Math Grade 2 Quiz Determine whether a group of objects (up to 20) has an odd or even number of members-2.OA.C.3

CCSS.MATH.CONTENT.2.OA.C.3 focuses on determining whether a group of objects, up to 20 in total, has an odd or even number of members. This standard allows students to understand the basic concept of evenness and oddness. There are multiple ways to determine this, including pairing objects together (to see if any are left unpaired) or counting by 2s. Additionally, this standard introduces the idea that even numbers can be expressed as the sum of two equal addends. This understanding lays the foundation for future mathematical concepts related to number properties and operations.
