Thinking Thru The Year (TTTY) focuses on developing mathematical and logical thinking. These skills are a key part of the intelligences connected with abstract thinking and problem solving required for STEM careers. TTTY is a modularized three year program in which our experts designed to hone these thinking skills. Students learn by doing as they solve increasingly complex challenges thereby building independence and persistence. Our research has shown that TTTY resulted in a significant improvement in thinking abilities, open-ended problem solving and willingness to take up cognitive challenges. The program is implemented as a series of modules offered as weekly after-school online classes through the academic year.
