The principles of success in maths

Helping pupils to understand the logical principles underlying maths may improve their mathematical achievement, according to the findings of a randomised controlled trial published by the Education Endowment Foundation (EEF).

Mathematical Reasoning lessons focus on developing pupils’ understanding of the logic principles underlying maths, and cover principles such as place value and the inverse relation between addition and subtraction. One hundred and sixty English primary schools took part in the trial, and were randomly allocated to receive either Mathematical Reasoning or to be in the control group. The control group was given the opportunity to take part in the programme the following year. Teachers in the intervention schools delivered the programme to Year 2 pupils over 12 to 15 weeks as part of their usual maths lessons. Learning was supported by online games, which could be used by pupils at school and at home.

The independent evaluation by a team from the National Institute of Economic and Social Research (NIESR) found a small but statistically significant effect size of +0.08 on maths achievement for pupils who took part in the programme, compared to other pupils. It had the same impact for pupils eligible for free school meals. They also found some evidence that the programme had a positive impact on mathematical reasoning.
