Math Curriculum
The foundation of the Mathematics curriculum is to provide opportunities for students to learn mathematical concepts at the conceptual level using a hands-on approach to teaching. Then, transitioning to the abstract level in order to provide all students with opportunities to learn important mathematical concepts while empowering students to become confident, resourceful and persistent problem solvers.
Fundamental Principles:
-
Math classrooms have a learning environment that are challenging and supportive.
-
Math concepts are connected through the use of multiple representations which develop an understanding and the ability to solve problems.
-
Learned concepts are demonstrated and communicated daily both orally and in writing.
