An immersive, five-day building experience that springs out of Mark Day School’s long standing collaboration with the world-renowned Tinkering School in San Francisco, this program seeks to empower students by introducing them to real tools and challenging them with these four goals:

1. Make mistakes and learn from them
2. Build something bigger than themselves
3. Collaborate and make new friends
4. Try harder than usual

Each week-long session at Summer Tinkering at Mark Day is a student-centered experience during which students imagine, design and build incredible large scale creations out of wood under the watchful guidance of caring and experienced Mark Day faculty and staff. We have sessions for 7-11 year olds (and one special session for 10-13 year olds!) Each week begins with a surprise theme that provides the structure and story for the week. Past themes have included Harry Potter, where students designed and built the Hogwarts Express steam train, and Pirates where students spent the week building a GIANT pirate ship and an island to hide their treasure on!

Camp runs from 9:00am-3:00pm each day. Drop off is 8:45-9:00am. Pick up is 3:00-3:15pm. Extended care available as well.

Camp fee assistance is available for Summer Tinkering at Mark Day School. We offer assistance on a pay-what-you-can basis while funds last. All families will have the option to request camp fee assistance during the registration process in UltraCamp.

At KidStock, we devote all three weeks of our summer day camps to putting on a show! Campers receive parts during the first few days, then work to develop their characters, master their dances and perfect their featured singing parts. Between workshops, campers have plenty of time for free play, as well as making new friends! On the second to last day of camp, it's showtime--complete with lights, costumes and professional sound. Family and friends are invited to watch as the campers reveal the product of their hard work. On the final day, a talent show gives kids the chance to display new-found confidence to friends new and old.

In our performing arts programs, every child receives a part in the play, and we challenge all our students to grow and learn as they help tell the story and make new friends.

Grades: K-8
Dates: June 20-23 / June 26-30 / July 3-7

Rock out your summer days with other young musicians! Learn to play your favorite current songs or write an original tune. Maybe this is the place to start a band? For existing bands, this is a great way to keep your band going strong over the summer. 

This camp is a great place to be for students who want to learn about studio recording techniques. Students will get the opportunity to record music just as their favorite musicians would in a real recording studio! In addition to rehearsing their songs, students will learn all about instruments, mixing and using effects, as well as all the preparation necessary to make a good recording. At the end of the week, students will receive a professional quality demo of all their recorded songs.

Vocalists and all instruments are welcome!

All writing is creative, isn't it? All writers need to learn skills and practice their craft regularly. Join Ms. Kirk for a morning workshop that will leave you feeling equipped and inspired. The day will begin with exercises and prompts tailored to your skill level, ones that will prepare you for the challenges of academic writing. You’ll learn everything from proper punctuation and how to choose the perfect word, to responding thoughtfully to a question or prompt in paragraph or essay form. The second half of class is all about choosing what’s right and fun for you to pursue as a writer. Poetry? Personal Essay? Article? Short story? Finding the right medium will help you develop your unique voice and make excellent use of your imagination, which is always in need of its own “boot camp”! Writers will set goals and receive daily feedback from Ms. Kirk.
