Why is Mental Arithmetic so effective

Why is Mental Arithmetic so effective?


Mental Arithmetic was developed by teachers who recognised that effective practice requires more than repetition. Using principles that follow variation theory and intelligent practice, they designed a unique 'A, B, C' format that encourages children to think mathematically and make connections between different question types.

Part A - Questions where use of language is kept to a minimum.

Part B - Questions based on mathematical vocabulary and symbols.

Part C - Questions featuring one- and two-step word problems.

Four steps to using Mental Arithmetic

  1. 1. Initial assessment - Assess what level pupils are working at using the Entry Tests or National Curriculum Charts that are available as a free digital download.
  2. 2. Rigorous, daily maths practice - Schedule 10-20 minutes a day for pupils to work through part of a Mental Arithmetic book test. Many schools find that the easiest time to fit in sessions is either at the beginning of the day, as an early morning starter, or as homework.
  3. 3. Effective marking and feedback - Organise weekly group marking sessions to quickly and easily identify areas of difficulty and provide immediate feedback. Where further diagnostic assessment is required, use the Diagnostic Checks provided in the Teacher's Guides to assess the exact nature of a pupil's difficulties.
  4. 4. A positive maths culture - Encourage children to take pride in the development of their maths skills and monitor their own progress using the Progress Tests and Achievement Charts in each pupil book. Reward those whose achievements are especially significant with editable downloadable certificates.
