Tips
- Show the working, even when the answer seems obvious; it makes mistakes easy to spot.
- Check each answer: put it back into an equation, or estimate before working out.
- Start with the easier setting and move up once most answers are right.
- Mix one older sheet into each week so earlier skills stay fresh.
Worked example
3.5 m to cm: 1 m = 100 cm, so 3.5 × 100 = 350 cm. 2,500 g to kg: 1 kg = 1,000 g, so 2,500 ÷ 1,000 = 2.5 kg.
Common mistakes
Multiplying when you should divide. Going to a smaller unit gives a bigger number.
Moving the decimal point the wrong number of places.
