There are an abundance of lesson plan websites and many are linked to the Common Core, but if you’re looking for quality lesson plans to help implement the CCSS standards, you’ll want to check out

http://betterlesson.com/. This site has recruited (and PAID) Master Teachers to create Common Core aligned lesson plans for their grade level. The lesson plans are easy to follow and contain downloads of the worksheets, instruction sheets, activities, interactive whiteboard lessons, videos, etc. needed to complete the lesson. The lessons are organized by subject, but if you find a Master Teacher who fits your style, you can see all of his/her lessons at once. You have to create an account to enter the site, but once you do, you can click on Common Core or Master Teachers and browse the lessons. This site is sponsored by NEA (our union dues at work!) and the Gates Foundation so we should expect a quality interface and content.
