Part 1: Subtracting Integers and Decimals

WALT: We Are Learning To subtract positive and negative numbers accurately.

Success criteria: I can use a number line or place-value method, keep track of signs, and check whether my answer is reasonable.

Dyslexia-friendly option: Read each question aloud, cover the other questions, and use squared paper to line up place values.

2. Calculate: −18 − 27 = _________

3. Calculate: −42 − (−15) = _________

4. Calculate: 7.5 − 12.86 = _________

5. Calculate: 35.04 − 8.976 = _________

Part 2: Apply Subtraction

WALT: We Are Learning To apply subtraction to real-life and mathematical situations.

Success criteria: I can identify the numbers needed, choose a suitable method, show my working, and write the correct units.

6. The temperature in Canberra was 6°C in the morning and −3°C overnight. What was the decrease in temperature?

7. A cyclist planned to ride 42.5 kilometres but completed 36.78 kilometres. How many kilometres remained?
