Students can cut out the math vocabulary words at the bottom and sort them into the correct addition or subtraction column.

The image you've uploaded is a "Addition and Subtraction Key Word Sorting" worksheet designed to help students identify and categorize key words that signal whether a word problem involves addition or subtraction.

🔍 Task Description:

Students are asked to:
- Cut out the given words.
- Sort them into two columns:
- Addition Key Words (+)
- Subtraction Key Words (−)

✔ Step-by-step Solution:

Let’s go through each word and determine whether it belongs in the Addition or Subtraction column based on common math vocabulary cues.

#### 🟩 Addition Key Words (indicate combining, increasing, total):
These words suggest putting things together or finding a total.

- total → Yes (e.g., "What is the total of 5 and 3?")
- join → Yes (e.g., "Sarah joined 2 more friends")
- increase → Yes (e.g., "The number increased by 4")
- combined → Yes (e.g., "They combined their marbles")
- more → Yes (e.g., "5 more than 7")
- plus → Yes (e.g., "5 plus 3")
- sum → Yes (e.g., "What is the sum of 6 and 9?")
- both → Yes (e.g., "Both groups had 10 people")
- add → Yes (e.g., "Add 8 and 2")
- altogether → Yes (e.g., "How many altogether?")

✔ Addition Column:
> total, join, increase, combined, more, plus, sum, both, add, altogether

#### 🔴 Subtraction Key Words (indicate taking away, decreasing, difference):
These words suggest removing, comparing, or finding how much is left.

- less → Yes (e.g., "5 less than 10")
- take away → Yes (e.g., "Take away 3 from 8")
- decrease → Yes (e.g., "The value decreased by 2")
- subtract → Yes (e.g., "Subtract 4 from 9")
- difference → Yes (e.g., "What is the difference between 10 and 6?")
- take → Yes (e.g., "Take 2 apples")
- fewer → Yes (e.g., "She has fewer toys")
- left → Yes (e.g., "How many are left?")
- how many more → Wait! This one is tricky. Let's analyze.

➡️ "How many more?"
This phrase is used when comparing two quantities to find the difference. It usually requires subtraction (e.g., "How many more apples does John have than Mary?"). So even though it sounds like addition, it's actually asking for the difference, so it goes under Subtraction.

✔ Subtraction Column:
> less, take away, decrease, subtract, difference, take, fewer, left, how many more

🧠 Final Answer:

#### ✔ Addition Key Words:
- total
- join
- increase
- combined
- more
- plus
- sum
- both
- add
- altogether

#### ✘ Subtraction Key Words:
- less
- take away
- decrease
- subtract
- difference
- take
- fewer
- left
- how many more

💡 Tips for Students:

- Addition words often involve joining, combining, increasing, or totaling.
- Subtraction words often involve taking away, decreasing, comparing, or finding differences.
- Words like "how many more" may seem confusing but always require subtraction.
