The Pink Tower is a traditional piece of Montessori “visual” work within the Sensorial “curriculum”. The work involves 10 pink wooden cubes ranging from 1 cm cubed to 10 cm cubed, differing in 3 dimensions. The Pink Tower introduces children as young as 3 years old to base ten. The cubes increase progressively in the algebraic series of the third power. Therefore, the second cube equals 8 of the first; the third cube equals 27 of the first, etc. This sensorial work isolates the quality of size. It is worth purchasing a high quality Pink Tower from a Montessori vendor like Bruins but there are less expensive versions like the Kid Advance Montessori Pink Tower. Below is a description of a Pink Tower lesson as I was taught in my certification program. If you need more visually, check out You Tube for lessons. Here is one Pink Tower presentation.
Sit on child’s dominant side, pick up the largest cube with fingertips of each hand on either side of the cube and begin to construct the tower. Pause & take time to center using a bird’s eye view as your measure.
From time to time, stop and pause to compare a cube to the next smallest one to make certain you chose the appropriate next cube.
When the tower is complete, check centering using a bird’s eye view: “Largest. Smallest.” Randomize cubes again. Offer the child a turn.
Using cards to supplement the work is always a good idea and worth the effort and money. You can purchase the cards already cut and laminated or you can prepare the cards yourself by purchasing through Montessori Print Shop.
Proceed as above but align the cubes at one corner and along two edges rather than centering them. Show the child that the smallest cube will fit in and slide around the space left on the unaligned sides of each cube.
