Check-In: Questions 2–3

  1. Write your riddle. Keep the shape in mind as you write clues that will help someone guess the shape. Your first clue can have several 3-D shapes as answers. With each additional clue, the reader should be able to narrow down the choices until there is only one correct answer. Use the following questions to help you think of clues.
    • How many edges, faces, and vertices does the shape have?
    • What shapes are the faces?
    • Are the faces parallel?
    • Are the faces congruent?
    • Does the shape have right angles?
  2. After writing your riddle, read it to your partner to see if there are sufficient clues to guess the answer.

Professor Peabody looked at the cone and the square prism and said, “These shapes are both prisms.” Write why you agree or disagree with his statement.
