Adding Subtracting Word Problems
1 Addition Word Problem
Exercise 1
Sarah has 5 apples. Her mom gives her 3 more apples. How many apples does Sarah have now?
Definition:

Word problem: A mathematical problem presented in a real-life context using words

Solution method:
  1. Identify the numbers in the problem (5 and 3)
  2. Identify what operation is needed (addition)
  3. Set up the equation (5 + 3)
  4. Solve the equation (5 + 3 = 8)
Initial amount
\(5\)
Added amount
\(3\)
Total
\(5 + 3 = 8\)
Step 1: Identify the numbers

Sarah starts with 5 apples and gets 3 more

Step 2: Determine the operation

She gets MORE apples, so we add

Step 3: Set up the equation

5 + 3 = ?

Step 4: Solve the equation

5 + 3 = 8

\(5 + 3 = 8\) apples
Final answer:

Sarah has 8 apples now

Applied rules:

• Problem solving: Identify key information in word problems

• Addition: Combine quantities to find totals

• Units: Include the correct units in your answer

2 Subtraction Word Problem
Exercise 2
Tom had 8 cookies. He ate 3 cookies. How many cookies does Tom have left?
Definition:

Subtraction: Taking away one quantity from another to find the difference

Initial amount
\(8\)
Amount taken away
\(3\)
Remaining
\(8 - 3 = 5\)
Step 1: Identify the numbers

Tom starts with 8 cookies and eats 3

Step 2: Determine the operation

He TAKES AWAY cookies, so we subtract

Step 3: Set up the equation

8 - 3 = ?

Step 4: Solve the equation

8 - 3 = 5

\(8 - 3 = 5\) cookies
Final answer:

Tom has 5 cookies left

Applied rules:

• Subtraction: Find what remains after taking away

• Problem solving: Look for clue words like "left", "remaining"

• Verification: Check that the answer makes sense

3 Mixed Operations
Exercise 3
Emma had 6 stickers. She found 4 more stickers. Then she gave 2 stickers to her friend. How many stickers does Emma have now?
Definition:

Multi-step problem: A problem requiring multiple operations to solve

Start with
\(6\)
Add 4
\(6 + 4 = 10\)
Subtract 2
\(10 - 2 = 8\)
Step 1: Identify the first action

Emma starts with 6 stickers and finds 4 more (addition)

Step 2: Solve first operation

6 + 4 = 10 stickers

Step 3: Identify the second action

Then she gives away 2 stickers (subtraction)

Step 4: Solve final operation

10 - 2 = 8 stickers

\(6 + 4 - 2 = 8\) stickers
Final answer:

Emma has 8 stickers now

Applied rules:

• Multi-step problems: Solve one operation at a time

• Order of operations: Follow the sequence of events

• Verification: Check that each step makes sense

4 Addition Context
Exercise 4
There are 7 birds on a tree. 5 more birds fly to the tree. How many birds are on the tree now?
Definition:

Context clues: Information in the problem that helps determine the operation needed

Initial birds
\(7\)
Birds added
\(5\)
Total birds
\(7 + 5 = 12\)
Step 1: Identify the numbers

There were 7 birds and 5 more came

Step 2: Determine the operation

More birds CAME to the tree, so we add

Step 3: Set up the equation

7 + 5 = ?

Step 4: Solve the equation

7 + 5 = 12

\(7 + 5 = 12\) birds
Final answer:

There are 12 birds on the tree now

Applied rules:

• Context clues: "more" indicates addition

• Problem solving: Identify key information

• Verification: Check if the answer is reasonable

5 Subtraction Context
Exercise 5
Jake had 10 marbles. He lost 4 marbles. How many marbles does Jake have now?
Definition:

Change problems: Problems involving an initial amount, a change, and a final amount

Initial marbles
\(10\)
Marbles lost
\(4\)
Remaining marbles
\(10 - 4 = 6\)
Step 1: Identify the numbers

Jake started with 10 marbles and lost 4

Step 2: Determine the operation

He LOST marbles, so we subtract

Step 3: Set up the equation

10 - 4 = ?

