If you haven’t already figured it out, I am a fan of the Common Core State Standards. I believe in their potential to increase equitable access to rigorous teaching and learning across the country.

This does not mean that I am opposed to local decision making, in fact much the opposite. I served nine years on a local school board. I recognize the importance of members of local communities speaking out on the design of policies that impact their children. That doesn’t mean, however, that community members in any locale won’t benefit from expertise from across the nation to inform what they offer their children. And that’s why so many state governors collaborated to create a set of guiding standards more than five years ago to benefit our students.

While I support states that believe they need to revisit college and career-ready standards to ensure they capture everything they want for their students, a clear benefit of the Common Core is the power of sharing great lessons and materials across the nation. With aligned standards in place across many states, math teachers in Idaho can network, problem solve, and share resources with math teachers in West Virginia. The best of the best can rise to the top and students will experience engaging lessons every day.

Over the past several years I have seen some remarkable resources developed by, for, and with teachers and thought I would share some of my favorites. Combine these resources with relevant and sustained professional learning and teachers will have the support they need for deep implementation of high standards with fidelity.  The steps that teachers take to collaboratively develop, adapt, practice, observe, and revise lessons based on these resources are among the most valuable professional learning they will experience as they improve their knowledge and skills to reach all students.

I know there is a danger that as soon as I publish my list I will remember others that I should have included. I invite you to add your favorites so together we create a list of great resources to explore this summer.
