Idea: Ask for a
challenger.
The other day I had a few minutes left in class so I decided to
challenge a student to a game of buzz. (That is the one where
you count back and forth and substitute B-U-Z-Z for all the 7's or
multiples of 7. I asked for a volunteer to take me on and
offered 10 points extra credit to the student who could beat me.
It woke up the rest of the students as they watched the "challenger"
strive to stay in the game.
The next time I do this game I will award the 10 points to the
student for either "winning" or "reaching 30." For more
advanced classes you can make the goal higher (like reaching 50 or
100).
Another variation would be to give them 5 points for trying or 10
points for winning.
If that student wins you could let that student become the new
"champion" and defend their title once a day. You could award
a candy bar or something other than points so that the student
doesn't earn their grade just by being the "buzz master."
