- Mathnasium helps build confidence by creating a student-specific plan for kids in grades 2-12. Students can attend the one-hour sessions every day if they’d like, and the session starts when they show up, so it is extremely flexible. The space is open, airy, and quiet, which makes it easier for kids to focus. The reward system they’ve created makes kids work harder and find motivation to work a bit harder in this tough subject. Students do not receive extra work outside of these sessions, which is a bonus for math-reluctant kids. My child looks forward to going each week.
