"I like your approach to math and my students are responding to it."

 - Yvonne Lynch, Special Education Teacher, New Milford, CT

"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

"This workshop was great! Hands-on, engaging, and informative. This takes thinking about math to a different level!"  Bianca Farantelli, Teacher, Syosset Public Schools, NY

"This was a great workshop! I loved how hands-on it was. It gave me lots of new ways to help my students learn and understand math!" - Melissia Kravitz, Teacher, Norwich Public Schools, CT

Our goal is to change the way people look at math! To see math in a way that creates understanding and builds concepts sequentially and systematically, with proven tools that are not only multi-purpose, they transcend grade levels providing years of use with the same student.

It is a timely and direct answer to today's need for a Tier 2 intervention that is designed to supplement the core curriculum for students in need of additional support for grades 1 to 5. This series can also work in a Tier 3 setting with slight modifications. This program also works for home educators and parents looking to provide additional support to their children in school.

We are committed to helping you meet the needs of your students and to provide materials that improve instruction and build student understanding.

One of the most requested things we hear from teachers is they wish they had some type of Flash Card that worked with the manipulatives! Well, we heard you!  Announcing the arrival of our downloadable Flash Card Series! Numerals and Shapes Recognition Cards and Game Telling Time Cards & Game Place Value Cards & Game Fraction Recognition Cards & Game
