Once everyone was ready (and I took care of the one quadratic that didn't factor - oops) they got ready. They each factored the quadratic opposite them. I started the timer at 1 minute which turned out to be too short - we settled on 1:30 for each round, then cut back to 1 minute once they were all sure of what they were doing. I also got some background music going as it seemed too quiet. They each ended up factoring 13 quadratics in a much more fun way than just giving them a worksheet and saying factor.
We spent the remainder of the period working through examples together.
Here is the homework for the next few days. I asked them to do the first box tonight.
