Common Core State Standard: CCSS.MATH.CONTENT.2.OA.A.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.
Objective
- View a 360° video and find the total number of objects in an array via addition.
Recommended Teaching Strategy
Example 360° Learning Experience
Show the video to students, navigating around so they get a sense of the scene. Have students identify the arrays (columns and rows of various items arranged rectangularly) they can see. Note arrays with each type of apple, trays of apples, and sections going down the hall. Students should identify three different arrays (with varying dimensions) and record the length and width of the arrays in their math journal, along with a sketch of the array. Once they have their sketches, students should write equations adding the number of objects in each row or column to find the total in the array. All of the totals should be recorded in their math journals.
For example, In the bottom right corner I see an array with 3 rows and 3 columns of different types of apples. 3+3+3=9. There are 9 sections of apples.
