Fun With Yekttis

In math we met these adorable creatures called Yekttis.
We are sorting them depending on certain attributes.
The shapes of their heads varies from square, triangle, diamond, and hexagon. They have either 1, 2, 3, or 4 antennas. They have either plain eyes or ringed eyes.
We are playing a game called Guess My Rule with these Yekttis. To make it a little more complicated we have played this game with two rules. Some of the Yekttis fit in both of these categories, so we needed an appropriate place to put those cards. We have also learned about the word "outlier" which is applicable when a Yektti fits neither rule.
We thought a Venn Diagram would be a great place to sort this information!
Here are a few pictures from our games today. Notice how some groups are using the labels, which are hard to see, that say rule 1, rule 2, both rules, or outliers.
