Math Philosophy

At Seattle Girls’ School, math is about more than just getting the right answer—it’s about making sense of the world through patterns, logic, and collaboration. Our approach encourages students to take risks, ask questions, and explain their thinking, knowing that mistakes are part of how we grow. Math class is a space for discussion, discovery, and persistence, where students learn to see themselves as capable problem-solvers. We focus on real-world applications and multiple strategies, helping every student build a strong foundation—and a sense of confidence that carries beyond the classroom.

Four Principles of Math at SGS

List of 4 items.

  • 1

    Math is for everyone
    Girls and gender diverse students are math capable and deserve hard math; it’s our (teachers’, students’, families’) job to help each other believe that learners have a significant capacity for deep understanding.

  • 2

    Growth through Struggle
    Persevering and struggling productively are a part of the learning process; contributions are more valued for their reasonableness than for their accuracy.

  • 3

    Math as a conversation
    Collaborating, vocally agreeing and disagreeing, asking questions, reasoning, listening, understanding the thinking of others in community develops our deep understanding of math concepts.

  • 4

    Risk taking is necessary 
    Taking risks (sharing an idea when you’re not sure it’s correct, disagreeing publicly, trying something uncomfortable or challenging, admitting when you don’t know, asking questions to further your own and others’ understanding, struggling productively) strengthens our learning community.
