Welcome to Saturday Math, a professional learning community where teachers, administrators, curriculum enthusiasts, and other education colleagues come together to do, learn, and talk about mathematics. Designed for pre-K–12 educators, this program meets throughout the school year to support deep engagement with math and for reflective conversations about the work of teaching. While we encourage participation across all of the sessions, educators are welcome to drop in to any session.
Each facilitated session includes two or three rich mathematical tasks and structured discussions about our practice as math educators. Topics may focus on content (e.g., Connecting Fractions, Decimals, and Percents) or pedagogy (e.g., Using Mathematical Routines), always with an emphasis on making connections to your unique role—whether you’re a teacher, coach, administrator, or another education professional.
You’ll leave each session with new insights and the support of a vibrant community committed to growing together in the work of mathematics education.

Data and Statistics |
On campus |
Through hands-on activities and collaborative discussions, participants will explore making sense of variability, interpreting distributions, and drawing informed conclusions from data. Whether you are new to teaching statistics or looking to deepen your practice, this session offers actionable strategies to bring data to life in your classroom. |

Functions |
On campus |
This session is intended for mathematics educators to come together in a collaborative environment to interpret and construct graphs of functions. Through engaged discourse, participants will explore how these visual representations connect to equations, tables, and real-world contexts. Educators will deepen their own content knowledge and understanding of key concepts such as slope, intercepts, transformations and behavior across multiple function families (linear, quadratic, exponential). At the end of the session, educators will have proven strategies that will help them analyze student work, identify misconceptions and support students in their classrooms to build conceptual understanding around functions. |

Equality vs. Inequality |
Online |
This session is intended to deepen our connections between equality and inequality. We will discuss the meaning of the equal sign and how students’ understanding of equality and inequality evolve across grade bands. Through multiple tasks and discussions, we will examine how students develop understanding of equality as a relationship rather than an operation. We will look at how inequality extends that understanding through comparison, reasoning, and modeling. Emphasis will be placed on exploring multiple representations and how we can bridge our own understanding to our classroom instruction. |

Multiple Representations of Inequality |
On campus |
This session will examine the progression of inequality concepts across multiple grade bands and highlight instructional practices that deepen mathematical understanding and connections. We will explore how students’ reasoning about “greater than,” “less than,” and “not equal to” evolves into solving and interpreting inequalities, graphing solution sets, analyzing functions, and modeling real-world situations with constraints. |
