In this lesson, we will learn how to use our rulers accurately and begin measuring in cm and mm

In this lesson, we will use our rulers accurately and draw and measure lines in cm and mm

In this lesson, we will make appropriate estimates of length by using our cm estimators or Dienes. We will also be comparing our estimates and the actual lengths

In this lesson, we will apply all that we have learnt in this unit so far and practise answering different styles of questions on length and measure

In this lesson, we will investigate different 2D shapes and calculate their perimeters in cm and mm, including regular shapes without all measurements provided, and irregular shapes.

In this lesson, we will investigate different 2D shapes and calculate their perimeters in mixed units such as cm and mm

In this lesson, we will measure different 2D shapes and compare their perimeters in mixed units. We will compare lengths that are measured in different units to determine which is longer using greater than and less than symbols.

In this lesson, we will look at regular and irregular 2D shapes and calculate their perimeters in mixed units

In this lesson, we will apply problem solving strategies in the context of worded questions involving measuring length. We will walk through potential approaches together.

In this lesson, we will apply all that we have learnt in this unit and practise answering different styles of questions around length and measurements.
