We are discontinuing the sale of these books as of December 2016. Individual tasks remain available for free download in pdf form from our website.
In each booklet you will find a collection of mathematical tasks. Each task has:
A problem statement;
A collection of Common Core State Standards to which the task applies;
A commentary discussing the pedagogical and mathematical concepts pertinent to the task;
One or more solutions for the problem at hand.
The tasks were created to clarify the meaning of the Standards for a variety of stakeholders, particularly for teachers and teacher leaders. We hope that they are useful to spark discussions and enable collegial conversations. They can serve as a starting place for professional development activities.
