U1L1 Build It!

This lesson establishes the straightedge and compass moves that students will use to perform various constructions. Students build on their previous understanding of circles as a set of points all equidistant from the center and line segments as a set of points on a line with two endpoints. Constructions are used in subsequent lessons to introduce students to reasoning about distances, generating conjectures, and attending to the level of precision required to define rigid motions later in the unit. This activity includes lesson summary videos and practice problems
