1. Year 5 Block 5-Perimeter and Area
WR Small Step-Measure Perimeter
NCLO: Measure and calculate the perimeter of composite rectilinear shapes in cm and m. Calculate and compare the area of rectangles (including squares), and including using standard units, cm2,m2 estimate the area of irregular shapes.

2. Mathematical Talk Which measures are missing from the diagram?
Explain to your partner why you think the line is ____cm long.
Can you prove it?
Can you make a rectilinear shape where your partner can work out the perimeter if you miss off the length of one of the sides?
If you know the length of one side and part of the opposite side is known.
