Halloween Pop-Up Spiders and 3D Shapes

22 Oct

Our next idea for a mathematical Halloween activity involves 3D shapes. Using a pop-up dodecahedron pupils can review the properties of 3D shapes such as vertices, faces and edges and have a great pop-up spider to take home.

Where’s the maths

  • Nets of 3D shapes
  • Properties of shapes; faces, edges and vertices
  • Planes of symmetry
  • Angle properties of each face of the dodecahedron

You will need

  • Template of a dodecahedron, download one from Sen teacher website from here.
  • Some black card
  • Elastic bands
  • Black pipe cleaners for the legs
  • Elastic bands for pop-up ability
  • Stick on eyes

How

Download a template of a dodecahedron from here the SEN website and use as a template.

Cut out the dodecahedron on black card but separate into two pieces like this;

Now test the pop-up ability of your spider by following this quick video;

Then decorate your spiders with eyes and legs made from pipe cleaners! Alternatively make a normal 3D Dodecahedron to make a spider that does not pop-up!

We like to hear how the ideas worked for you and would love to see a picture of any spiders made by your class!

      Fantastic! I got some black glitter spray from the works to give the spiders sparkle! Forgot to take photos before pupils took home!
