Your next step
This guide prepares your child for the GL-style paper. The 11+ Maths Mastery Series goes further: 12 books that teach every topic from the first term of Year 4, in order, so nothing is left to the final months.
How this book is used in our course
One concept at a time. Read the strategy page together, talk through the two worked examples, then do Set A and Set B. Mark with the answers at the back and record the score. Below 18 out of 20, revisit the strategy page and try again; a concept is finished when it reaches 90% twice. Then sit the two mock papers to time.

What's inside Definitive Guide 2
Five real pages from the book, so you can see exactly what your child will work from. All 12 sample pages are in the viewer.

Fifty questions, fifty minutes, no calculator: the paper explained before a single question is set.
What the GL-style maths paper covers, why the second half is harder and wordier, and the pacing our tutors teach: questions 1 to 25 in about 10 to 15 minutes, banking time for the multi-step problems. Then how the guide works: a strategy page for every concept, two worked examples, 20 practice questions, two full mock papers. Every question original, written in the GL style.

What the examiner is really testing, the method, and the traps GL sets.
Place value, rounding and negative numbers: how often it appears in the practice papers, what the question is really checking, a step-by-step method and the traps that catch children out, like zeros in the middle of a number and temperatures below zero. Every one of the 17 concepts opens the same way, so a child learns how to approach a question type, not just how to answer one.

Twenty questions per concept: Set A builds the method, Set B is at the 90% Standard.
Five-option multiple choice, exactly as the paper sets it. Eighteen out of twenty masters the concept. Anything lower means another pass before moving on, so the gaps close before the mock papers, not after them.

Two full mock papers: 50 questions, 50 minutes, with the target pace printed at the top.
Questions 1 to 25 in about 15 minutes, 26 to 50 in the rest, a few minutes left to check. Each paper mirrors the real paper's length, mix and timing, with its own answer sheet, so the first time a child sits a full GL-style paper is at the kitchen table, not in the exam hall.

Every question, every answer, full working, and the classic error named.
"From −8 up to 0 is 8 degrees, then from 0 up to 13 is 13 more: 21 degrees. (Subtracting 8 from 13 gives 5, the classic error.)" A parent can mark a set in minutes and explain any wrong answer without being a maths teacher.
All 17 concepts in the book follow the pattern shown here.
