##### Description

In Module 5, students consider part–whole relationships through a geometric lens. The module opens with students identifying the defining parts, or attributes, of two- and three-dimensional shapes, building on their kindergarten experiences of sorting, analyzing, comparing, and creating various two- and three-dimensional shapes and objects. Students combine shapes to create a new whole: a composite shape. They also relate geometric figures to equal parts and name the parts as halves and fourths. The module closes with students applying their understanding of halves to tell time to the hour and half hour.

The Following Topics Are Included within this Module:

• Topic A:  Attributes of Shapes
• Topic B:  Part-Whole Relationships Within Composite Shapes
• Topic C:  Halves and Quarters of Rectangles and Circles
• Topic D:  Application of Halves to Tell Time

Lessons are organized under each of the topic areas.
