### The Desmos Guide to Building Great (Digital) Math Activities v2.0

Desmos wants to help every student learn math and love learning math. To accomplish that goal, we build math activities for students, and we build them to the specifications in this document.

Our design code folds in our collective understanding of mathematics, identity, culture, curriculum, cognition, and pedagogy. Together, these ideas can increase the likelihood that a student will come to identify themselves as a “math person.”^{1}

We intend this document to be *descriptive* of choices we have already made and *prescriptive* for choices we will make in the future. When we have doubts about our design decisions, we use this document to settle them. We share these principles publicly in case they’re of use to you and, especially, so you’ll hold us accountable if we fail to meet them.
