The Activity

Put them randomly on the students chairs before they arrive in class. After they
come in and find their cards, tell them the following:

Today you are going to be one of the fractions that lives in Fractionville. You will
need an ID card which you found on your chair. The ID card has your name
(for example, 3/4) and a picture ID. You belong to a family of 5 equivalent fractions.
Your task is to find your family members and sit down with them. When you are together,
the godmother or godfather should stand up!

After the students are in their groups and find out who their godmother or godfather is, the fractions in lowest terms stands up!
