Introductory Activity (Warm-Up):
Using overheard projector and unifix cubes, students elicit ways to create different arrays for a teacher specified number. |
Lesson:
Have the students open Excel and format Sheet 1 using the directions (file 1) on using Excel. Create multiple worksheets in the workbook and rename each sheet with a specified number. Demonstrate how to highlight, color, and label the cells. Assign each of the students a number and have them find all of the arrays that can be made for that number. If a student finishes, you can assign them another number and have the students create the arrays on the renamed worksheets. At the end of the session, have the students save their document so that they can work on it in the classroom when they have time.

Reteach:
To be determined by the classroom teacher based on student needs
|
Extension:
Have the students color the arrays that have the same factors a different color from the others to show their relation.
|
Guiding Questions:
Does every number have more than one array?Is there any relation between the size of the number and the number of arrays that it has? What can you tell me about a number that has an array with 2 as one of the dimensions? Can you think of a number that would have an array in which the dimensions would be the same for the length and width?
|
Summary Questions:
What did you find out about the numbers that have arrays with 2 as one of the dimensions?What number would only have 1 array? Did the size of the number have an effect on the number of arrays?
