 mm
- Box 4: 9020 m

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

Again, convert both sides to the same unit (we'll use meters or centimeters as needed).

---

1) 1200 m ___ 1 km

- 1 km = 1000 m
- 1200 m > 1000 m → >

✔ Answer: >

---

2) 620 cm ___ 7 m

- 7 m = 700 cm
- 620 cm < 700 cm → <

✔ Answer: <

---

3) 8 m ___ 750 cm

- 8 m = 800 cm
- 800 cm > 750 cm → >

✔ Answer: >

---

4) 82 mm ___ 7 cm

- 7 cm = 70 mm
- 82 mm > 70 mm → >

✔ Answer: >

---

5) 45 mm ___ 5 cm

- 5 cm = 50 mm
- 45 mm < 50 mm → <

✔ Answer: <

---

6) 1300 cm ___ 13 m

- 13 m = 1300 cm → =

✔ Answer: =

---

7) 900 m ___ 9 km

- 9 km = 9000 m
- 900 m < 9000 m → <

✔ Answer: <

---

8) 3 ½ km ___ 3080 m

- 3 ½ km = 3.5 km = 3500 m
- 3500 m > 3080 m → >

✔ Answer: >

---

9) 12 cm ___ 120 mm

- 12 cm = 120 mm → =

✔ Answer: =

---

10) 425 cm ___ 4 ½ m

- 4 ½ m = 4.5 m = 450 cm
- 425 cm < 450 cm → <

✔ Answer: <
