A year and a half ago, Upper School Math Teacher Stacy Mercer and Middle School Math Teacher Jeff Wolfe took a writing workshop together, bonded when they discussed classroom techniques, and became friends. Wolfe has since visited Mercer’s calculus class, catching up with students he taught six years ago, and then sitting at a desk and taking notes just like everyone else in the class. When Wolfe returned to the Middle School, he told his sixth grade students about his time with the 12th graders, and how all the math they were learning with him would be essential further down the road.

“They started sending me notes,” Mercer says. “Do we really need to know improper fractions? Yes you do!”

Finally, his second-period math class sent her an invitation: would she like to visit their class? Today she did, guest-teaching a class about integers. Wolfe gave her his notes for the day but encouraged her to teach the class her way. A great time was had by teachers and students alike — and some of those students may be taking calculus with her in the 2030–31 school year.
