Addresses Virginia Math SOL 5.3 and CCSS.MATH.CONTENT.4.OA.B.4
These cards give students the opportunity to engage in higher order thinking and deep discussion. On each card, there are four numbers. Students decide which one number does not belong with the rest, (i.e. which is the oddball) and justify why they think it does not belong. There can be more than one correct answer for each card.
This can be done whole class, as a Number Talk, as a scoot, as part of a center, or even individually.
There are 16 cards and a recording sheet included. There is an answer sheet based on how I view the cards; again, these may not be the only answers.
- prime numbers
- composite numbers
- even numbers
- odd numbers
- square numbers
