Can a 3D printer replicate a real-life playground? Flint Hill Middle School Math teacher Erin McKavitt sought to answer this question with her Pre-Algebra classes this year. Last fall, in partnership with KOMPAN, the School opened three new, state-of-the-art playgrounds for its Lower and Middle School students. And inside the classroom, students had the opportunity to experiment with new 3D printers purchased as part of the ongoing expansion of Flint Hill’s Innovation program. Combining math and engineering concepts with a healthy dose of fun, Ms. McKavitt’s Pre-Algebra classes measured the new Middle School playground, scaled it down, created 3D digital models of it, and used the School’s 3D printers to produce replicas of its structures.
