Football Review: Teams
Team one:
1. Michael
Team 2:
1. Chris
2. Kevon
2. Eric
3. Kelvin
3. Barry
3. JerTayvious
Football Review: Rules
•
You will work with your team to get the right answer
•
When the question is read, you will have 25 seconds to think of and write down your answer
•
The team that that raises all their paddles with the same answer first answers first. Mr. D will
randomly select a player’s # to answer. The player can “double the distance” by explaining why.
If they get it right, they move twice as far (“10 yards”). If wrong, just 5 yards.
•
(interception) If the team gets it wrong, the other team can answer
•
(fumble) If they don’t know/get it wrong, Mr. D will call out a random #; the first person who
raises their hand for that number (either team) can answer in 10 seconds.
•
If they get it right, they move a spot (5 yards)
•
If the person who answers first gets it wrong, the other person can answer; if they don’t know or
get it wrong, we move onto the next question
•
4 points equals a touchdown which equals one point. Then we restart in the middle and the
team that didn’t score will starting answering.
Football Review:
Penalties
•
There is no talking when someone answers a question, unless it’s
a fumble and the person is asking within 10 seconds. Penalty:
move back one spot
•
There is no talking between teams. Penalty: lose a point; if no
points, one strike
•
All class rules apply (no standing, throwing, disrespectful
speech). If you break them, you will leave your team and work “
on the sidelines” on an assignment independently and silently. If
you continue to be disruptive, you will receive a detention
•
If three people break the rules (three strikes), we will all work on a
review sheet silently
Football Review:
Encouragement
•
You may encourage your teammates between
questions but must be silent once Mr. D raises his
hand for the next question.
•
You may contribute the answer quietly during a fumble
•
The team that wins gets a ticket for each “touchdown”
scored and one bonus point.
•
The second team gets a ticket for each “touchdown”
scored.
