We Are Learning To…
Attend to precision in definitions, reasoning and discussions in a math task.
Understand the sixth Standard for Mathematical Practice: Attend to Precision.

PrecisionLinguistic
Communicating precisely by using clear definitions and symbols
NumberExpressing numerical answers with a
degree of precision appropriate to the
context

LaunchYou cheered on the Packers and during the Super Bowl collected a stack of 64 commemorative cups. You begin to wonder how tall is a stack of 64 cups?
![Page 6: February MTL Meeting February 8 th and 10 th Kevin McLeod Hank KepnerMary Mooney Connie LaughlinBeth Schefelker Precisely My Dear Watson.](https://reader035.fdocuments.in/reader035/viewer/2022081603/56649f055503460f94c1aed5/html5/thumbnails/6.jpg)
ExploreUse the stack of cups to brainstorm ideas that would help to find the height of sixty-four cups.
What ideas do you have to consider?height of cup height of rim nesting cupsmeasurement tools

Here’s the challenge…Use what you know about a standard piece of paper to help you determine a process to find the height of 64 cups.
Discuss your findings with your group. Come to an agreement on a solution process.

Coming to a conclusion…
Record your thinking, step by step, using pictures, words, and numbers.
Choose one representation to put on chart paper and post around the room.

Mathematically proficient students
communicate precisely to others.
Read the Standard for Mathematical Practice #6
What does the standard say that students need to be able to do?
What would you expect to surface on student work that would exemplify this standard?
![Page 10: February MTL Meeting February 8 th and 10 th Kevin McLeod Hank KepnerMary Mooney Connie LaughlinBeth Schefelker Precisely My Dear Watson.](https://reader035.fdocuments.in/reader035/viewer/2022081603/56649f055503460f94c1aed5/html5/thumbnails/10.jpg)
Gallery WalkTake a gallery walk around the room
analyzing each tables solution as displayed on the poster.
Think about how the work displayed connects to the ideas discussed in Mathematical Standard for Practice #6 Attends To Precision.
Return to your table group. Discuss the features in the work that connected or didn’t connect to the standard.

Standard for Math Practice #6
![Page 12: February MTL Meeting February 8 th and 10 th Kevin McLeod Hank KepnerMary Mooney Connie LaughlinBeth Schefelker Precisely My Dear Watson.](https://reader035.fdocuments.in/reader035/viewer/2022081603/56649f055503460f94c1aed5/html5/thumbnails/12.jpg)
What did you notice?
What did you notice about the approaches tables used to find a solution to the task?
In what way did you notice the Standard “Attend to Precision” surface on the charts?
![Page 13: February MTL Meeting February 8 th and 10 th Kevin McLeod Hank KepnerMary Mooney Connie LaughlinBeth Schefelker Precisely My Dear Watson.](https://reader035.fdocuments.in/reader035/viewer/2022081603/56649f055503460f94c1aed5/html5/thumbnails/13.jpg)
In what way would these directions have affected the Standards for Mathematical Practice?Stack enough cups that is
approximately the same measure of the width of a standard piece of paper (8.5” by 11”).
Stack enough cups that is approximately the same measure as the length of a standard piece of paper.
Discuss your findings with your group. Come to an agreement on how you will record your results.
![Page 14: February MTL Meeting February 8 th and 10 th Kevin McLeod Hank KepnerMary Mooney Connie LaughlinBeth Schefelker Precisely My Dear Watson.](https://reader035.fdocuments.in/reader035/viewer/2022081603/56649f055503460f94c1aed5/html5/thumbnails/14.jpg)
What is needed to make this more precise?C = cupsR = rim
C + 14R = 11C + 9R = 8.5
5R = 2.5R= .5
c + 4.5 = 8.5 64 cupsc = 4 inches 4 + 63(.5) = 35.5
![Page 15: February MTL Meeting February 8 th and 10 th Kevin McLeod Hank KepnerMary Mooney Connie LaughlinBeth Schefelker Precisely My Dear Watson.](https://reader035.fdocuments.in/reader035/viewer/2022081603/56649f055503460f94c1aed5/html5/thumbnails/15.jpg)
An excited student says…Looking at her paper, Beth exclaimed,
“Hey, 5 rims is about 2.5 inches, that is so cool, you want my paper now?”
Has she found a solution to the original question, “What is the height of 64 cups?”
What feedback would you offer Beth to encourage her to continue her work in finding a solution as well as pushing her to speak and write precisely about the mathematics.

Standard for Math Practice #6Thinking about “Attends to Precision”, what
teacher moves would help students’ understanding of precision?

SummarizeIn your group, record your understanding about Attending To Precision.
What new ideas emerged as a result of the work we did today?
