Introducing proofs in Geometry can be difficult. This product contains simple geometric proofs that you can use with your students while they begin to explore the process of writing their own two-column proofs. There is a quick review of the contents that students will need to know before beginning

Once your students have learned Side-Side-Side Postulate and Side-Angle-Side Postulate, they are ready to really begin building their own proofs for congruent triangles. Get them to take ownership of the process with this 2-day common core collaborative activity. This is a perfect activity to help

Let's face it: Geometric Proofs are very difficult for students, and they're very difficult for teachers to teach, because there is so much information required to get across (such as knowing that the idea that 3 = 3 is the "reflexive property of equality.")
To get my Geometry students started, I t

Are you having trouble getting your students to take effective notes during math lessons? Are you looking for quick activities that can be completed in a math journal or at the end of a lesson as a check for understanding? If so, these activities are for you.

Introduce proofs in your classroom using hands-on activities that will help your students understand the basic idea and format of proofs. This lesson comes with a powerpoint to assist you and the students with the lesson. The other pieces of the lesson are seen below: Lesson Plan - Step-by-step guid

In this activity, students will practice completing two column proofs in 3 sections. The first section give students the statements. Students will drag and drop the reasons in to the table. In the next section, students are given the statements but now have to type the answers in to the reasons sect

Geometric proofs have a long history in mathematics
stretching back to Euclid over 2000 years ago. This paper
uses 13 different proofs to stimulate students mathematical

This activity is to help students organize two column proofs in Geometry. There are 8 two column proof mats where the students can organize the pieces on. Following the mats are the pieces. There are written in correct format and in order as the key. Each mat and pieces have a number in the upper

Do you have a hard time getting students to understand geometric proofs?
This notes page with a graphic organizer helps students recognize what can and cannot be used in proofs.

The attached worksheet contains 4 guides notes proofs on SSS and SAS. As I went through this lesson, students made mini-index card definitions such as...SSS PostulateSAS PostulateMidpointPerpendicular Reflexive Property In order for students to understand proofs, past research shows that it helps th

The attached document contained very scaffolded notes for an introduction to CPCTC proofs. (The worksheet should be cut in half, paper saver handout) Blanks are provided for filling in definitions and postulates. The clouds are intended for students to choose whether they want to use SSS, SAS, AAS,

I give my geometry students this sheet with 7 steps that help them write geometric proofs. It includes advice for approaching a geometric proof.

This is a great activity for students to practice matching reasons for given statements in basic geometry proofs.
If you want to use it as a matching activity, print out each individual proof (pages 3-6) and cut out the diagram, statement-reasons, and each individual reason separately. I did each o

The following worksheet should be cut in half (The top two proofs are the same as the bottom two). Great for saving paper! These are two great proofs for introducing the definition of alternate interior angles. Students must be aware of the reflexive property and vertical angles property and midpoin
