I am always looking for new ways to make learning a little more entertaining. I was looking for something additional to do during our geometry unit because it is so vocabulary rich. So I created a Bingo game, well really a "Bing" game to help the kids review some of the key vocabulary in the unit. This covers measurement terms, polygon terms, 2-D and 3-D terms, etc.
It includes 6 different boards for the kids so that you get some variety. It also includes the call out cards for the teacher. As a variation or a challenge, consider giving the attributes of the words that are on the teacher call out cards versus the actual term. For example, "I have four equal sides and four equal sized angles" This is a fun challenge and a little informal assessment as to how they are doing with the different attributes. Enjoy!
