In this unit the learner will practise converting between centimetres and millimetres before moving on to metres and kilometres. They will then focus on finding the perimeter of rectilinear shapes, initially counting grid squares, and then calculating perimeter from the given lengths of different sides. The learner will further develop their understanding of perimeter by creating their own rectilinear shapes.
Year 4 Length and Perimeter consists of:
- Parent/tutors guide
- Length and Perimeter 1 – I can convert between different units of measure.
- Length and Perimeter 2 – I can measure and calculate the perimeter of a rectilinear shape.
- Length and Perimeter 3 – I can measure and calculate the perimeter of a square and rectangle.
