Sorting is a popular activity for all children in the classroom. Montessori spoke of children having access to small objects to sort. This activity not only strengthens fine motor skills but also problem solving by organizing, discriminating, comparing and contrasting.
If you have small objects that vary in color or size, make your own sorting work for your child. We do this work on a rug on the floor. Also important is having the child put the work away by themselves including rolling up the rug. This helps the child develop a sense of order.
