Ten weeks, built from
the answers they got wrong.

Not a generic practice book. The chapters are generated after the test, from your own child's paper, and they run in the order that unblocks the most work.

1

The test finds the gaps.

Every wrong answer is tagged to a skill and to the misconception that most likely caused it.

2

The gaps are ranked.

Skills that block other skills come first. Fractions before ratio, place value before rounding.

3

Ten chapters are written.

Each one warms up, works an example, then practises. About a week of work per chapter.

A sample chapter

Chapter 1: common denominators.

Generated because question 14 came back as 3/7. Every page below follows from that one answer.

Chapter 1 - page 1 - warm up
What a denominator is counting

Before adding two fractions, both have to be cut into the same size pieces. These five questions check that the idea is there.

1Shade 2/3 of the bar, then shade 1/4 of an identical bar. Are the pieces the same size?
2Write three fractions equal to 1/2.
3Which is larger, 2/3 or 5/8? Explain how you know.

Answers on page 9. Roughly 10 minutes.

Chapter 1 - page 2 - worked example
Adding 2/3 and 1/4

The step that went missing on test day, written out once, slowly.

aTwelve is the smallest number both 3 and 4 divide into.
b2/3 becomes 8/12. 1/4 becomes 3/12.
cNow the pieces match, so add the numerators only: 11/12.
Your turn

One chapter a week

Practice they can
actually do alone.

Each chapter warms up, works one example slowly, then practises the same idea until it is boring. Short enough to finish in a sitting, aimed narrowly enough that finishing it is worth something.

The full ten weeks.

This is Maya's book. Another child sitting the same test gets a different one.

Week 1Common denominatorsFrom question 14. Blocks every fraction skill below it.Priority
Week 2Adding and subtracting fractionsBuilds directly on week 1, same worked pattern.Priority
Week 3Simplifying to lowest termsFrom question 21. A habit gap, so it is short and frequent.Follow on
Week 4Fractions to decimals and backSecure in one direction only.Follow on
Week 5Ratio written three waysRight as a fraction, wrong with a colon.Follow on
Week 6Proportion and scalingDepends on weeks 1 and 5 being solid.Follow on
Week 7Percentages of amountsIntroduced here because the fraction base is now in place.Extension
Week 8Multi-step word problemsEach step was already correct in isolation.Extension
Week 9Mixed reviewEverything from weeks 1 to 8, interleaved deliberately.Extension
Week 10Check yourselfA short paper in the same format as the original test.Extension

A whole term, aimed properly.

Ten chapters that exist because of what your child actually got wrong, rather than what a publisher guessed an average child might.
