Year 3 Place Value - Problem-Solving Investigations

These in-depth maths investigations are open-ended problem solving activities for Year 3 children.

In-depth Investigation 1: Three Coins
Using exactly three coins, children work out how many amounts can be made between £1 and £2.

In-depth Investigation 2: Money Bags
Children use their knowledge of counting in 10s to solve a problem involving money.

In-depth Investigation: Counter Place Value
Children place counters on a place value grid to make 3-digit numbers and then use logic to ensure they have made all the combinations.

In-depth Investigation: Lost Logic
Children use their knowledge of inverse operations to solve a logic problem.

In-depth Investigation: Guess my Number
Children use their knowledge of 3-digit numbers, rounding, and properties of numbers to work out a mystery number.

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

These problem-solving investigations come from our Year 3 Maths Blocks. 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.
