Name:Date:

Number the cards 1, 2, 3 … to put them in the right order.

  1. Order the shapes by how much surface they cover, smallest first.
    • triangle: base 12 cm, height 7 cm
    • triangle: base 14 cm, height 2 cm
    • parallelogram: base 7 cm, height 3 cm
    • parallelogram: base 6 cm, height 5 cm
  2. Put the shapes in order of area, smallest first.
    • parallelogram: base 6 cm, height 5 cm
    • triangle: base 8 cm, height 2 cm
    • parallelogram: base 7 cm, height 3 cm
    • triangle: base 14 cm, height 2 cm
  3. Find each area in cm², then put the shapes in order, smallest first.
    • triangle: base 6 cm, height 4 cm
    • parallelogram: base 4 cm, height 4 cm
    • triangle: base 10 cm, height 5 cm
    • triangle: base 14 cm, height 2 cm
  4. Use ½ × base × height for triangles and base × height for parallelograms. Order by area, smallest first.
    • triangle: base 12 cm, height 7 cm
    • parallelogram: base 4 cm, height 4 cm
    • parallelogram: base 6 cm, height 5 cm
    • triangle: base 6 cm, height 4 cm
  5. Work out each area, then order the shapes from smallest to largest.
    • triangle: base 10 cm, height 5 cm
    • parallelogram: base 9 cm, height 4 cm
    • triangle: base 6 cm, height 4 cm
    • parallelogram: base 5 cm, height 3 cm
  6. Put these shapes in order of area in cm², smallest first.
    • triangle: base 8 cm, height 2 cm
    • parallelogram: base 9 cm, height 4 cm
    • parallelogram: base 5 cm, height 3 cm
    • triangle: base 10 cm, height 5 cm
