# Math Curriculum

We rely on materials from *Investigations* to deliver our math program in kindergarten through Grade 4 and use materials from *Connected Math 3* (CMP3) to teach the content in Grades 5 through 8. Additional information about each program can be found at the links below.

##### Math Vision Statement

**Goals:**

- Help students develop the knowledge, skills, and confidence to use mathematics as a tool for solving problems that occur within the confines of math class and beyond.
- Prepare students for success in each successive stage of their educations, including secondary mathematics.

**Principles:**

- Mathematical understanding is ongoing and develops when a learner reflects on prior knowledge, forges new connections between ideas, and communicates his or her thinking.
- Students are curious and natural problem solvers; they actively participate in their own learning and recognize that mistakes are part of the learning process.
- Mathematics curricula should feature challenging problems that promote reflection and communication. Tasks should be meaningful and relevant to the students and motivate them to link mathematical skills to their underlying concepts, formulate strategies, and justify their solutions. Individual lessons within curriculum units should be connected in ways that help students consider ideas from multiple perspectives and make sense of important mathematical relationships.
- Teachers develop students’ mathematical understanding by facilitating whole-class discussions, providing relevant information, sharing mathematical conventions, and suggesting alternate methods.
- Discussions are a critical and core element of math class as they provide students with valuable opportunities to explain particular methods, analyze errors, and compare and contrast different approaches to the same problem. All students have the right to have their ideas heard and considered and are expected to actively respond to the reasoning of others.
