Total
300g + 200g = 500g
Step 1: Identify what's given

2 apples at 150g each, 1 banana at 200g.

Step 2: Calculate apple weight

2 apples × 150g = 300g.

Step 3: Add banana weight

300g + 200g = 500g.

Step 4: State the answer

The total weight is 500g.

2 × 150g + 1 × 200g = 500g
Answer:

The total weight of Sarah's fruits is 500 grams.

Problem-Solving Rules:

2 Comparison Problem
Worksheet Problem 2: Weight Comparison
Tom's backpack weighs 1.5kg and Jane's backpack weighs 1200g. Whose backpack is heavier?
Key Definitions:

Conversion: Changing from one unit to another.

Comparison: Determining which weight is greater or lesser.

Units: Need to be the same for comparison.

Tom's Pack
1.5kg = 1500g
Jane's Pack
1200g
Comparison
1500g > 1200g
Step 1: Convert to same unit

Tom's pack: 1.5kg = 1500g.

Step 2: Compare the numbers

1500g vs 1200g.

Step 3: Determine which is heavier

1500g > 1200g.

Step 4: State the answer

Tom's backpack is heavier.

1500g > 1200g (Tom's pack is heavier)
Answer:

Tom's backpack is heavier than Jane's backpack.

Comparison Rules:

• Convert units: Always convert to the same unit before comparing

• Conversion rule: 1kg = 1000g

• Compare numbers: When units are the same, compare the numbers

• Use symbols: > (greater than), < (less than), = (equal)

3 Subtraction Problem
Worksheet Problem 3: Weight Reduction
A bag of rice originally weighed 5kg. After cooking, 2kg of rice was used. How much rice is left?
Key Definitions:

Subtraction: Taking away one weight from another.

Remainder: What is left after subtraction.

Original weight: The starting weight before reduction.

Original
5kg
Used
2kg
Remaining
3kg
Step 1: Identify original weight

The bag originally weighed 5kg.

Step 2: Identify amount used

2kg of rice was used.

Step 3: Subtract to find remainder

5kg - 2kg = 3kg.

Step 4: State the answer

There are 3kg of rice left.

5kg - 2kg = 3kg remaining
Answer:

There are 3 kilograms of rice left in the bag.

Subtraction Rules:

• Same units required: Both weights must be in the same unit

• Subtract the smaller from larger: Original - Used = Remaining

• Keep the unit: The answer has the same unit as the original

• Check reasonableness: Verify the answer makes sense

Advanced Weight Word Problems
4 Multi-Step Problem
Worksheet Problem 4: Multi-Step Challenge
A farmer harvested 15kg of apples on Monday, 12kg on Tuesday, and 8kg on Wednesday. He sold 20kg to the market. How many kilograms of apples does he have left?
Problem Analysis:

Harvesting: Collecting apples (adding to total).

Selling: Removing apples (subtracting from total).

Multi-step: Requires addition and subtraction.

Total Harvested
15 + 12 + 8 = 35kg
Sold
20kg
Remaining
35 - 20 = 15kg
Step 1: Calculate total harvest

Monday: 15kg + Tuesday: 12kg + Wednesday: 8kg = 35kg.

Step 2: Subtract what was sold

35kg - 20kg = 15kg.

Step 3: State the final answer

The farmer has 15kg of apples left.

Step 4: Verify reasonableness

15kg remaining makes sense after selling 20kg from 35kg.

15kg + 12kg + 8kg - 20kg = 15kg
Answer:

The farmer has 15 kilograms of apples left.

Multi-Step Problem Rules:

• Break into parts: Identify each step needed

• Track units: Keep units consistent throughout

• Check each step: Verify calculations as you go

• Verify final answer: Make sure it's reasonable

5 Balance Scale Problem
Worksheet Problem 5: Balance Scale Reasoning
On a balance scale, 3 oranges balance with 1 apple. If the apple weighs 200g, how much does each orange weigh if they all weigh the same?
Balance Scale Logic:

Balance: When both sides weigh the same.

Division: Sharing a total among equal parts.

Equality: Both sides of the scale are equal.

Left Side
3 oranges
Right Side
1 apple = 200g
Each Orange
200g ÷ 3 ≈ 67g
Step 1: Understand the balance

3 oranges = 1 apple (they balance).

Step 2: Identify the apple's weight

The apple weighs 200g.

Step 3: Calculate total orange weight

3 oranges = 200g.

Step 4: Find weight per orange

200g ÷ 3 = approximately 67g per orange.

3 oranges = 200g → 1 orange ≈ 67g
Answer:

Each orange weighs approximately 67 grams.

Balance Scale Rules:

• Balance means equal: Both sides weigh the same

• Divide equally: When items are identical, divide total weight

• Check reasonableness: Verify the answer makes sense

Questions & Answers

Question: I sometimes get confused about whether to add or subtract in word problems. How can I tell which one to use?

Answer: Great question! Here are clues to help you decide:

  • Add when: You're finding a total, combining, putting together, or getting more
  • Subtract when: You're taking away, using, giving away, or finding what's left
  • Look for key words: "total," "altogether," "combined" (add); "left," "remaining," "used" (subtract)

Example for addition: "Sarah has 200g of apples and gets 150g more" → 200 + 150 = 350g

Example for subtraction: "Tom had 500g of flour and used 200g" → 500 - 200 = 300g left

Practice identifying these patterns in different problems!

Question: My child struggles with multi-step word problems. How can I help them break these down?

Answer: Multi-step problems can be overwhelming! Here's a strategy:

  • Read together: Have your child read the problem aloud
  • Highlight steps: Identify what needs to be done first, second, etc.
  • Draw it out: Visualize the problem with drawings
  • Check each step: Verify calculations before moving to the next

Example breakdown:

Problem: "John bought 3kg of rice, then 2kg more, and gave away 1kg. How much does he have?"

  • Step 1: Bought 3kg + 2kg = 5kg total
  • Step 2: 5kg - 1kg given away = 4kg remaining

Practice with simple multi-step problems first, then gradually increase complexity.

Question: What are effective ways to teach students to convert between grams and kilograms in word problems?

Answer: Conversion in word problems requires clear understanding:

  • Establish the relationship: 1kg = 1000g (always)
  • Identify when conversion is needed: Before comparing or calculating
  • Teach the process: Multiply by 1000 to convert kg to g, divide by 1000 to convert g to kg
  • Practice with real examples: Use familiar objects and weights

Memory aid: "Kilo" means thousand, so 1 kilogram = 1000 grams.

Teaching progression:

  1. Start with simple conversions: 1kg = 1000g
  2. Practice with multiples: 2kg = 2000g
  3. Introduce decimals: 1.5kg = 1500g
  4. Apply in word problems with mixed units

Always emphasize checking that the converted value makes sense (larger number for grams, smaller for kg).
