Warm-up Which One Doesn’t Belong: Five-sided Shapes

Which one doesn’t belong?

  1. Five-sided shape.
  2. 5 lines, almost a pentagon.
  3. Student drawing of pentagon.
  4. Five-sided shape.

Activity 1 Draw Shapes

  1. Complete the shape to make a quadrilateral. Then draw a different four-sided shape.

    3 connected lines on dot paper.

  2. Complete the shape to make a pentagon. Then draw a different five-sided shape.

    Three connected lines.

  3. Complete the shape to make a hexagon. Then draw a different six-sided shape.

    Three connected lines.

  4. Compare your shapes with your partner’s shapes. Find one way your shapes are the same and one way they are different.

Activity 2 What Shape Could It Be?

  1. Clare drew a shape that has fewer than 5 sides. Circle shapes that could be Clare’s shape.

    5 shapes with varying numbers of sides.

  2. Draw a different shape that could be Clare’s shape.

    Dot grid.

  3. Andre drew a shape that has 4 corners. Circle shapes that could be Andre’s shape.

    6 shapes on a dot grid. 5 closed, 1 open.

  4. Draw a different shape that could be Andre’s shape.

  5. Han drew a shape that has more corners than Andre’s shape. Draw two shapes that could be Han’s shape.

    Dot grid.
