# Day 66: Racecar Math

I didn’t have good feelings about only spending two days on the slope equation in algebra. I had originally planned to print off a few Pizzazz worksheets and spend another day practicing. I didn’t feel good about that either.

Instead I looked over at my bookshelf and saw the remote control monster truck I bought last year. It ended up being a good move…

Both Dan and Andrew have posted about this sort of review. I tweaked it a bit and used it as a way of getting students to practice a concept more without the monotony of back to back days of book work and worksheets.

I picked this up from Target for \$14.99 last year.

After our opener I threw this up on the board

I explained there were two types of problems; individual and group, each slide would indicate the type of problem. For group problems they would work on the large whiteboards on their desks.

I gave students about a minute for each problem, once they had an answer they stood up. Only one person from each group could be standing at a time.

I paced around, looking at students work. After the timer I read out all the answers I saw and called up the standing students with the correct answers to drive the car. Those who were incorrect worked with their groups to correct the mistake.

Students drove the car in a 25 foot L shape the ended with this:

Each box was worth points equal to its number. If they back the car into the box it was worth double points.

All my students were on board today. The only downside to this is we spent about equal time driving the car as we did doing math. I will fine tune the process in the future.

Best part of the day… Geometry came in begging to drive the car today. They had been hearing about it all day I guess.
