This bundle contains a video and Promethean Board flipchart which clearly explain how to solve mult-step equations; they contain step-by-step instructions as well as student examples. The worksheet requires students to write and solve multi-step equations to determine the measures of angles of different polygons. The STEM project requires students to design and build one of these polygons. All three may be used together or separately or in any combination. The STEM project can be differentiated
