My seventh-graders did another baseball-themed lesson today. This one was really fun: We went to the gym and took batting practice with a wiffle ball and bat. The rules were a variant on the coach-pitch munchkin league softball my little sister played in the late ’80s and early ’90s: I gave every batter seven pitches, and each pitch had three possible outcomes — strike, foul, or hit. Any contact that wasn’t foul was recorded as a hit, and any pitch that didn’t result in contact was recorded as a strike, regardless of how good or bad a pitch it was.
Each student took a turn batting while the rest of the class recorded the outcome of each pitch on a chart that included columns for the batter’s name, each of the seven pitches, the batter’s total hits, and the batter’s contact rate. After we got through the lineup, we returned to class and got out our calculators. The kids counted the hits for each batter, then divided the hits by seven (the total number of pitches) to get a makeshift batting average. Once they had calculated all of the numbers for all of the batters, they used them to calculate the class average.
This was one of those days when I ended up with 100% engagement, and the kids were spectacularly cooperative: silent in the hall on the way to and from the gym, efficient when they reached the gym — no dawdling or horsing around between batters, and I had a couple of ballplayers chasing down balls for me so I wouldn’t have any long delays between pitches — and completely invested in the math when we returned to my classroom. I was especially pleased when I noticed several of the kids helping their classmates by filling in their stats when they were batting. This was completely voluntary — they just started doing it on their own — and wound up being a great timesaver because the batters didn’t have to stop and copy down their own stats after each at-bat.
I love it when my instincts are right, and a lesson that sounds great on paper lives up to its potential.
