Family of Problems is dedicated to building a warehouse of creative, interactive, flexible problems for innovative math teachers. All the problems within this site have been successfully used by experienced math teachers in the classroom. These problems are also vertically articulated by grades. For example, each task is presented with a task for primary and upper grade concepts. This allows teachers to use the problems across grade levels to unpack the learning progression. (see VAULT problems- Vertically Articulation to Unpack the Learning Trajectories) Problems are grouped in threes based upon related content and learning concepts. Each problem is documented with a front door, lesson plan, and black line master; and links to its two closely related problems. The problems are listed below organized by grade level, big idea, and alphabetic order. Enjoy!
