In the old days, I would start off my year of Geometry by explaining to my students the need for three undefined terms (or undefined notions), so that we wouldn't end up with circular reasoning, and then I went about showing them examples of how to name points, lines, and planes, and so forth.
The lecture inevitably was too long and students lost interest.
Now, I open the first day with a mini-lesson of 15-20 minutes, and then I have them work cooperatively together to complete this worksheet. I have them appoint a "reader" within each group to read the prompts, as there is a lot of textual information, but I find the students are engaged to a much greater extent during the block than they used to be with my lectures.
I circulate to make sure they are getting the point of the questions.
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, (as this is the first worksheet of the semester), I use the assessment named 'Geometry Final Exam Spring 2014' (http://www.teacherspayteachers.com/Product/Geometry-Final-Exam-Spring-2014-multiple-choice-2-versions-with-key-713199
), and immediately after this worksheet, I use the worksheet named 'Postulates Axioms and Congruence Fall 2013' (http://www.teacherspayteachers.com/Product/Postulates-Axioms-and-Congruence-Fall-2013-1047702
