Create Interactive Number Set Venn Diagrams with Google Slides

I'm in number sets and set theory land in our Applied Math curriculum, which means I'm in the midst of my yearly debate on what, exactly, matters about classifying numbers, and what doesn't.

That's manifesting itself this year in a desire to bring more interactivity to our investigations of these numbers. While searching for activities a few days ago, I came across this self-checking Venn Diagram activity that I really enjoyed. (Okay, its not the one I actually found the other day, but that seems to have vanished from my history. LOL)

Here's another self-check style page for sets - I particularly like that a few of these questions require description of sets that are already in groups.

What I liked about the practice I found in my initial investigation was that it had students thinking of the numbers not ONLY in terms of "integer" or "rational," but square or even, too, so I integrated rational/integer with square and even to increase rigor in this activity.

My diagrams look like this:

Creative Workflow:
1. Place your circles on the Slide, change color properties to differentiate regions
2. Define your sets
3. Use an equation editor (I used the Daum Equation Editor Chrome app) to get images of numbers to save to laptop or Google Drive.
4. Insert numbers into slide, adding numbers to fill out the sets.
5. Duplicate slides for new groups
6. Share link to students

Student Workflow:
Students will be separated into groups of 3(ish) and directed to the Google Slides document pictured above via Google Classroom. Students will drag the numbers from the grey box onto the Venn Diagram and then add their OWN number anywhere to the diagram using a text box.

I made a separate page for each group in this one Google Slides file to keep the open/close/grade/repeat to a minimum for my groups. It could end up just being a copying situation, too, but I like the layer of potential scaffolding in place of the other groups being able to see what each other is doing.

Paper. Yeah, you could. There's less of a penalty if students need to revise their number placements this way, though. Instead of erase or start all over, its as simple as dragging.
Google Drawings. If you are working on a laptop of desktop and can edit Google Drawings (not possible on my class iPads), you could accomplish the same interactivity with a Drawings file. You would, however, lose the scaffolding I mentioned above.

Can I get the file??  Sure - make a copy. :)
