Classify shapes based on defining attributes using examples, variants, and non-examples.
EngageNY 60 min(s)
In this lesson, students use straws cut at various lengths to create and classify shapes. They develop a list of the common attributes for a set of shapes, and as they create a new shape with their straws, they decide if it has all the listed attributes. (In this lesson, students do not use the names of shapes, but describe them in terms of their attributes. For example, rather than describing a shape as a triangle, students describe it as having three sides and three corners.)
