Worked examples
RookieRead and interpret directly.
How many minutes are in 1 hour?
- 60
- 100
- 30

ProCompare and infer.
Which is LONGER: 1.5 m or 145 cm?
- 1.5 m
- 145 cm
- They are equal
- Cannot tell
Answer: 1.5 m. 1.5 m = 150 cm; 150 > 145.
GuruMulti-step reasoning.
Why does the formula A = L × W give cm² as the unit (not cm)?
- Because we multiply length × length — each in cm — and cm × cm = cm² (square centimetres).
- Because the answer is bigger than length.
- Because two-digit numbers always have squared units.
- Because the question said so.
Answer: Because we multiply length × length — each in cm — and cm × cm = cm² (square centimetres).. Multiplying cm × cm gives cm² — square centimetres — because we're measuring area.
