Turn the card over to hide the rule. Ask the students to guess the name or sorting rule represented by the circle. They can do so by picking a block from the base pile and testing for the rule by asking whether the block belongs inside the loop. The student who guesses the rule correctly is allowed to make a new rule for the next round. This helps students start thinking flexibly about data.
Students work in pairs.
The game ends when the student guesses the rule. Understanding how to make a set of limiting criteria in a rule allows you to extract specific information from a database. Games and Books Games can also help students use and understand the concept of limiting a search. As the student guesses, the information from the guesses should be written so that everybody can see the sorting rule for identifying the mystery person while it is constructed. Yes, the person is a girl.
