As a math teacher, I regularly encounter students who don't believe they're good at math. One of the wonderful things about being a teacher is having the opportunity to help students overcome that belief. Mathematics can be challenging, but no student is incapable. When I meet with a new student, I take time to understand how the student best learns and if there are any concepts they are struggling with. When I teach a new concept to students, I explain it in two or three different ways because not all students approach things in the same way. I encourage students to become more confident in their work by encouraging questions, practicing with students, and helping students overcome barriers in their understanding.
