Welcome to the laboratory. Here your child can count and color as they decide if these numbers are odds or evens.

Let's get to the math lab and figure out these numbers. Your second grader will do counting, coloring and writing while learning about odd and even numbers.

Help your second grader determine whether numbers are odd or even with this bright, engaging game board. Practice counting and number sense, too!

What are odd and even numbers? This simple worksheet makes an example of numbers your child already knows to help them easily identify other odd and even numbers.

In this Halloween maze, follow the even numbers out of this scary graveyard. But watch out -- there are odd numbers waiting to trip you up!

Can your second grader track down the odd numbers, and write them on sections of the caterpillar's body?

Your learner can play their own World Cup, and practice skip counting by 2s at the same time!

Build a solid foundation for multiplication by helping your second grader practice recognizing number patterns.

These odd and even numbers are all mixed up! Learners decide which numbers are odd and which are even, and then color the circles accordingly.

Laminate and display this puzzle to encourage students to think deeply about how each group of circles is the same and different. This works as a great hook when introducing the concept of odd and even numbers.
