CLAY POTTERY

Lizzie and Zela are interested in making pottery. The following chart shows how much clay is needed to make different projects.

Part A

How much more clay, in pounds, is needed to make a large bowl than a small bowl?

Instruction: Enter your answer in decimal format only (upto 2 decimal places)

pounds

Part B

Zela wants to make a set of 6 mugs. The clay only comes in 1-pound blocks.

What is the least number of blocks of clay Zela will need to make 6 mugs?

Explain how you figured out your answer.

Note: Zela knows that leftover clay from each block can be squished together and used.


Part C

Lizzie has 12 pounds of clay and wants to use all of it. She does not need to make all of the projects, and may make more than one of any project.

Describe a plan for Lizzie to use 12 pounds of clay making projects from the chart.

Show how you know she will use exactly 12 pounds of clay with this plan.


Part D

Zela is making a plan to use her 12 pounds of clay. She still wants to make 6 mugs. She also wants to make 6 small bowls.

Lizzie says:

“12 pounds is not enough to make 6 mugs and 6 small bowls. I know because I did the math.”

Zela says:

“It is enough if I make the bowls smaller!”

Make a plan for Zela to use no more than 12 pounds of clay to make 6 mugs and 6 bowls that are smaller than the bowls in the chart. Zela does not need to use exactly 12 pounds, but she would like to use most of the clay.

In the plan, state how much clay she should use for each of her smaller bowls. Her bowls should all be the same size.
