📚 Part 1: Multiple Choice & Key Definitions

WALT: We are learning to differentiate between variables and constants in algebra.

Success criteria: I can identify examples of variables and constants and choose which expressions contain both.

1. Which of the following is a variable?

$10

12°C

2. In the expression 4y + 9, which part is the constant?

3. Check all that are examples of a constant (fixed value):

20°C

3 kilometres

4. Which expression contains both a variable and a constant?

✏️ Part 2: Short Answers & Matching

Differentiation: Use colour-coding (variables in blue, constants in red), peer support or manipulatives if helpful. Dyslexia-friendly options: short sentences and high-contrast printing.

5. For the expression 3a − 2, write the variable and the constant:

Variable: _________ Constant: _________

6. For the expression 4y + 9, write the variable and the constant:

Variable: _________ Constant: _________

7. Match each item on the left with the correct label on the right (draw a line):

A. x

B. 7

C. 2n + 5

D. 4z

1 Variable

2 Constant

3 Both (variable and constant)

8. Extension: Create your own algebraic expression that includes a variable and a constant. Then explain a real-life context (one sentence) where this expression could be used.
