Sorting and classifying are fundamental parts of life and are used on a daily basis. Forming "classes" is an essential element of mathematical reasoning, as it is the basis for all conceptual development.

Sorting activities should always begin with real objects before moving on to toys and typical educational materials.

Sorting activities should begin with two very different objects before moving on to similar objects, and three or more objects.
