Essential Mental Arithmetic

Close the Key Stage 3 maths gap with targeted maths intervention books based on the best-selling Mental Arithmetic series.

Essential Mental Arithmetic

Many students arrive at secondary school without secure foundational maths skills from Key Stage 2. Essential Mental Arithmetic helps you identify gaps in understanding and deliver targeted, individualised intervention that gets students up to speed quickly.

This new edition of the bestselling Mental Arithmetic series comprises six graded workbooks, each featuring over 900 differentiated questions covering essential mental maths skills from the primary curriculum.

Personalised student learning

Organised by ability rather than age, Essential Mental Arithmetic helps you identify gaps in understanding and deliver targeted, individualised intervention for each student.

1. Assess: Use the free Entry Tests to identify where each student should start. The first three books are suitable for students working at a lower Key Stage 2 level, while books 4-6 are designed for students working at an upper Key Stage 2 level.

2. Practice: Schedule 10–20 minutes of daily practice, either as part of maths lessons or as homework. 

3. Track progress: Regular testing allows you to monitor improvement and quickly identify areas that need additional support.

Maths recovery through intelligent practice

The pedagogy behind Essential Mental Arithmetic was developed by experts who recognised that effective maths fluency requires more than repetition. Using principles rooted in variation theory and intelligent practice, the series features a unique ‘A, B, C’ format that encourages students to think mathematically and make connections between different question types.

This approach delivers fast, focused intervention on core Key Stage 2 skills. The carefully graded tests ensure that every student is appropriately challenged, building the skills and confidence needed for the Key Stage 3 curriculum.

These books are easy to understand, give you a good scope to work with your child, encourage work at the level of the child/student. Guided answer book for easy marking and now I have discovered the Teacher's Guides I am sure it will help me teach more effectively and give the lessons a greater element of fun, whilst teaching at the level required. Most importantly they are affordable and can be bought one at a time or as series, it gives room for plenty of practice and growth of confidence to both me as a parent and my child, and we both learn and have lots of fun. My oldest is 12 and I used it with him, I am a single mother of 6 down to the age of 4 and look forward to many more years of growth for my children with Schofield and Sims. Thank you.
