I had a flex day built into my schedule, and I didn't want it to go to waste, so I focused on some topics my students had struggled with:
- Using the interior angles of a polygon to determine the measures of the exterior angles;
- Applying the interior and exterior angle theorems to overlapping shapes;
- Proving triangles congruent by SSS, SAS, ASA, SAA (or AAS), and HL;
- Properties of the midsegment of a trapezoid;
I start out class with a 15-minute "mini-lesson," giving my students some basic examples of what today's lesson will be about. Once the mini-lesson is over, I have them get to work within their groups on this worksheet.
I use this activity within cooperative groups, and I circulate to make sure they are getting the purpose of the questions.
The file includes spiral review problems.
This worksheet is intended to be written on directly.
Please download the pdf preview file first, so you can see exactly what's included; the product file is a word document, which you may personalize for your students.
Immediately before this worksheet, I use the assessment named 'Geometry Individual Test Proofs and Concurrency Fall 2013' (http://www.teacherspayteachers.com/Product/Geometry-Individual-Test-Proofs-and-Concurrency-Fall-2013-1270008
), and immediately after this worksheet, I use the worksheet named 'Interior and Exterior Angles/Parallel and Perpendicular Lines Fall 2013' (http://www.teacherspayteachers.com/Product/Interior-and-Exterior-AnglesParallel-and-Perpendicular-Lines-Fall-2013-1070651
