The books in the Open-ended Maths Investigations series provide teachers with open-ended investigations matched to the following strands of mathematics: number; money; measurement; space; chance and data; patterns and algebra. The investigations encourage pupils to apply higher order mathematical strategies creatively and effectively as they develop proficiency in a wide range of problem-solving strategies. Open-end Maths Investigations can be used in isolation, in sequence or dipped into as teachers require, providing a great supplement to every maths scheme of work.
