With a partner, measure your height. Record your height in your maths book.

Now measure your outstretched arms from finger tip to finger tip. Compare the width and height.

If the width is greater than, or less than the height, then you are a rectangle.

If the height and width are close to the same, then you are a square.

See if you can find a person in your class with the same measurements as you.

As a whole class order students height from shortest to tallest.

  • Who is the tallest?
  • Who is the shortest?
  • What do you notice about your class?
  • How many squares are there?
  • How many rectangles are there?
