Maths Unit: Place Value to 120
In this unit, students learn about the place value of 3-digit numbers (up to 120), deepening their understanding that the value of a digit depends on its place. The unit begins with a revision of the part-part-whole concept before moving on to how 3-digit numbers (up to 120) can be created and partitioned. Students explore the link between a number’s name, digits and its composition. There is a strong focus on using proportional equipment to represent and model numbers.

Learning goals
- We are learning to show that one- and two-digit numbers can be partitioned in different ways, such as partitioning two-digit numbers into tens and ones.
- We are learning to count collections to 100 using place value groupings.
