Here is an awesome video to get you excited about Google Classroom!
Google classroom is an amazing app that you already have access to! Through the Google Classroom, you are able to communicate with your students and post assignments for them to complete. Projects that students create in other apps (Thinglink, iMovie, Popplet, Educreations, etc.) can easily be uploaded to the Google Classroom for you to view and assess! You can even return student work if you would like editing done, then students can re-submit when ready. It makes grading student iPad work SOOO much easier!
Basic information about the Google Drive can be seen in this short video!
Think of the Google Drive as a digital file cabinet! Except ... it's way cooler than a file cabinet. In the Google Drive, you can upload Docs and PDFs that you already have saved on your computer. It is a "cloud" storage for you. In addition to uploading things, you can also create Documents (Google Docs), Presentations (Google Slides), Spreadsheets (Google Sheets), and Google Forms (check out my example below) directly in the Drive.
In my teaching experience, one of the greatest features of Google Drive, is that you can share documents with your colleagues with the click of a mouse. No more making a photocopies for your grade level team! You can just share the document in the Drive and they have access to it. Or better yet, you can share a grade level folder, and your colleagues can browse your "file cabinet" at their leisure.
Google Classroom and Google Drive go hand in hand (as well as docs, slides, and sheets). If this is something you would like more information about, please complete this Google Form!
