As promised, here's another method for resource-strapped districts to access model curriculum units.
There's a huge opportunity for sharing resources among districts. In the Pioneer Valley, many districts are already creating high-quality, Common Core-aligned products. Frontier Regional Schools are backwards-designing curriculum units, the Ludlow Public Schools math department is building a curriculum map that embeds the Standards for Math Practice, and at Tantasqua Regional they've aligned report cards to the new standards.
You might ask, how will we access those materials? One way is to join our Curriculum PLC when it meets to share Common Core implementation resources and strategies on May 31, 8:30 to 10:30, at CES, 97 Hawley St., Northampton, Massachusetts. Contact me if it'd be easier to skype in. Another is to follow this blog!
