Understanding Word Problem Keywords

What Are Word Problem Keywords?

Word problem keywords are special words that tell us whether to add or subtract in a math problem. These words act like signs that point us in the right direction.

Core Definitions:

Key definitions:

Addition Keywords: Words that signal combining or increasing quantities

Subtraction Keywords: Words that signal taking away or decreasing quantities

Problem Solving Strategy: Identifying keywords to determine the correct mathematical operation

+
ADDITION
• More
• Together
• Total
• Sum
• Altogether
• Combined
• Plus
• Added to
−
SUBTRACTION
• Less
• Fewer
• Left
• Remaining
• Difference
• Take away
• Minus
• Gives
5-Step Problem Solving Method:
  1. Read Carefully: Read the entire problem slowly
  2. Circle Keywords: Find and circle the operation words
  3. Identify Numbers: Find the numbers to work with
  4. Draw Picture: Sketch to visualize the problem
  5. Solve & Check: Do the math and verify your answer
Tip 1: "Together" and "total" almost always mean addition.
Tip 2: "Left" and "remaining" usually mean subtraction.
Tip 3: Ask: "Are we putting things together or taking them away?"
Tip 4: Draw dots or circles to represent objects in the problem.
Common Mistake: Seeing "and" and automatically adding. Look at the question too!
Memory Aid: Addition = Adding more; Subtraction = Taking away.
Solution: Exercises 1 to 3
1 Basic Addition Problem
Exercise 1
Emma has 4 red balloons. Her brother gives her 3 more balloons. How many balloons does Emma have altogether?
1
Keyword Identification: "more" and "altogether" indicate addition
2
Numbers: 4 (original) and 3 (additional)
3
Equation: 4 + 3 = 7
Visual Representation:

Red balloons: ●●●● (4)

More balloons: ●●● (3)

Total: ●●●●●●● (7)

Emma has 7 balloons altogether.
Final answer:

Emma has 7 balloons altogether.

Key Learning:

• "More" means addition: 4 + 3 = 7

• "Altogether" asks for the total

• We combine both groups to find the answer

2 Basic Subtraction Problem
Exercise 2
Jake has 8 toy cars. He gives 3 toy cars to his friend. How many toy cars does Jake have left?
1
Keyword Identification: "gives" and "left" indicate subtraction
2
Numbers: 8 (original) and 3 (given away)
3
Equation: 8 - 3 = 5
Visual Representation:

All cars: ●●●●●●●● (8)

Gone: ❌❌❌ (3)

Remaining: ●●●●● (5)

Jake has 5 toy cars left.
Final answer:

Jake has 5 toy cars left.

Key Learning:

• "Gives" means taking away: 8 - 3 = 5

• "Left" asks for what remains

• We subtract to find the remaining amount

3 Combined Groups Problem
Exercise 3
There are 5 children playing soccer and 4 children playing basketball. How many children are playing sports altogether?
1
Keyword Identification: "altogether" indicates addition
2
Numbers: 5 (soccer) and 4 (basketball)
3
Equation: 5 + 4 = 9
Visual Representation:

Soccer: ⚽⚽⚽⚽⚽ (5)

Basketball: 🏀🏀🏀🏀 (4)

Total: ⚽⚽⚽⚽⚽🏀🏀🏀🏀 (9)

9 children are playing sports altogether.
Final answer:

9 children are playing sports altogether.

Key Learning:

• "Altogether" means combining all groups

• We add different activities to find the total

• Both groups count toward the final answer

Solution: Exercises 4 to 5
4 Subtraction with Context
Exercise 4
Sarah baked 10 cookies. She ate 4 cookies herself. How many cookies are remaining?
1
Keyword Identification: "ate" and "remaining" indicate subtraction
2
Numbers: 10 (baked) and 4 (eaten)
3
Equation: 10 - 4 = 6
Visual Representation:

All cookies: 🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪 (10)

Eaten: ❌❌❌❌ (4)

Remaining: 🍪🍪🍪🍪🍪🍪 (6)

6 cookies are remaining.
Final answer:

6 cookies are remaining.

Key Learning:

• "Ate" means taking away: 10 - 4 = 6

• "Remaining" asks for what's left after subtraction

• The original amount decreases by the amount taken away

5 Multi-step Addition
Exercise 5
On Monday, 6 birds were sitting on a tree. On Tuesday, 3 more birds joined them. How many birds are there altogether?
1
Keyword Identification: "more" and "altogether" indicate addition
2
Numbers: 6 (Monday) and 3 (Tuesday)
3
Equation: 6 + 3 = 9
Visual Representation:

Monday: 🐦🐦🐦🐦🐦🐦 (6)

Tuesday: 🐦🐦🐦 (3)

Total: 🐦🐦🐦🐦🐦🐦🐦🐦🐦 (9)

9 birds are there altogether.
Final answer:

9 birds are there altogether.

Key Learning:

• "More" indicates addition: 6 + 3 = 9

• "Altogether" asks for the combined total

• Time periods don't change the addition principle

Questions & Answers

Question: How can I help my students who struggle with distinguishing between "more" and "left"? They often confuse these keywords.

Answer: This is a very common challenge! Here are effective strategies:

  • Contextual Teaching: "More" means getting extra, "left" means what stays after taking away
  • Physical Demonstration: Use manipulatives - add more cubes vs. remove some and see what remains
  • Act It Out: Have students physically demonstrate scenarios (adding more friends vs. leaving some behind)
  • Memory Phrase: "More = Getting More" and "Left = What Stays"
  • Visual Cues: Use arrows pointing inward for addition, outward for subtraction

Create keyword sorting activities and practice with multiple examples. Repetition with variety helps solidify understanding.

Question: Sometimes I see "and" in problems. Should I always add when I see "and"? Like "I have 2 dogs and 3 cats" - do I add them?

Answer: Great question! "And" connects information, but the operation depends on the question:

  • If the question asks "total" or "altogether": YES, add them (2 + 3 = 5 pets total)
  • If the question asks about just one group: NO, keep them separate
  • Look at the entire sentence to understand what's being asked

Example: "I have 2 dogs and 3 cats. How many pets altogether?" → Add: 2 + 3 = 5

But: "I have 2 dogs and 3 cats. How many cats?" → Answer: 3 cats (no addition)

Question: What are some fun ways to practice these keywords at home? My child learns better when engaged in activities.

Answer: Here are engaging home activities:

  • Keyword Scavenger Hunt: Find addition/subtraction words in books or signs
  • Cooking Math: "We need 3 cups and 2 more cups" (addition) or "We used 4 eggs, how many left?" (subtraction)
  • Toy Sorting: Count toys, add more, or take some away while saying keywords aloud
  • Story Creation: Make up stories using keyword phrases
  • Art Projects: Draw pictures showing addition (combining) and subtraction (removing)

Daily practice with real-life scenarios reinforces learning naturally and makes math meaningful!
