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: Beginning to understand place value in 3-digit numbers.
In-depth Investigation: Sixteen Rocks
Children arrange place value cards to make 3-digit numbers and then add the digits. They look at patterns.
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 More 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.
