Lesson objective: Identify even and odd numbers by pairing objects or counting by twos.

This lesson helps to build understanding of how to identify even and odd numbers by utilizing the strategies of counting by twos and pairing objects. A game with counters is used here because it supports the development of counting by twos and pairing objects as strategies for identifying even and odd whole numbers. This work develops students' understanding that we can count by twos or pair objects to determine if there is an even or odd amount in a group.

Students engage in Mathematical Practice 7 (Look for and make use of structure) as they decompose each number with counters by counting by twos or making pairs to determine if a number is even or odd.

Key vocabulary:

• even
• odd
• pair
• decompose

Special materials needed:

• counters (or something they can model their counting with as they play the game)
