Bake-off: a fractions and ratio game for the 11+

About Bake-off

Bake-off turns 11+ fractions and ratio into a baking contest. A round is three bakes (cupcakes, bread and a showstopper cake), and each of the 15 recipe steps is one question. The cupcakes lean on adding and subtracting fractions, the bread on multiplying and dividing them, and the showstopper on ratio and proportion; every round covers all three topics.

Each bake ends by proofing the oven: a harder question while the oven timer ticks. Questions get harder after a streak and easier after misses, and no question runs out of time; a quick answer just earns a speed bonus. Once the showstopper is finished, the review gives a score for each topic and explains every trap that caught your child, with the working.

Fractions: Addition and Subtraction

Questions ask children to add and take away fractions with the same or different denominators, work with mixed numbers and find fractions of an hour. It builds the habit of finding a common denominator first, e.g. 1/4 + 1/3 = 3/12 + 4/12 = 7/12. Learn the topic →

Fractions: Multiplication and Division

Questions ask for a fraction of a fraction or of an amount, a fraction times a whole number and dividing by a fraction, including scaling a recipe. It builds the rules behind them: “of” means multiply, and 3 ÷ 1/4 = 12 because each whole holds four quarters. Learn the topic →

Ratio and Proportion

Questions ask children to simplify ratios, share an amount in a ratio, scale recipes and use map scales. It builds the habit of finding one part first, e.g. sharing 20 in the ratio 3 : 2 makes one part 4, so the shares are 12 and 8. Learn the topic →
