HOT SEAT DIRECTIONS:
Teachers will have each problem taped to the desk
using packing tape. (I run the problems in 3-4
different colors EX. Pink, Yellow, Blue). If the student
starts at a pink desk they will only move to desks
with pink problems, etc.
I will play a song and the students will have the
length of the song (I will shorten some songs) to
solve the problem they are working on. If they do
not finish, they still will move on and will then go
back to that problem when they have time.
Provide them with an answer document to show all
work. At the end of the activity and we will discuss
the most missed problems.
All set of problems are the same, they are just run
on different color paper to help save the students
from fighting over certain desks. 
A pen of bulls has 8 black bulls, 4 brown
bulls, and 6 white bulls. Riders
are randomly assigned one of the

that a rider will get a white bull?
Write your answer as a ratio,
decimal, and percent.
The rodeo doctor wanted to find out how
many of the bull riders were competing today
with serious injuries. There were so many
competitors that he did not have time to visit
all the bull riders. He visited 30 of the 400
riders. He found that 6 out of the 30 were
competing with stitches or fractures. Based on
this information, how many would you predict
out of 400 would be competing with stitches or
fractures?
