Problem 2: Tom's desk is 60 centimeters long. His bookshelf is 85 centimeters long. How much longer is the bookshelf?
Problem 3: A rope measures 1 meter. How many centimeters is this?
Problem 4: A piece of string is 75 centimeters long. How many meters and centimeters is this?
Problem 5: Sarah walked 2 meters and 30 centimeters. How many centimeters did she walk?
Length conversion: 1 meter = 100 centimeters
- Identify the operation needed (addition, subtraction, conversion)
- Ensure all measurements are in the same unit
- Perform the calculation
- Include the correct unit in your answer
Used: 5 cm
Remaining: 12 - 5 = 7 cm
Answer: 7 cm
Bookshelf: 85 cm
Difference: 85 - 60 = 25 cm
Answer: The bookshelf is 25 cm longer
Answer: 100 cm
Answer: 0 m 75 cm
Answer: 230 cm
• Subtraction: For finding remaining amounts
• Comparison: Compare numbers with same units
• Conversion: 1 meter = 100 centimeters
Problem 2: Which is heavier: 1500 grams or 1 kilogram 300 grams?
Problem 3: Mom bought 3 kilograms of rice. She used 1 kilogram 200 grams. How much rice is left?
Problem 4: A box weighs 2 kilograms 500 grams. How many grams is this?
Problem 5: Tom's backpack weighs 1 kilogram. His brother's weighs 800 grams. Who has the heavier backpack?
Weight conversion: 1 kilogram = 1000 grams
Eaten: 600 g
Remaining: 2000 - 600 = 1400 g = 1 kg 400 g
Answer: 1 kg 400 g
1500 g > 1300 g, so 1500 g is heavier
Answer: 1500 grams is heavier
Used: 1 kg 200 g = 1200 g
Left: 3000 - 1200 = 1800 g = 1 kg 800 g
Answer: 1 kg 800 g
Answer: 2500 g
Brother: 800 g
1000 g > 800 g, so Tom's backpack is heavier
Answer: Tom has the heavier backpack
• Conversion: 1 kg = 1000 g
• Mixed units: Convert to same units before comparing
• Subtraction: For finding remaining amounts
Problem 2: A jug contains 2 liters of juice. Small cups that hold 100 milliliters each are filled. How many cups can be filled?
Problem 3: A container has 3200 milliliters of water. How many liters and milliliters is this?
Problem 4: A tank holds 4 liters. How many 200-milliliter portions can be made?
Problem 5: Sarah drank 1 liter 300 milliliters of water. Tom drank 1100 milliliters. Who drank more?
Capacity conversion: 1 liter = 1000 milliliters
Drunk: 500 mL
Remaining: 1200 - 500 = 700 mL
Answer: 700 mL
Each cup: 100 mL
Number of cups: 2000 ÷ 100 = 20 cups
Answer: 20 cups
Answer: 3 L 200 mL
Portion size: 200 mL
Number of portions: 4000 ÷ 200 = 20 portions
Answer: 20 portions
Tom: 1100 mL
1300 mL > 1100 mL, so Sarah drank more
Answer: Sarah drank more
• Conversion: 1 L = 1000 mL
• Division: For finding how many units fit
• Regrouping: Separate into whole liters and remaining milliliters
Problem 2: Sarah practiced piano for 35 minutes. Tom practiced for 1 hour 10 minutes. How much longer did Tom practice?
Problem 3: A school event lasts 2 hours 45 minutes. How many minutes is this?
Problem 4: A school event starts at 10:30 AM and ends at 12:15 PM. How long did it last?
Problem 5: If lunch starts at 11:30 AM and lasts 30 minutes, when does it end?
Time conversion: 1 hour = 60 minutes
Duration: 1 hour 25 minutes
End: 3:15 + 1:25 = 4:40 PM
Answer: 4:40 PM
Tom: 1 hour 10 minutes = 70 minutes
Difference: 70 - 35 = 35 minutes
Answer: 35 minutes longer
Answer: 165 minutes
Hours: 12 - 10 = 2 hours
Minutes: 15 - 30 = -15 minutes (so subtract 1 hour, add 60 minutes)
Total: 1 hour 45 minutes
Answer: 1 hour 45 minutes
Duration: 30 minutes
End: 11:30 + 0:30 = 12:00 PM
Answer: 12:00 PM
• Time addition: Add hours and minutes separately
• Regrouping: Convert extra minutes to hours
• Conversion: 1 hour = 60 minutes

| Measurement Type | Large Unit | Small Unit | Conversion Factor | Example |
|---|---|---|---|---|
| Length | meter (m) | centimeter (cm) | × 100 | 2 m = 200 cm |
| meter (m) | millimeter (mm) | × 1000 | 1 m = 1000 mm | |
| centimeter (cm) | millimeter (mm) | × 10 | 5 cm = 50 mm | |
| Weight | kilogram (kg) | gram (g) | × 1000 | 3 kg = 3000 g |
| gram (g) | milligram (mg) | × 1000 | 2 g = 2000 mg | |
| Capacity | liter (L) | milliliter (mL) | × 1000 | 4 L = 4000 mL |
| milliliter (mL) | microliter (μL) | × 1000 | 1 mL = 1000 μL |
