Dear LOR user,

Thank you for being a big part of this community. To better support the initiatives around open educational resources in the state of Michigan, all resources on the Michigan Virtual Learning Object Repository (LOR) are being moved to #GoOpen Michigan (link is external) on September 30th, 2018. During the transition, our LOR will be moved to an archived state, not allowing new user registration or new content to be added. An email with more details was sent to registered users of the LOR in September. To make use of the great resources on the platform, we encourage you to create an account and add your own new resources to the #GoOpen Michigan platform (link is external).

CCSS.MATH.CONTENT.2.OA.3

Work with equal groups of objects to gain foundations for multiplication.

Description

Determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends.

This unit revolves around the math curriculum Math Expressions for 2nd grade Unit 1: Addition and Subtraction within 20.

The teaching and learning for this unit will be both face to face, as well as online. For young students, it is important to find the proper blend of both types of teaching/learning. Students will be not only learning which numbers are odd and even, but how to identify them and explain how they know they are odd or even.
