Content Standards: Standard 2.OA.3 Determine whether a group of objects (up to 20) has an odd or even number of members, (for example, by pairing objects or counting them by 2s) .Write an equation to express an even number as a sum of two equal addends. Standard 2.OA.4 Use addition to fnd 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.

End of Unit Competency and Language Supports

By the end of Topic 2 students will be able to explain the relationship between arrays and repeated addition when working with equal groups. Language Functions and Features: Describe data and/or steps to solve problems using: ● Mathematical terms ( even, odd, array, row, column, skip-count, equation ) ● Visuals ( ten-frames, bar diagram, pictures, charts ) to support approach, solution, and/or extract information ● Conditional clauses ( when, if ) to extend conjecture (eg. When I make pairs, there are none left. )
