Geometry Proofs Using Jamboard

For my Jamboard activity I constructed an activity for students to work collaboratively to do proofs in geometry. This would probably be for a middle school or high school geometry class. I would categorize this as a graphic organizer activity.

I created two proof tables in Google Draw that had all of the statements without any of the reasons. I would then divide up the students into groups and assign each group a slide. I would make more slides if I were actually using this in a classroom so that there would be 3-4 students per group. Using groups for this activity is helpful because if some students didn’t have the technology to access Jamboard, they would still be working on the problem with their group mates. Also working in groups means that there may be less than 20 students on the one Jamboard at the same time. They would work together to fill out the reasons column of the proof table using the text boxes or the post-it notes. If the students were online I would put them in breakout rooms with their group so they could talk. Once they were done, we would go over them in class.

The goal of this activity would be to help students identify what to use as their reasons when doing proofs. The proof is already started so they are focusing on just identifying the reasons for each statement, whether they are theorems, given, definitions, etc.

Here is an example of what it may look like once the students have done the activity

  1. Great idea for a lesson – it does a fine job of showcasing Jamboard. An excellent way for students to share their learning.

    First rate post – well designed. Good layout and especially like the demo answer.

    PS. You need to reset the sharing setting on your Jamboard

  2. This is really impressive! It’s easy to create simple activities on Jamboard for younger learners, but you were able to make a much more elaborate lesson that’s age-appropriate for high schoolers!
