Geometry Instructional Unit


Alison Hays


This unit is an introduction to geometry.  I plan to use it with a Technical Mathematics II class.  I expect some of the lessons, especially lessons 1 and 3, to take more than one day.  This unit will definitely last 10 days.

Lesson 1:  Introduction to Geometry and GSP

Lesson 2:  Angles

Lesson 3:  Parallel Lines 

Lesson 4:  Triangles

Lesson 5:  Polygons and Parallelograms

Lesson 6:  Rhombuses

Lesson 7:  Rectangles and Squares

Lesson 8:  Trapezoids


This unit is adapted from Chapter 4 of the book Algebra One Interactions published by Holt, Rinehart, and Winston.
