Frequently Asked Questions

Is this suitable for my child?

The The Number Detective (Ages 7-11) is absolutely perfect for children in Year 3, Year 4, Year 5 and Year 6 studying the national curriculum in England.

It is also very useful for children in Wales, Scotland and Northern Ireland.

It may also be suitable for children studying outside of the UK on similar curriculums such as the Cambridge Primary Curriculum or The Pearson Edexcel International Primary Curriculum.

How much is delivery?

Standard delivery within the UK is free of charge for all orders over £30. Orders below £30 carry a £3.95 delivery charge.
