Students discover the logic behind complementary, supplementary, and vertical angles, and are prompted to use each vocabulary word and apply each concept.
The standard track uses one lesson to introduce the vocabulary with manipulatives, and a second lesson to cement the application and meaning. Advanced track students master the main concepts in the first lesson in order to extend these concepts to the angles formed by a traversal. These concepts are later applied to formal equations during my equation unit.
These lessons are provided in three scaffolded versions: standard (s), hints (h), and (a) advanced to be differentiated within your classroom.
