# Division as Grouping (Number & Operations): Math Lessons for the SMART Board™/2-3

### Product Description:

Using the “Division as Grouping” Notebook file, explain division as making groups of equal amounts from a larger amount. Using counters and looking at problems and number sentences in the Notebook file, work with the class to explore division as grouping! Complete with a teacher's page PDF, a "Grouping" reproducible, and a launch-and-learn Notebook file, this mini-lesson helps to achieve the following learning objectives: • Represent repeated subtraction (grouping) as division.

## Teaching Tip:

This mini-lesson meets the following Common Core State Standards for Mathematics: 3.OA.2: Interpret whole-number quotients of whole numbers, e.g., interpret 56 ÷ 8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56 objects are partitioned into equal shares of 8 objects each. 3.OA.3: Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities. This mini-lesson also meets the following NCTM Standards: • Understand situations that entail multiplication and division, such as equal groupings of objects and sharing equally. • Understand various meanings of multiplication and division. • Understand the effects of multiplying and dividing whole numbers.
