What's on this sheet

10% of 200 is 20, and that single fact is a lever for most of the page. 20% is double it, 5% is half of it, 30% is three of them. A child who reaches for ten percent first can do most of these in their head, and one who reaches for a calculator learns nothing about the size of the answer.

Why this sheet works

The other route is the fraction: 25% is a quarter, 50% is a half, 75% is three quarters. Both routes are worth having, because which is faster depends entirely on the numbers — a quarter of 84 is easier as a fraction, and 30% of 90 is easier as three tens.

How this one works

One question from this sheet, worked through a step at a time.

10% of 200

1%of200=2
2×10=20
  1. Find one percent first — that is one hundredth of 200, which is 2.
  2. 10% is 10 of those, so multiply: 2 × 10 = 20. So 10% of 200 is 20.
