Solution: Exercises 1 to 3
1 Length Comparison
Exercise 1
Anna's pencil is 6 inches long. Ben's pencil is 4 inches long. How much longer is Anna's pencil than Ben's?
Problem Context:
Anna and Ben want to compare their pencil lengths to see who has the longer pencil.
Key Information:

Anna's pencil: 6 inches

Ben's pencil: 4 inches

Question: How much longer is Anna's pencil?

Solution Method:

This is a comparison problem. We need to find the difference between two lengths. We subtract the shorter length from the longer length.

Step 1: Identify the longer and shorter lengths

Longer: 6 inches (Anna's pencil)

Shorter: 4 inches (Ben's pencil)

Step 2: Set up the subtraction

Longer - Shorter = Difference

6 - 4 = ?

Step 3: Calculate the difference

6 - 4 = 2

Step 4: Write the answer with units

Anna's pencil is 2 inches longer than Ben's pencil.

Anna's pencil is 2 inches longer than Ben's.
Final Answer:

Anna's pencil is 2 inches longer than Ben's pencil.

Applied Rules:

• Comparison Rule: To find how much longer, subtract the shorter from the longer

• Subtraction Rule: 6 - 4 = 2

• Unit Consistency: Both measurements are in inches

Key Point to Remember:
When comparing measurements, always subtract the smaller number from the larger number to find the difference.
2 Weight Addition
Exercise 2
Mom bought 3 pounds of apples and 2 pounds of oranges. How many pounds of fruit did she buy altogether?
Problem Context:
Mom wants to know the total weight of fruit she purchased for the week.
Key Information:

Apples: 3 pounds

Oranges: 2 pounds

Question: Total pounds of fruit?

Solution Method:

This is an addition problem. We need to combine two weights to find the total. We add the weights together.

Step 1: Identify the weights to add

Apples: 3 pounds

Oranges: 2 pounds

Step 2: Set up the addition

Weight of apples + Weight of oranges = Total weight

3 + 2 = ?

Step 3: Calculate the total

3 + 2 = 5

Step 4: Write the answer with units

Mom bought 5 pounds of fruit altogether.

Mom bought 5 pounds of fruit altogether.
Final Answer:

Mom bought 5 pounds of fruit altogether.

Applied Rules:

• Addition Rule: To find total, add the parts together

• Addition Rule: 3 + 2 = 5

• Unit Consistency: Both measurements are in pounds

Key Point to Remember:
When finding a total, always add the individual amounts together.
3 Capacity Subtraction
Exercise 3
A pitcher had 8 cups of juice. After serving some to guests, there were 3 cups left. How many cups of juice were served?
Problem Context:
The host wants to know how much juice was consumed by guests during the party.
Key Information:

Started with: 8 cups

Left over: 3 cups

Question: How many cups were served?

Solution Method:

This is a subtraction problem. We need to find what was taken away. We subtract the remaining amount from the starting amount.

Step 1: Identify the starting and remaining amounts

Starting: 8 cups

Remaining: 3 cups

Step 2: Set up the subtraction

Starting - Remaining = Amount served

8 - 3 = ?

Step 3: Calculate the amount served

8 - 3 = 5

Step 4: Write the answer with units

5 cups of juice were served to guests.

5 cups of juice were served.
Final Answer:

5 cups of juice were served to guests.

Applied Rules:

• Subtraction Rule: To find what was taken, subtract remaining from starting amount

• Subtraction Rule: 8 - 3 = 5

• Unit Consistency: All measurements are in cups

Key Point to Remember:
When finding how much was taken away, subtract the remaining amount from the original amount.
Solution: Exercises 4 to 5
4 Time Comparison
Exercise 4
Sarah took 15 minutes to walk to school. Her brother took 20 minutes to walk to school. How much longer did it take her brother?
Problem Context:
Sarah and her brother want to compare how long their walks to school take.
Key Information:

Sarah's time: 15 minutes

Brother's time: 20 minutes

Question: How much longer did it take her brother?

Solution Method:

This is a comparison problem. We need to find the difference between two times. We subtract the shorter time from the longer time.

Step 1: Identify the longer and shorter times

Longer: 20 minutes (brother)

Shorter: 15 minutes (Sarah)

Step 2: Set up the subtraction

Longer - Shorter = Difference

20 - 15 = ?

Step 3: Calculate the difference

20 - 15 = 5

Step 4: Write the answer with units

It took her brother 5 minutes longer to walk to school.

Her brother took 5 minutes longer.
Final Answer:

It took her brother 5 minutes longer to walk to school.

Applied Rules:

• Comparison Rule: To find how much longer, subtract the shorter from the longer

• Subtraction Rule: 20 - 15 = 5

• Unit Consistency: Both measurements are in minutes

Key Point to Remember:
Time comparisons work the same way as length comparisons - subtract the smaller time from the larger time.
5 Mixed Measurement Problem
Exercise 5
A rope is 12 feet long. If 5 feet are cut off to tie a package, how long is the remaining piece of rope?
Problem Context:
Someone needs to cut part of a rope for wrapping a gift and wants to know how much rope will be left.
Key Information:

Original length: 12 feet

Cut off: 5 feet

Question: How long is the remaining piece?

Solution Method:

This is a subtraction problem. We need to find what remains after cutting off a piece. We subtract the cut-off amount from the original amount.

Step 1: Identify the original and cut-off amounts

Original: 12 feet

Cut off: 5 feet

Step 2: Set up the subtraction

Original - Cut off = Remaining

12 - 5 = ?

Step 3: Calculate the remaining length

12 - 5 = 7

Step 4: Write the answer with units

The remaining piece of rope is 7 feet long.

The remaining rope is 7 feet long.
Final Answer:

The remaining piece of rope is 7 feet long.

Applied Rules:

• Subtraction Rule: To find remaining amount, subtract what was taken from original

• Subtraction Rule: 12 - 5 = 7

• Unit Consistency: All measurements are in feet

Key Point to Remember:
When something is removed or used, subtract to find what remains.

Questions & Answers

Question: How do I know if I should add or subtract in a measurement problem?

Answer: Look for key words and situations:

  • Add when: combining amounts, finding totals, putting things together ("altogether", "total", "sum", "combined")
  • Subtract when: taking away, finding differences, finding what's left ("left", "remaining", "difference", "how much more", "how much less")

Ask yourself: "Am I putting things together or taking something away?" If you're combining, add. If you're removing or comparing, subtract.

Question: My child struggles with word problems. How can I help them understand what the problem is asking?

Answer: Try these strategies:

  • Read together: Read the problem multiple times slowly
  • Visualize: Have your child draw a picture or act out the situation
  • Highlight key information: Circle numbers and underline what's being asked
  • Simplify: Remove extra words and focus on the math part

Start with simple problems and gradually increase difficulty. Practice regularly with real-life examples like cooking, shopping, or measuring household items.

Question: What if I forget to include the units in my answer? Does it matter?

Answer: Yes, including units is very important! Numbers without units don't tell the whole story. For example:

  • If your answer is "5" but the problem is about length, is it 5 inches, 5 feet, or 5 miles?
  • Without units, your answer could mean anything!
  • Always include the unit (inches, pounds, cups, minutes) in your final answer.

Think of units as the "language" that tells what kind of measurement you're talking about.
