I love this Montessori activity. When I taught at a Montessori school in Naples, Italy we used this activity every morning in the 4 year old preschool class. The kids knew when they arrived that they would go pick out a push pin and a square of carpet or foam along with the daily shape. This is great for those fine motor skills and to help with concentration.
After a child uses a push pin to punch holes in the outline of a shape such as shapes of continents, letters, numbers, circles and so on...then he/she removes the surrounding paper to reveal the completed shape! The completed shape can be used for a craft or building a map as seen below!
