This workbook has 850 pages of worksheets, activity centers, and posters that teach the Common Core ELA and Mathematics Standards. What an easy and great way to add more resources to our "arsenal" as we all adjust to the Common Core Standards.
The workbook retails for $39, but they are currently running a contest to earn a free one until April 21st. You can enter the contest here. I am looking forward to getting a free copy of my own and implementing some activities before the year is over!
