Time length: 15-20 minutes
This product contains labels for brown bags (rational, integer, whole, and natural numbers), 10 numbers, recording document, and a reflection page.
Students can work in pairs or small groups. Students need to determine what is the best set or subset that each number belongs to.
Students may have to simplify the numbers first, before determining what set the number belongs to.
After students have placed the cards in the appropriate bag, they will have to complete a few questions. They will need to define key-terms and provide examples. They will have to describe the process they took to determine which set to place each number and compare strategies.
At the end of the activity, students can reflect on their level of mastery.
