Equal Groups Multiplication Song | Repeated Addition Using Arrays

Video: Equal Groups (Repeated Addition Using Arrays)Grade Levels: 2nd Grade - 3rd GradeFor 2nd Grade, using repeated addition to find the number of objects in an array sets the foundation for multiplication. By representing groups of objects in rows and columns, students can visualize and conceptualize multiplication.In 3rd Grade, students learn to represent multiplication through arrays showing equal groups, while also spiraling back to review the use of repeated addition and it's relationship with multiplication. Equal Groups: Repeated Addition Using Arrays Song is aligned with the following Common Core standards:2.OA.4Use 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.3.OA.1Interpret products of whole numbers, e.g., interpret 5 × 7 as the total number of objects in 5 groups of 7 objects each.
