Worksheet 3.25 A “Group Work” Worksheet
This is a <worksheet> which has a @groupwork attribute set to yes, along with a @label attribute to assist with the Runestone database. Note, you can also set a @groupsize attribute. When hosted on Runestone, the exercises within will be available for a group of students to submit together.
1. Multiple-Choice, Group Work.
What color is a stop sign?
Green
Green means “go!”.
Red
Red is universally used for prohibited activities or serious warnings.
White
White might be hard to see.
Hint 1.
What did you see last time you went driving?
Hint 2.
Maybe go out for a drive?
Worksheets allow for material interleaved with the <exercise> throughout.
2. Parsons Problem, Group Work.
Create a proof of the theorem: If \(n\) is an even number, then \(n\equiv 0\mod 2\text{.}\)
Suppose \(n\) is even.
---
Then there exists an \(m\) so that \(n = 2m\text{.}\)
---
Then \(n\) is a prime number.
#paired
---
Then there exists an \(m\) so that \(n = 2m + 1\text{.}\)
#paired
---
Click the heels of your ruby slippers together three times.
#distractor
---
So \(n = 2m + 0\text{.}\)
This is a superfluous second paragraph in this block.
---
Thus \(n\equiv 0\mod 2\text{.}\)
---
And a little bit of irrelevant multi-line math
\begin{align*}
c^2&a^2+b^2\\
&x^2+y^2\text{.}
\end{align*}
#distractor
Hint.
Dorothy will not be much help with this proof.
