Weekly Primary Task – Oct 23, 2016

Allow students time to explore the attributes of various 3-D shapes. Have them identify the faces, edges and vertices of the 3-D shapes? Present various problems for them to solve:

  1. If you had 3 cones, 2 cylinders and a sphere, how many faces would you have? How do you know?
  2. You have 1 cube and your friend has 4 cylinders. Who has more faces? How do you know?
  3. I have some objects and in total I counted 8 faces. What might the objects be? Explain your thinking.
  4. I have a collection of objects that have 7 faces and a point. What shapes could they be? Explain your thinking.

Have the students create their own clues to create a problem.
