Description
- The pink tower has ten pink cubes of different sizes, from 1 centimeter up to 10 cm in increments of 1 cm.
- The work is designed to provide the child with a concept of "big" and "small."
- The child starts with the largest cube and puts the second-largest cube on top of it.
- This continues until all ten cubes are stacked on top of each other.
- The control of error is visual. The child sees the cubes are in the wrong order and knows that they should fix them.
- The successive dimensions of each cube are such that if the cubes are stacked flush with a corner, the smallest cube may be fit squarely on the ledge of each level.
- Ten solid wooden cubes varying in size from 1 cubic centimeter to 1 cubic decimeter.
- These are pale pink or plain wood. A strong pink must not be used.
- If it is used, children are more aware of color than of size. If in plain, lightly varnished wood, a very good hard wood must be used.
