UNIT #1 -- Start the year right!! The isometric transformations lead so naturally into the development of congruence. The transformations and their properties help student express their understanding through proof and problem solving.



UNIT #2 -- The non-isometric transformation of dilation enlarges (pun intended) our understanding of similarity. Scale factors, proportionality, parallelism and many other dilation structures help students approach concepts such as similarity, geometric mean, special right triangles and trigonometry.


UNIT #3 -- This unit can be placed anywhere after Unit #2 but it follows nicely here because of the use of special right triangles, trigonometry and the pythagorean theorem in working with dimensions of 2D and 3D shapes.



UNIT #5 -- This is a personal preference... circle geometry could come in any location after Unit #2 but it is a great lead into Unit #5 Coordinate Geometry. The first objective of Coordinate geometry is deriving the equartion of a circle.This bridges the units and helps students leave the general plane to move onto the coordinate plane.



UNIT #4 -- I like this unit at the end of the year because it summarizes all of the years material as it looks at the relationships on the coordinate plane. It is also a nice transition to Algebra II next year. The coordinate work refreshes much of the key concepts from Algebra I.



UNIT #6 -- Not all states are placing the probability unit in the Geometry class as suggested by the Common Core State Standards committee but it can really work anywhere you want to put it.
