Geometry

          The youngest group of students participated in a TERC Investigations geometry unit. They observed, described, compared, classified and built 2-D and 3-D shapes. During class, in pairs, the students sorted and classified 18 2-D shapes into groups. Each student designed their own quilt square using squares and triangles that they repeated to create a pattern. They were able to see how repeating the pattern created different shapes. They developed their vocabulary to describe 3-D shapes by matching geoblocks to outlines of the block faces. In pairs, they built their own 3-D rectangular prisms.
