Research Principles

Number Sense Maths is informed by research into how high and low attaining children develop number sense, and how they solve and learn addition and subtraction facts. 7 key principles underpin the programmes.

Principle 1

Children benefit from moving beyond counting in ones to solve addition and subtraction facts. Not doing so is associated with low attainment.

Principle 2

Systematic teaching of derived fact strategies is effective for all, including children identified as low attainers.

Principle 3

Using a derived fact strategy approach is the best way to commit addition and subtraction facts to memory.

Principle 4

We have an innate ability to process quantities visually. We can use this to support our learning of addition and subtraction facts.

Principle 5

Developing an understanding of part whole relationships supports fluency in number facts.

Principle 6

Teaching derived fact strategies leads not only to fluency in number facts, but also to an understanding of number relationships.

Principle 7

The automatic retrieval of basic maths facts is critical to solving complex maths problems.
