Add by partitioning or counting on - Problem-Solving Investigation - Year 2

This in-depth maths investigation is an open-ended problem solving activity for Year 2 children. It can be used to support teaching towards the objectives: Add by partitioning or counting on.

In-depth Investigation: Diagonal hundreds
Children use trial and improvement to place numbers in a grid to give a pair of diagonals whose sum is equal to 100.

This investigation will develop maths meta-skills, support open-ended questioning and logical reasoning, and enable children to learn to think mathematically and articulate mathematical ideas.

This problem-solving investigation is part of our Year 2 Calculation block. Each Hamilton maths block contains a complete set of planning and resources to teach a term’s worth of objectives for one of the National Curriculum for England’s maths areas.
