"Teach 4 Mastery training with Dan Sinclair was one of the best professional development trainings we have had in years. After two full days of training, our lower, middle and upper school teachers were excited, energized and ready for the start of the year! Closets have been cleaned out to make room for what we know will be the most useful manipulatives of all time! We can’t wait to see the students’ responses as they embark on a new and exciting math journey."
- Megan McGowan, M.S., Head of Lower School, Jemicy School
"I like your approach to math and my students are responding to it."
