That’s odd. No, it’s even! What’s not odd at all and even better are the resources from The Mailbox® for learning about odd and even numbers. Worksheets, centers, games, and chants help students identify which numbers are odd and which are even. Extend the learning with ideas and activities that couple odd and even numbers with other math skills—such as one-to-one correspondence, number sense, and skip-counting—and holidays such as Thanksgiving.
