WE'RE ALIVE!! :) We survived summer AND the beginning of the year!
We have received many emails asking how we planned on transitioning from GLEs (Missouri's grade level expectations) to the Common Core, all while keeping math workshop.
So this is what we did...
We first analyzed the Missouri GLEs to see which Common Core standards aligned.
We then pulled out our yearlong calendar for math workshop from last year:

First, we rearranged the calendar based on last year's experiences. For example, it made more sense to teach mental math strategies for adding and subtracting before teaching 3digit addition and subtraction.
Then we went through and checked off any GLEs that were exactly aligned with Common Core. We tweaked others that were similar but not exactly aligned. For example, a GLE was that students would tell time to the nearest 5 minutes, but now CCSS (Common Core State Standards) requires third graders to tell time to the nearest 1 minute.
The CCSS that were left over and not aligned with GLEs, we stuck those in where they made sense.
We then took out GLEs that were no longer required under CCSS and kept them in mind in case our calendar would permit time to teach them.
Once all CCSS were plugged in, we decided on a few GLEs that we still felt are necessary skills for 3rd graders, so we kept them.
THEN...after all of that, with the weeks of school left, we plugged in the GLEs that are not aligned with CCSS.
Another change that we made to this year's yearlong math calendar was to include the specific CCSS code and/or GLE code beside each skill, so that we could refer back to the exact language of the standard. We also changed the Date column to weeks. This way, we won't have to change the dates each year. Finally, we noted short weeks with a "s/w" so that we would plan accordingly.
Here is a snapshot of what our current calendar is with Common Core:

We are also fortunate that our district adopted the revised Everyday Math Common Core edition this year. We still pull lessons as they relate to the CCSS for third grade. :) EM is aligned to CCSS, but for multiple grade levelssince it is a spiral curriculum.
