How this book is used in our course

Each topic opens with a rules page. A parent reads it with the child, then the child attempts the 25 questions unaided. Mark them, log the score, and work through every wrong answer with the key. Anything under 90% is repeated after a fortnight. The topic is only finished when the cold repeat clears 90%.

Contents

Fourteen chapters: the whole syllabus, turned into the worded problems the exam actually sets.

Four operations, number and sequences, factors and multiples, fractions and decimals, percentages, ratio and proportion, probability, averages and data, measures, date and time, angles and bearings, 2D and 3D shape, algebra and number machines, coordinates and transformations. Every chapter is a page of key rules, then 45 questions in three bands, Beginner, Intermediate and Advanced. A glossary and maths reference closes the book. This is the one the series builds towards.

Chapter 1 · Key rules

The rules that every worded problem is built from, including the ones no textbook writes down.

BIDMAS and equal rank, working backwards, same units first, fraction of an amount, best buy. Then the rules that lose marks because nobody teaches them: remainders ("how many boxes are needed?" rounds up), sum and difference (larger = (total + difference) ÷ 2), and two prices, one total (suppose every item is the dearer kind, divide the overspend by the difference). A facts table of squares, cubes, triangular numbers and roots sits underneath.

Chapter 1 · Questions

Forty-five problems per chapter, banded Beginner, Intermediate and Advanced.

Questions 1 to 15 are Beginner: a football and boots, a number pyramid, passengers on and off a train, a cinema adding rows, eight bikes for £1452 and the price of three. Each one needs a decision about which operation, and in what order, before any arithmetic. Working space beside every question and an answer line, because in the exam the method is what earns the marks.

Chapter 6 · Intermediate

The language of the exam: "impossible, unlikely, even chance, likely or certain", then fractions in simplest form.

A month with fewer than 31 days. A day beginning with T or S. A prime on a dice. A total of 13 from two dice. A letter from BANANA. Then the same ideas as fractions: a triangle on a grid, a red picture card from 52, a spinner landing on 4 twice, a pupil scoring more than 7 from a frequency table. The question wording is the exam’s own, because that is what a child has to read correctly under time.

Answers & methods

Every answer, every method, fully worked.

Question 2 builds the number pyramid row by row. Question 13 balances the two sides and then checks both: "4 × 6 + 15 = 39 and 7 × 6 − 3 = 39." Question 24: "315 ÷ 12 = 26 remainder 3. 26 pages are full, so the last page has 3 photos." Forty-five methods per chapter, written the way an examiner wants to see the working, so the child learns the layout as well as the answer.
