I usually talk about using technology with kindergarten students, but I also work a lot with the first-third grade teachers in my building with how to integrate technology into their curriculum.
While on one of my favorite sites (www.havefunteaching.com) recently I came across a FABULOUS resource for second grade teachers!!!!!! The Second Grade Common Core Workbook is full of worksheets, activities, posters--all the stuff you need to address the Common Core Standards. You can download a sample to check the quality--I did that for the kindergarten book--very impressed! It is a digital download, so you won't have to lug around another big, fat TE! Check it out :)
