🎯 Learning Objectives

I can:

• Convert between metric units using powers of 10

• Multiply and divide by 10, 100, and 1,000 to change metric units

• Recognize patterns in metric conversions

• Solve real-world problems using metric conversions

📚 Part 1: Multiple Choice

🔢 Part 2: Direct Conversions

a) 2.5 kilometers = ________ meters

b) 750 milliliters = ________ liters

c) 4,200 grams = ________ kilograms

d) 85 centimeters = ________ meters

1 meter = 10 decimeters = 100 centimeters = ________ millimeters

Convert 6.8 liters to milliliters:

📝 Part 3: Word Problems & Extension

📋 Answer Key (Teacher Use)

1. B - Multiply by 100

2. B - 3.5 kg

3. B - 3 places to the left

4. B - Millimeters to meters

5. a) 2,500 m b) 0.75 L c) 4.2 kg d) 0.85 m

6. 1,000 millimeters

7. 6.8 × 1,000 = 6,800 mL

8. 2.5 L = 2,500 mL ÷ 5 = 500 mL per glass

9. 250 g × 4 = 1,000 g = 1 kg

10. 3.2 km = 3,200 m; 3,200 m + 1,500 m = 4,700 m total

11. 45,000 L - 12,500 L = 32,500 L = 32.5 kL

12. 1.2 kg = 1,200 g; 1,200 g + 800 g + 350 g = 2,350 g total

Success Criteria: Students can correctly convert between metric units and explain the relationship between powers of 10 and metric conversions.
