Solve on your whiteboard. Show your work. Math Message Solve on your whiteboard. Show your work. There are 6 rows of chairs. There are 4 chairs in each row. How many chairs are there in all?

Math Message Discussion How did you solve the problem? Some possible methods:

Multiplication/Division Diagram Another way…

Using the Diagram Sammy and Chris are setting up chairs for the 4th Grade Talent Show. There are 32 chairs. Mrs. Morales asked them to arrange the chairs so that there are 4 rows with the same number of chairs in each row. How many chairs should Sammy and Chris place in each row?

Let’s try another one! Mr. Frank is setting up chairs for the Board of Education meeting in the cafeteria. There are 43 chairs. Mr. Marold asked Mr. Frank to place 7 chairs in each row. How many rows of chairs will there be?
