The students played Guess my Rule with our invesitgations shape cards. One student would think of a rule and then put all the cards that fit that rule on the blue piece of paper, their partner had to guess what the rule was.
I found this great printable from Crazy for First Grade and thought it would be perfect for an individual assessment. They covered up the rule part and the class had to guess what their rule was.
