Go Deeper with Hamilton's Problem-solving Investigations

Ruth Merttens By Ruth Merttens

Hamilton’s In-Depth Problem-Solving Investigations provide school-wide solutions to the challenges of building investigative skills from Early Years to Year 6.

The skills of mathematical problem solving and investigation are fundamental to the maths curriculum for England and for developing sophisticated and modern mathematicians everywhere. However, these skills do not fall naturally out of the teaching of the maths curriculum itself. They require dedicated time, content and pedagogy. Most challengingly, they require teachers to present children with graded activities and problems that are relevant to the curriculum while at the same time develop skills in mathematical reasoning and logical thinking, and give children sufficient practice to feel confident in these.

Hamilton's Problem-Solving Investigations provide materials and advice for teaching these skills well, in a variety of ways and contexts, and with confidence.
