What students practise
I can find area by counting unit squares or multiplying, and perimeter by adding side lengths.
Students understand area as the number of unit squares that cover a shape with no gaps or overlaps and perimeter as the distance around it, then find both for rectangles and rectilinear figures.
Key words
- area
- the number of unit squares that cover a shape
- perimeter
- the distance around a shape
- unit square
- a square with sides one unit long
- square unit
- the unit that measures area
- side length
- how long one side of a shape is
Common mistakes
- Finds the area when asked for the perimeter, or the perimeter when asked for the area.
- Writes units for an area, or square units for a perimeter.
- Adds only the labelled sides of an L-shaped figure.
