Everyday Math-Unit 6 Overview

In previous grades, Everyday Mathematics proceeded from children’s experiences with the everyday world to idealized 3-dimensional shapes. Children were asked to identify 2-dimensional shapes, edges, and vertices within these shapes. Thus, the progression in previous grades was from 3-dimensional to 2-dimensional. Beginning with this unit, the order is reversed. Children start with points and then move on to line se
gments, rays and lines. Then they explore the relations among segments, rays, and lines as well as the geometric figures that can be built from them, including angles, polygons and frames for prisms and pyramids. Unit 6 has three main areas of focus:

*To investigate ling segments, rays and lines

*To explore polygons, including triangles, and quadrangles

*To draw and measure angles
