CAASPP Grade 5 Math - Performance Task

Which project needs the most clay?

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.

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.

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.

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

Zela does not care about using exactly 12 pounds, but she does want to use as much of the clay as possible.
