Introduction to Area

Lesson

Unit squares are special squares that help us work out the area of shapes. We call them unit squares because they have sides measuring $1$1 unit, but we don't need to know the unit of measurement.

If we have a two-dimensional shape (2D), we can work out how much space it takes up (the area), by seeing how many unit squares fit inside the shape. In the video, you'll see how we do this, as well as how we can add up parts of unit squares.

Find the area of the shape.

Remember!

We don't need to know the unit of measurement when we use unit squares. We can also add up parts of unit squares, if they are not complete squares.

Create and use appropriate units and devices to measure length, area, volume and capacity, weight (mass), turn (angle), temperature, and time.
