Even or Odd?

 Even or Odd?

Grade Level: 2nd

My goal for this lesson is to give second graders a sense of how to determine if a group of objects has an even or odd number of members. This can be done by pairing the objects and/or counting by 2s. If all of the objects can be paired, then the number is even. If there is one object if left over when all of the pairs are made, the number is odd.

Objective: Students will be able to categorize even or odd numbers in groups of up to 20.

Materials:

-Paper bag

-Index Cards

-Worksheets

Paper bag activity: Students will be given two brown paper bags, one labeled even and one labeled odd. Students will also be given an index with a number and corresponding dots to represent the number. 

Students will determine if the number written on the card is an even or an odd number by pairing and/or counting by 2s. If the index card displays an odd number of dots, they will place it in the brown paper bag labeled odd. If the index card displays an even number of dots, they will place it in the brown paper bag labeled even.
