Common Core Geometry - Unit #7 Dilations and Similarity
Description
This 12-lesson unit contains lessons on dilations and similarity. Dilations are performed both in the Euclidean and coordinate planes. Similarity is defined in terms of transformations using dilations. Properties of similar figures and specifically similar triangles are proven and then used to establish facts about partitioning, the medians of triangles, and right triangles. Finally, similarity is used to prove the Pythagorean Theorem.

TRAPS & PITFALLS
No real traps or pitfalls here - not if you have introduced the previous concepts correctly.
PAST CONNECTIONS
Students will use the concepts covered in G.CO.4 and G.CO.5. The definitions and the composite transformations will link isometry to congruence.
FUTURE CONNECTIONS
This is the developing of the connection to congruence. The next few objectives will rely heavily on this definition of congruence.
MY REFLECTIONS (over line l )
This seems to come quite easily. I think this is one of the reasons why we introduce congruence this way. It makes sense that if one is identical to the other (or can be mapped onto the other) that they would have to be congruent. In many ways this was a quick objective because it was an easy stepping stone to bigger ideas.

About This Course
Welcome to the Math Medic Geometry course! Here you will find a ready-to-be-taught lesson for every day of the school year, along with expert tips and questioning techniques to help the lesson be successful. Each lesson is designed to be taught in an Experience First, Formalize Later (EFFL) approach, in which students work in small groups on an engaging activity before the teacher formalizes the learning.
Our Geometry course develops reasoning, justification, and proof skills through an in-depth study of shapes and their properties, rigid transformations and congruence, and the relationship between similarity and right triangle trigonometry. Rich opportunities for problem solving culminate in the unit on surface area and volume. This course was created using the Common Core State Standards as a guide. The standards taught in each Math Medic Geometry lesson can be found here . Additionally, we've chosen to include a unit on Statistics and Probability that can be used as a stand-alone unit at any time during high school course work. The unit overviews and learning targets for the Math Medic Geometry course can be found here .
