Mathematics

Seeds of Algebraic Thinking are sub-conceptual resources coming from life experience that students call upon when responding to mathematical prompts. This site includes resources students could activate when thinking about groups and sets, equality, proportionality and ratio reasoning, and functions.

This site offers professional learning materials for elementary teachers and teacher leaders, including a Responsive Mathematics Teaching Toolkit and Lesson Planning and Analyzing Tools.

This site provides three online activities focused on covariational reasoning as a foundation for middle school students to build more abstract algebraic knowledge. These tasks provide students with opportunities to understand static points, understand dynamic points, and make sense of different amounts of change.
