🔗 Part 1: Match the Term to Its Definition

Draw a line to match each algebra term on the left to its correct definition on the right.

Variable

Constant

Expression

A fixed number that does not change (e.g., 5 or 10)

A combination of numbers and letters using operations (e.g., 3x + 4)

A letter that represents an unknown or changing number (e.g., x or y)

🔍 Part 2: Identifying Variables and Constants

Look at each expression below. Circle the variable(s) and underline the constant(s).

1. 7 + x

2. 3y – 5

3. 4a + b

4. 2x + 3

5. Which of the following are variables? Tick all that apply.

x

12

a

7

y

✏️ Part 3: Short Answer Questions

6. In your own words, what do you think a variable represents in maths?

7. Can you think of a real-life example where a variable would be useful? (Hint: think about something that can change, like the number of apples in a bag.)

8. Write your own algebraic expression using one variable and one constant. Then describe what your expression could mean.

My expression: _______________________

It means: _______________________________________________

9. Look at this expression: 5 + y — is 5 a variable or a constant? How do you know?

Variable, because it is a letter.

Constant, because it is a fixed number.

I'm not sure yet.
