To introduce this concept of odd and even numbers, we talk about even numbers being the sum of two equal numbers. Or, you can say the parts of an even number can be divided into two equal groups. Odd numbers can be taught as numbers that cannot be grouped into two equal parts. You might say there is an “odd man out.”

**Stand Up/ Sit Down** This is a simple game that requires no preparation. After reviewing odd and even numbers, give the students a number. Instruct them to stand up if the number is even and sit down if the number is odd. For added practice, have a volunteer explain how he or she knows the number is odd or even.

**Post-It Notes** Write a number on enough Post-It notes for every student in the class. Give each student a note. Create two sections on the board labeled odd and even. Have a group at a time place their number in the correct category.
