Guess my Rule

Our overview of third grade math continues with data collection and representation. Today and yesterday we played a game called Guess My Rule. I called people to the front of the class who all had something in common. The children were challenged to figure out what they had in common and invite others to the front who also "followed the rule." Mathematicians look for patterns and that includes finding similarities and differences.

The children took the data we collected during the game and represented it visually. For example, yesterday 11 children were wearing long sleeves and 8 children were wearing short sleeves. Some children showed this data by drawing 11 shirts with long sleeves and 8 shirts with short sleeves. Other children showed the data using a bar graph. It was exciting to see how many ways children could tackle the task.

You can play Guess My Rule at home! Gather a collection of objects. Pull out certain objects that have something in common. The children can guess what your rule is. Better yet, they can choose the rule and you can guess what they are thinking. You can even play this with numbers, book characters, practically anything you can imagine.

Have fun! :o)
