NEW 2.0 version contains 3 lessons assembled into modules. Guzinta Math: Introduction to Proportions focuses on methods for identifying proportional relationships, using equations, division, cross multiplication, and identifying a proportional relationship as being described by a straight line through the origin of a coordinate plane. This lesson app also includes an introduction to the constant of proportionality. For one-on-one or whole-class mathematics instruction, use this Guzinta Math lesson as a supplement for introducing proportions and introducing complementary and supplementary angles--all key concepts in 7th grade. The app includes detailed instructor notes for each guided practice problem, with notes about extending discussion around each worked example and problem. The secondary focus of this lesson is on angle relationships, such as complementary and supplementary angles, and using these relationships to solve for unknown angles.
