There are so many great resources out there! The one I want to share is betterlesson.com. This site is filled with common core aligned lesson plans. There are three categories: ELA, math, and next gen science. After choosing which category you are looking for, it provides subcategories for each subject, then takes you to the particular standard. All of the lessons are free and most integrate arts in some form!
