Mathematics
From developmental math to calculus and beyond, Smarthinking delivers.
Using our proprietary virtual whiteboard for live, real-time collaboration, tutors guide students through solving math problems. Smarthinking’s tutors do not solve the problem for students. Instead, tutors use a problem-solving based teaching style to help students learn underlying math concepts. In this way, students learn to handle future assignments on their own.
Except where noted, mathematics and statistics tutors are available 24/7 during the standard school year. See the Hours of Service schedule for additional details.
