Problem-Solving Strategy:

Draw a Picture

A grocer is stacking soup cans in a pyramid. The bottom row will have 7 cans.

Each row will have 1 can fewer than the row below it. How many rows of cans will

be stacked in the pyramid? How many cans will be stacked in all?

Draw a picture to solve the problem.

Explain how you drew your picture and how it helped you solve the problem.

Answers will vary. Sample: I know the bottom row has

7 cans, so I drew that row first. I know that each row has

1 fewer can than the row below it. So, the next row had

6. Continuing this pattern, there will be 7 rows and

28 cans in all.

Extend It The grocer removes 4 cans from the pyramid above. Then he

divides the rest of the cans into 4 equal groups and stacks each group of cans

in a smaller pyramid. Each row in each pyramid has 1 more can than the row

above it. How many rows of cans will each new pyramid have? How many cans

will be in each new pyramid? Draw a picture to solve the problem.
