Write an equation to express an even number as a sum of two equal addends. - **2.NR.3.2**: Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends. ## Georgia Milestones coverage No Georgia Milestones blueprint cites this standard. ## The same standard across grades - Kindergarten, K.NR.3: Use place value understanding to compose and decompose numbers from 11–19. https://georgiahomeroom.org/standards/code/K.NR.3.md - **Grade 2, 2.NR.3 (this standard)**: Work with equal groups to gain foundations for multiplication through real-life, mathematical problems. - Grade 5, 5.NR.3: Describe fractions and perform operations with fractions to solve relevant, mathematical problems using part-whole strategies and visual models. https://georgiahomeroom.org/standards/code/5.NR.3.md - Grade 6, 6.NR.3: Solve a variety of problems involving whole numbers and their opposites; model rational numbers on a number line to describe problems presented in relevant, mathematical situations. https://georgiahomeroom.org/standards/code/6.NR.3.md Source: Georgia Standards of Excellence, published by the Georgia Department of Education at case.georgiastandards.org.
