Venn Diagram Template with Guess My Rule Cards

I created this Venn Diagram template to use with Guess My Rule cards, but it could be used in so many different ways in the math classroom.

A couple of weeks ago, I was afraid that the lesson I had planned on Venn Diagrams wouldn’t take the entire 50 minute class period.  I was trying really hard to think up some sort of extension activity we could do that would extend my students’ understanding.

That’s when I remembered that I had decks of laminated shape cards in three different colors and three different sizes in my filing cabinet.

The shape cards are from the Guess My Rule activity described in Elizabeth Cohen’s Designing Groupwork.

I decided to take some of my 11 x 17 cardstock and print a Venn Diagram template on it.  

Then, I slid each sheet of cardstock into one of my 11 x 17 dry erase pockets.  

Here’s the finished product.  The left circle represents triangles.  The right circle represents green cards.

Even though I was worried about running out of time and needing an extension activity, the lesson I had planned did end up taking the entire class period.  

So,  I never ended up using this with my students.  Still, I thought I should still share in case it might inspire someone else.
