📏 Part 1: Conversion Practice

1. Convert these measurements. Show your working in the boxes below:

a) 3500 metres = _________ kilometres

b) 6.8 kilometres = _________ metres

c) 750 metres = _________ kilometres

2. Circle the correct answer for each conversion:

4200 metres =

4.2 kilometres

42 kilometres

0.42 kilometres

2.5 kilometres =

250 metres

2500 metres

25000 metres

🧮 Part 2: Multi-Step Problem Solving

3. Sarah is training for a race. On Monday she ran 2.4 kilometres. On Tuesday she ran 1800 metres. How many metres did she run in total over both days?

Answer: _________ metres

4. A running track is 400 metres long. How many complete laps would you need to run to cover at least 1.5 kilometres? Explain your reasoning.

Answer: _________ laps

5. Challenge: A school has three playing fields. Field A is 0.8 km long, Field B is 650 metres long, and Field C is 1200 metres long. If you walked around the perimeter of all three fields, would you walk more or less than 3 kilometres? Show your calculations.

Answer: More / Less than 3km (circle one)

💭 Part 3: Reasoning and Explanation

6. Jake says: "To convert 4500 metres to kilometres, I just remove three zeros, so the answer is 4.5 kilometres." Is Jake's method correct? Explain why his method works or why it doesn't work. What is the proper mathematical method?

7. Estimation Challenge: Without calculating exactly, estimate which measurement is closest to 1 kilometre. Explain your reasoning.

850 metres

1150 metres

1450 metres

Explain your reasoning:

8. Create your own word problem that requires converting between metres and kilometres, then solve it:
