## public lessons

These Public Lessons have been developed by the Noyce Foundation and are taught by practicing teachers and professional developers. These lessons have been extensively field-tested in multiple settings and refined over time, and are generally presented to an audience of participating students and observing teachers. Most draw on learning tasks developed by the Mathematics Assessment Resource Service (MARS).

## featured lesson

**Sorting Graphs, Equations and Tables**

Jacob Disston and Jesse Ragent lead a lesson and card sort activity to deepen students' understanding of the connections between different representations of functions—graphs, t-charts, and equations. Students work together to sort functions into different groupings and to "find a triple" — an equation, a table, and a graph that all make up a "family, triple, or set."
