How Many Halves?

Draw one straight line to divide each shape into halves that are the same size and shape.

  • 1 A triangle with a dotted line down the middle.

  • 2 A shape with 5 sides and 5 corners that looks like the letter M. It has a flat base and 2 points at the top that look like the tops of triangles.

  • 3 A pentagon.

  • 4 A shape with 6 sides and 6 corners that looks like 2 sideways triangles joined together where their points should be.

  • 5 A trapezoid.

  • 6 A rhombus.

  • 7 A triangle.

  • 8 A hexagon.

  • 9 An octagon.

Ongoing Review

  • 10 Which does not show a way to make 15?

    • A 5 + 10

    • B 6 + 9

    • C 6 + 6 + 3

    • D 6 + 6 + 4

NOTE

Students draw lines to determine the number of ways they can divide each of the 2-D shapes into equal halves.
