Book 1 builds the number work that everything else rests on. It starts with the four operations and finishes with reverse percentages and profit and loss, the topics that catch out the strongest candidates.
Inside this book, modules 1 to 11
- Basic operations, including long multiplication and division
- Place value and decimals
- Four operations with decimals
- Number properties, primes, squares and cubes
- Prime factorisation, HCF and LCM
- Fractions and percentages, through to reverse percentages
- Percentage profit, loss and successive change traps
Every module follows the same structure: clear teaching, fully worked examples, practice questions, a mini test, and complete answers. Nothing is left for a parent to work out.
