3 Comparing Weights Worksheet
Exercise 3 - PDF Worksheet
Fill in the blanks with <, >, or = for the PDF worksheet:
2.5 kg ___ 2,400 g
1,500 g ___ 1.5 kg
3 kg ___ 3,500 g
800 g ___ 0.8 kg
Definition:

Comparing Weights: To compare weights in different units, convert both to the same unit before comparing.

Step 1: Convert and compare first pair

2.5 kg = 2,500 g; 2,500 g > 2,400 g
So: 2.5 kg > 2,400 g

Step 2: Convert and compare second pair

1,500 g = 1.5 kg; 1.5 kg = 1.5 kg
So: 1,500 g = 1.5 kg

Step 3: Convert and compare third pair

3 kg = 3,000 g; 3,000 g < 3,500 g
So: 3 kg < 3,500 g

Step 4: Convert and compare fourth pair

0.8 kg = 800 g; 800 g = 800 g
So: 800 g = 0.8 kg

Completed: 2.5kg>2,400g; 1,500g=1.5kg; 3kg<3,500g; 800g=0.8kg
Final answers for PDF worksheet:

2.5 kg > 2,400 g
1,500 g = 1.5 kg
3 kg < 3,500 g
800 g = 0.8 kg

Applied rules:

• Unit Standardization: Convert to the same unit before comparing

• Conversion: Use multiplication or division by 1,000 as needed

Total weight = 1,800 grams + 900 grams = 2,700 grams

Step 3: Verify the calculation

1,800 + 900 = 2,700 ✓

Step 4: State the result

Total weight = 2,700 grams

Total weight: 2,700 g
Final answer for PDF worksheet:

The total weight of the fruits is 2,700 grams.

5 Word Problem Worksheet: Sharing Weight
Exercise 5 - PDF Worksheet
Solve this word problem for the PDF worksheet: A box of chocolates weighs 2.4 kg. If the chocolates are shared equally among 6 children, how many grams of chocolate does each child get? Show your work in the PDF space provided.
Definition:

Weight Division: Dividing a total weight by the number of people or portions to find individual shares.

Step 1: Convert the total weight to grams

2.4 kg = 2.4 × 1,000 = 2,400 grams

Step 2: Divide the total weight by the number of children

Each child gets 400 grams of chocolate

Each child gets 400 g
Final answer for PDF worksheet:

Each child gets 400 grams of chocolate.

Applied rules:

• Conversion: Change kilograms to grams before dividing

• Division: Divide total weight by number of people

• Equal Sharing: Each person gets the same portion

Questions & Answers

Question: My 3rd grade students need PDF worksheets for practicing grams and kilograms. How can I structure these for maximum learning?

Answer: Here are effective structures for PDF worksheets on grams and kilograms:

  • Progressive difficulty: Start with basic conversions, then move to word problems
  • Visual elements: Include pictures of objects with weights
  • Work space: Provide adequate space for showing work
  • Self-check: Include answer boxes for students to fill in

Structure your PDF worksheet with:

  • Clear instructions at the top
  • Examples with worked solutions
  • Practice problems with increasing complexity
  • Space for showing work and final answers

Consider including a conversion chart at the top of the PDF for reference.

Question: My child is struggling with the PDF worksheets on grams and kilograms. What strategies can help them succeed?

Answer: Effective strategies for success with PDF worksheets:

  • Pre-work: Practice with real objects before attempting worksheets
  • Reference sheet: Keep a conversion chart visible while working
  • Step-by-step: Write out each step of the conversion process
  • Verification: Check answers by converting back

Consistent practice with PDF worksheets will build confidence and skill.

Question: I have to fill in the blanks on my PDF worksheet but I'm not sure when to multiply and when to divide when converting?

Answer: Think about which unit is bigger:

  • Kilograms are bigger than grams
  • Going from big to small (kg to g): MULTIPLY by 1,000
  • Going from small to big (g to kg): DIVIDE by 1,000

On your PDF worksheet:

  • 3 kg to grams: 3 × 1,000 = 3,000 g (multiply because going from big to small)
  • 5,000 g to kg: 5,000 ÷ 1,000 = 5 kg (divide because going from small to big)

Remember: More grams equal fewer kilograms because grams are smaller units!

Question: What if I have decimals on my PDF worksheet when converting? Like 2.5 kg to grams?

Answer: When working with decimals on PDF worksheets, the same rules apply:

  • For kg to g: Multiply by 1,000 (move decimal point 3 places to the right)
  • For g to kg: Divide by 1,000 (move decimal point 3 places to the left)

For 2.5 kg to grams on your worksheet:

  • 2.5 × 1,000 = 2,500 grams
  • You can think: 2.5 → 25.0 → 250.0 → 2,500.0
  • Move the decimal point 3 places to the right

More examples for your PDF:

  • 0.75 kg = 750 g (0.750 → 750)
  • 1,250 g = 1.25 kg (1250. → 1.250)

Question: How do I check my answers on the PDF worksheet? Sometimes I'm not sure about my conversions.

Answer: Here are effective ways to check your PDF worksheet answers:

  • Reverse calculation: Convert back to the original unit to see if you get the starting value
  • Reasonableness check: Does your answer make sense? (Fewer kg should equal more g)
  • Factor of 1,000: Check if the numbers differ by a factor of 1,000

Example: If you convert 2.5 kg to 2,500 g on your worksheet:

  • Reverse: 2,500 g ÷ 1,000 = 2.5 kg ✓
  • Reasonable: 2.5 kg is less than 2,500 g ✓
  • Factor: 2,500 ÷ 2.5 = 1,000 ✓

Always double-check by using the reverse operation on your PDF worksheet!