Step 4: Solve the equation

10 - 4 = 6

\(10 - 4 = 6\) marbles
Final answer:

Jake has 6 marbles now

Applied rules:

• Change problems: Initial - Change = Final

• Subtraction: Find what remains after taking away

• Context clues: "lost" indicates subtraction

6 Multi-step Problem
Exercise 6
Lily had 9 crayons. She bought 3 more crayons. Then she gave 2 crayons to her sister. How many crayons does Lily have now?
Definition:

Sequence of operations: Problems requiring multiple steps following a specific order

Start with
\(9\)
Add 3
\(9 + 3 = 12\)
Subtract 2
\(12 - 2 = 10\)
Step 1: Identify the first action

Lily starts with 9 crayons and buys 3 more (addition)

Step 2: Solve first operation

9 + 3 = 12 crayons

Step 3: Identify the second action

Then she gives away 2 crayons (subtraction)

Step 4: Solve final operation

12 - 2 = 10 crayons

\(9 + 3 - 2 = 10\) crayons
Final answer:

Lily has 10 crayons now

Applied rules:

• Multi-step problems: Solve one operation at a time

• Order of operations: Follow the sequence of events

• Verification: Check that each step makes sense

Summary: Adding Subtracting Word Problems
Complete Summary and Study Guide

This section provides a comprehensive overview of adding and subtracting word problems, including definitions, methods, strategies, and key concepts for 1st grade students.

Definitions

Word Problem: A mathematical problem presented in a real-life context using words.

Addition: Combining quantities to find totals.

Subtraction: Taking away one quantity from another to find the difference.

Context Clues: Words that indicate which operation to use.

Core Rules

• Addition: Look for words like "more," "added," "total," "altogether"

• Subtraction: Look for words like "less," "took," "left," "remaining"

• Multi-step problems: Solve one operation at a time

• Always include the correct units in your answer

Problem-Solving Steps

1. Read the problem carefully

2. Identify the numbers involved

3. Determine the operation needed

4. Set up the equation

5. Solve the equation

6. Check if the answer makes sense

Examples

Addition: "Sarah has 5 apples. Gets 3 more. Total?" → 5 + 3 = 8

Subtraction: "Tom had 8 cookies. Ate 3. Left?" → 8 - 3 = 5

Multi-step: "Emma had 6, found 4, gave 2. Now?" → 6 + 4 - 2 = 8

All follow the same problem-solving process.

Tips & Tricks

• Draw pictures to visualize the problem

• Look for clue words that indicate the operation

• For multi-step problems, solve one at a time

• Always check if your answer makes sense in the context

Common Mistakes

• Choosing the wrong operation (add vs. subtract)

• Missing numbers in the problem

• Forgetting units in the answer

• Not following the sequence in multi-step problems

Questions & Answers

Question: How do I know when to add and when to subtract in word problems? Sometimes I get mixed up.

Answer: Great question! Here are the clue words to look for:

Addition words: "more," "added," "total," "altogether," "in all," "combined," "gets," "finds," "buys"

Subtraction words: "left," "remaining," "takes away," "loses," "eats," "gives," "less," "fewer"

For example:

  • "Sarah gets 3 more apples" → ADDITION (she has MORE)
  • "Tom has 8 cookies and eats 3" → SUBTRACTION (he has FEWER)

Also think about what's happening: if something is being added or joined together, it's addition. If something is being taken away or separated, it's subtraction.

When in doubt, draw a picture to help visualize what's happening!

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

Answer: Multi-step problems can be challenging! Here are effective strategies:

  • Read slowly: Have your child read the problem multiple times
  • Highlight actions: Circle or underline each action that happens
  • Draw pictures: Visualize each step separately
  • Solve one at a time: Complete the first operation before moving to the next
  • Check progress: Ask "Does this answer make sense?" after each step

For example, in "Emma had 6 crayons, bought 3 more, then gave 2 away":

  1. First: 6 + 3 = 9 crayons (after buying)
  2. Second: 9 - 2 = 7 crayons (after giving away)

Practice with simple multi-step problems first, then gradually increase complexity. Consistent practice will build confidence!

Question: Do I always have to write the number sentence? Can't I just count in my head?

Answer: That's a great question! Writing the number sentence is really helpful, even if you can count in your head. Here's why:

  • It helps you organize your thinking
  • You can check your work more easily
  • It prepares you for harder problems later
  • Teachers can see how you solved the problem

For example, if the problem is "Sarah has 5 apples and gets 3 more," writing "5 + 3 = 8" helps you remember what you did.

As you get older and the problems get harder, writing number sentences becomes even more important!

It's like showing your work - it helps everyone understand how you got your answer.

Even if you solve it in your head, writing the number sentence is good practice!
