About CBMP Lessons

Our lessons are structured to engage students in inquiry around questions that have personal significance for them and are connected to their school and local communities. Our lessons have been designed to be standards-based, adaptable, searchable, and structured.

While our lessons touch on many standards, we have identified the Common Core Standards that are most central to each investigation.

Lessons are designed as starting points that you can adapt to your particular context. Handouts and resources are included as editable Word documents. Additional resources, pictures, and possible student solutions are included when applicable.

Using the search filters to the left, you can browse our lessons by Common Core Domains, grade bands, and contexts. You can also search for lessons that focus on Philadelphia. 

Lessons have an inquiry focus and follow a common structure designed to engage students in productive struggle with core mathematical ideas. For more on the philosophy behind this structure, view our philosophy page.
