A fun idea to support the development of addition skills, adapted from a homemade resource shared on PINTEREST:  The Imagination Tree

Materials: 

  • Selection of small balls or pompoms
  • Medium size cardboard box
  • Two cardboard tubes
  • Some card to make thin rings numbered 1 -10 (in large print or braille) to hook over the tubes
  • Stars or foam shapes (or other decorative items) to decorate the box
  • Duct tape to trim the edges of the box (optional)
  • Textured paper to cover the tubes
 

Procedure: 

  • Stand the box on its long end.
  • Cut two holes in the long side of the box to fit the width of the cardboard tube.

  • Cover each tube with a different textured paper, or add a foam shape to distinguish them apart.
  • Cut a triangle from one end of each tube.  (See below.)

  • Push the tubes through the two holes and position them ready to receive the pompoms.
  • Play with the addition machine:
    • Children can have fun sending the pompoms or balls down the tubes. 
    • Add the number rings over each tube and post the corresponding number of pompoms or balls down each one. Count the total number of pompoms or balls as they come out the other end of the tubes! 
 

Variations: 

  • Use balls with sound
  • Use balls with texture
