Sorting by Attribute

It is never to early to introduce math and science concepts.  Sorting by attribute is one of the first skills young children can learn which bridges both math and science.
When we talked about lights in the sky, we had an activity to sort stars by size.  All the stars were basic wood, so the only attribute that differentiated them was size.

Another time we had some little frogs that were different colors.  They were all the same size so the only way to differentiate them was color.

There are many ways to practice sorting at home.  Sorting silverware, socks or other household items is an easy way to practice the concept.  We sometimes take our big bin of animals and sort them by very non-standard attributes such as animals with fur vs. animals with scales, or animals with spots vs. animals with stripes, or animals that have sharp teeth vs. animals that don't have sharp teeth.  Try it at home.
