Ten pink wooden cubes that range progressively from 1 cubic centimeter to 10 cubic centimeters.
- Invite the child to the lesson. Ask the child to watch.
- Starting with the cube on top, carefully carry the cube with a pincer grip and place your sub dominant hand underneath the cube itself.
- Place the cube in a random spot on the rug.
- Continue this process one cube at a time while inviting the child to help by doing the same.
- Once all the cubes are placed randomly on the rug, look for the largest cube and pick it up by the top with all five fingers on your dominant hand and place it in the middle of the rug.
- Continue this process by progressively picking up the next largest cube and placing it mid-center of the cube beneath it.
- Once the tower is complete, invite the child to walk around the tower with you and to look at the tower from a bird’s eye view directly down at it.
- Piece by piece, carefully take the pink tower apart and randomize it.
- Invite the child to now build the pink tower.
Exercise 1, the child performs the presentation.
Exercise 2, do the same thing as exercise 1 except progressively place the cubes to one corner instead of mid-center; walk around and admire the tower and then sit back down and carefully take the smallest pink cube off the top and “walk the path” of the tower by carefully sliding the smallest cube on the edges of the cubes. Disassemble, and let the child perform the exercise.
Large, small, larger, smaller, largest, smallest.
Grading at a Distance: Place two rugs on the floor far apart from one another. Place all the cubes on one rug, and request the child to build the tower on the other distant rug by asking him to bring the largest cube, and then the next largest cube, and so on.
Larger or Smaller: Sit away from the rug and hold a random cube, request the child to bring a larger or smaller cube from the rug.
Control of Error
Lies within child, cubes wont stack properly and therefore won’t stay stacked.
Visual discrimination of dimension.
Refinement of voluntary movement, preparation for the mathematical mind, muscular education of the grip.
3 – 3 ½
In the future, the child can use this in combination with the brown stair and make wonderful towers and designs.
