Add numbers with up to 3 decimal places - Problem-Solving Investigation - Year 6

This in-depth maths investigation is an open-ended problem solving activity for Year 6 children. It can be used to support teaching towards objective: Add numbers with up to three decimal places.

In-depth Investigation: Decimal Pyramids
Children add numbers with 3 decimal places to give a number with 2 decimal places. They add numbers with 2 decimal places to give a number with 1 decimal place. They then add numbers with 1 decimal place to give a whole number.

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 6 Decimals and Fractions 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.
