The activities in this resource are intended to be used as a warm-up (or wrap-up) activity in the math classroom. They are designed to get students engaged and thinking mathematically.
They can be used at any time of the year, or in conjunction with a concept being covered in class to help further understanding. Concepts covered include, odd and even numbers, multiples, prime and composite numbers and more.
For these activities, students need to determine which number is the "imposter", or which one doesn't belong.
This booklet includes 10 separate activities with an answer key.
