500
Draw an array, an equation, and sentence (use factors and products):
Ms. Jackson has 5 rows of desks. Each row has 10 desks in it. How many desks does she have total?
5 x 10 = 50
I know Ms. Jackson has 5 rows, so I put that as the first factor. Then I knew that each row had 10, so that is the second factor. Ms. Jackson has 50 desks because that is the total, the product.
