The unit begins with solids. Students examine solids and sort them on the basis of criteria of their own choosing. Discussion of these criteria leads to the concept of properties. Then, lessons focus on individual properties of a set of solid objects.

The two use kit comes with all of the great materials you’d expect from the STC Program along with a box containing the materials for a second, non-concurrent use. All you need to do is set the box aside until you are ready for it.
