What it is: The progression videos are a series of videos that show how math concepts build and grow through the grade levels. 

How to use it: Engaging for teachers and easy to understand, the videos help teachers clearly see what students need to know and do, how it builds on their existing knowledge and skills (coherence), and how it prepares them for what comes next.

What it is: Shows different strategies within each progression along with common misconceptions and what to do when misconceptions occur. 

How to use it: This is a great resource to use when teachers are looking at student work and can give them ideas on how to support students.

What it is: An in-depth narrative describing the progression of a topic across grade-levels.

How to use it: Ideal for those creating math guidance or professional development to deepen their own understanding of progressions. Due to its depth, I typically share it only with interested teachers or district math leaders, and it can be used selectively rather than read in full.
