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 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.
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. )
