1 L = 1,000 mL, 0.5 L = 500 mL, 2 L = 2,000 mL

Step 2: Compare each pair

1,000 mL vs 750 mL → 1 L is greater

500 mL vs 500 mL → They are equal

2,000 mL vs 2,000 mL → They are equal

Step 3: Record the results

Document which is greater or if they are equal

Step 4: Verify with real containers

Use actual containers to confirm your findings

1 L > 750 mL
500 mL = 0.5 L
2 L = 2,000 mL
Final answer:

1 L bottle holds more than 750 mL bottle
500 mL bottle equals 0.5 L bottle
2 L bottle equals 2,000 mL bottle

Applied rules:

• Unit consistency: Convert to same units before comparing

• Verification: Use physical containers to confirm results

• Comparison: Greater than (>), less than (<), or equal (=)

3 Addition Activity
Exercise 3
Pour water from different containers into a large measuring cup and calculate the total volume:
250 mL + 150 mL + 0.5 L = ? mL
1 L + 200 mL + 300 mL = ? L
Use actual containers to verify your calculations.
Definition:

Addition Activity: An exercise that involves combining liquid volumes and calculating the total.

Convert to mL
0.5L→500mL, 1L→1000mL
Calculate
250+150+500=900mL, 1000+200+300=1500mL=1.5L
Step 1: Convert all measurements to the same unit

Convert liters to milliliters: 0.5 L = 500 mL, 1 L = 1,000 mL

Step 2: Add the volumes

250 mL + 150 mL + 500 mL = 900 mL

1,000 mL + 200 mL + 300 mL = 1,500 mL = 1.5 L

Step 3: Pour and measure

Actually pour the liquids into a measuring cup to verify totals

Step 4: Record results

Document calculated vs. measured volumes

250 mL + 150 mL + 0.5 L = 900 mL
1 L + 200 mL + 300 mL = 1.5 L
Final answer:

250 mL + 150 mL + 0.5 L = 900 milliliters
1 L + 200 mL + 300 mL = 1.5 liters

Applied rules:

• Unit consistency: Convert to same units before adding

Convert
1.5 L = 1,500 mL
Divide
1,500 ÷ 6 = 250 mL
Step 1: Convert to the unit you want

1.5 L = 1,500 mL

Actually pour water into 6 containers and measure each

Step 4: Verify equality

Confirm that each container has approximately 250 mL

Each container holds 250 milliliters
Final answer:

Each container will hold 250 milliliters of water

Applied rules:

• Division: Amount per container = Total ÷ Number of containers

• Equal sharing: Division is used when distributing equally

• Verification: Use physical measurement to confirm calculation
