Vetted resources educators can use to teach the concepts and skills in this topic.

Description |
| Is It Odd or Even?: | This lesson will introduce students to the concept of odd and even numbers. The lesson will show that objects that can be grouped by 2's (in pairs) represent even numbers and objects that cannot be grouped in pairs (have 1 left over) represent odd numbers. The lesson will also address two-digit numbers (up to 20) to show that the place value of the number in the ones place determines whether a two-digit number is odd or even. |
| Hooray Arrays: | Hooray for arrays is an exciting way to introduce pre-multiplication skills by using repeated addition. Students will get excited when they listen to the story and shout HOORAY for ARRAYS once they play the educational game connected to the standard. |
| "Even" and "Odd" Go on a Picnic: | In this lesson, the class will be guided through solving even and odd questions involving a picnic scenario. Students will explore and discover various strategies for determining if numbers are even or odd based on whether they can be divided into two equal teams for a kickball game or whether everyone will have a buddy to pair up with on the picnic. A follow up lesson will need to be completed to address the second section of the standard involving writing an equation to express an even number as a sum of two equal addends. |
| Even or Odd Model Base Inquiry: | In this lesson, the students will explore even and odd through a variety of hands-on learning activities. Rotating center ideas are also included in this lesson. Students will utilize model based inquiry to determine and justify knowledge of number sense up to 100, comparisons of groups, and odd/even relationships of numbers up to 20. |
| Which Rectangle is Bigger?: | Students will learn how to partition rectangles into equal parts and write equations to represent the parts. They will gain a basic understanding of area from the book Bigger, Better, BEST! by Stuart J. Murphy. |
| Déjà Vu Addition, 2 plus 2 plus 2: | This lesson illustrates that when you have a rectangular array of objects, you can determine the sum of the objects by using a repeated addition equation. This builds a foundation for multiplication. |
| Odds and Evens Dodgeball: | Students will create groups of objects to determine if a number is even or odd. |
| Framing Odd and Even Numbers to Make an Even Odd Street: | In this lesson, students will determine if numbers 0-20 are even or odd. Students will begin to develop the understanding that place value (specifically the ones place) will be useful in determining whether a number is even or odd. |
| Array Addition: | This is a lesson in which students will practice making rectangular arrays and writing equations, with and without story problems, using repeated addition to find the total number of objects in each array. This lesson is designed to help prepare students for multiplication. |
| I Array + You Array = Arrays!: | An engaging activity that includes using repeated addition to find the total number of objects in equal groups and representing the total number of objects using arrays and equations. |
| Odds and Evens: | This resource helps students identify numbers as odd or even using a variety of methods including creating pairs, skip counting by two’s, using number lines, and arrays. It also leads them to understand that all even numbers can be written as a sum of equal addends and odds can be written as the sum of equal addends plus one.
This resource can be conducted as one lesson or can be spread over multiple mini sessions if needed as noted within this resource as Lesson 1 and Lesson 2.
