So I had a chance to check out the Fourth Grade Common Core Workbook that I found out about yesterday when they sent it to through the giveaway. It is GREAT! It has the feel of a bunch of well done TpT lessons bundled in one collection. It is all organized by standard. In the English section there are mini posters, activities, organizers, and passages for each of the standards. They even used adorable clipart. I'm telling you this is good stuff. For the math it also has just what you need. It would definitely be worth the asking price but if you are fourth grade blogger I would absolutely participate in the giveaway before it expires on Sunday.
