This document outlines a math lesson plan that focuses on multiplication and arrays. The lesson includes fluency practice problems involving adding and subtracting by 2 and group counting. During the concept development, students relate equal groups to arrays by exploring a problem about lemonade production. They draw an array and count circles in rows to see the relationship between multiplication and adding equal groups. The lesson concludes with a problem set, debrief, and exit ticket to assess understanding.

equals 6.

7. Application Problem
(5 minutes)
Jordan uses 3 lemons to make 1 pitcher of lemonade.
He makes 4 pitchers. How many lemons does he use
altogether?
(Use the RDW process to show your solution)

8. Application Problem
(5 minutes)
4 X 3 = 12
Jordan uses 12 lemons altogether.

9. Concept Development
(30 minutes)
Problem 1: Relate Equal Groups to Arrays
Look back at Jordan’s lemons. Compare the way his lemons are
organized with the groups of 3 circles on your template.
Let’s call a straight line going across a row. Use your blank paper to
cover all but the top row.
Uncover 1 row at a time in the picture. As you uncover each row, write
the new total number of circles to the right of it.

10. Concept Development
(30 minutes)
At the signal say the total number of circles you
counted.
Take 10 seconds to find how many rows of 3 you
counted. At the signal say how many.
True of False: 10 rows of 3 circles equals 30
circles?

11. Concept Development
(30 minutes)
10 x 3 = 30
Use the picture on your template to talk with
your partner about why this equation is true.
We call this type of organized picture an array.
