Year 1 Place Value: Problem-Solving Investigations

These in-depth Year 1 Place Value problem-solving investigations will develop maths meta-skills, and enable children to learn to think mathematically and articulate mathematical ideas.

• Partition teen numbers; compare numbers to 20
• Count to 100 in 1s and 10s
• Compare/order numbers < 100
• Count to 100 in 1s and 10s; say 1 or 10 more/less
• Place value in 2-digit numbers
• Compare and order 2-digit numbers using place value
• Order 2-digit numbers using place value; say 10 more/less.

In-depth Investigation: Fill in the Box
Children fill a matchbox with items and count them accurately.

In-depth Investigation: Tricky Tracks
Children use reasoning and logic to play ahead in playing a game on a 1-20 track.

In-depth Investigation: Domino Digits
Children find which numbers on a 1 - 100 grid they can make using dominoes - each domino can only be used once.

In-depth Investigation: Pairs in Purses
Children use reasoning and logic to work out pairs of 2-digit amounts that can be made in the two purses given only ten coins.

In-depth Investigation: Calculator Capers
Children create teens numbers using place value additions.

In-depth Investigation: New Neighbours
Children use digit cards to make 2-digit numbers between neighbouring multiples of 10.

These problem-solving investigations are part of our Year 1 Place Value block. Each Hamilton maths block contains a complete set of planning and resources to teach a terms worth of objectives for one of the National Curriculum for England’s maths areas.
