You can access this page in I-Learn. It's the third bulled (Class Activities) on the home page.

Pre-Class Chatter

Feel free to turn on your mic and chat with people, or use the zoom chat if you prefer. You can also use Jamboards to chat with your group members.

Rapid Recall (Sometimes Jivin' Generation)

We start each class with a few brain pushups. Both recall and generation serve the same purpose, namely helping your brain form and grow pathways to connect information.

1. True/False: It is OK if I don't get everything right the first time I attempt it.
   • The solution is a possible class theme song: Try Everything
2. Give the component form of a vector that points from $(0,3)$ to $(4,0)$.
3. Find the distance between $(1,2,0)$ and $(0,0,2)$.
4. Construct a rough sketch of the points $(1,0,3)$ and $(0,2,3)$.

Break Out Rooms

1. In 3D, plot the points $(1,2,3)$ and $(-2,4,-3)$.
2. Find the distance between the two points $(3,5,-2)$ and $(-1,6,4)$. Then find the distance between the point $(3,5,-2)$ and an arbitrary point $(x,y,z)$.
3. Find the component form of the vector that starts at $(4,-3)$ and ends at $(2,-2)$.
4. Give a unit vector that points in the same direction as the previous. Then give a vector of length 3 that points in the same direction.
5. Plot the vector valued function $\vec r(t) = (-2,1)t+(4,-3)$ for $0\leq t\leq 3$.
6. Give the component form of a vector that points from $(1,2,3)$ to $(-2,4,9)$.
7. Give a vector equation of the line that passes through the point $(1,2,3)$ and $(-2,4,9)$.
8. Use the law of cosines to find the angle between the vectors $(-2,1)$ and $(1,3)$.
9. For this one, have everyone in the group use chalk at the same time. In 3D, plot the points $(1,2,0)$, $(1,0,3)$, $(0,2,3)$, $(1,2,3)$, $(-2,4,-3)$.
