Color Your Summer with D-E 360°

For Summer 2025, D-E 360° has designed a portfolio of programs to deliver on very specific interests expressed in our community. We’re building on our summer theme, Kaleidoscope, to provide a scope of programs through which learners across age levels may acquire new knowledge and develop skills. Check out our line-up of programs, ranging from music, theatre, and chess to sports, STEM, and computer programming!

Here’s to this year’s Math Days! Math Days is an all division event where all D-E students receive the same problem to illustrate and solve. Upper School students came down to the Lower School to support problem-solving, and it was a wonderful moment for learning for all. See how the students visualized their thinking and brought math to life.
