Microsoft Word, Excel, Power Point, and Dropbox have all been good, but why stick with good when there is better? Google Drive allows you to keep everything you create in one place and easily share it with others. Not only can you share your files, you can collaborate together on projects in Google Docs, Google Sheets, Google Slides, or Google Forms to name a few. I can work in peace and quite at home on a project while my coworkers or classmates add to the same project at a loud coffee shop. We can both view each other's live edits without physically being at the same place.
Another benefit of Google Drive is that you can access your work anywhere at anytime. You are not tied down to one device that may crash and burn and loose all your hard work. I can work on a project at home, save it to my Google Drive and then access it later on my phone or at work. In regards to saving a project, I never have to worry about forgetting to press save. All changes are automatically saved. If I want to revert to a previous version or take note of what a collaborator added, I can view revision history.
Google Drive contains many wonderful apps. The most popular are Google Docs, Google Sheets and Google Slides. You can search for more apps to add to your Google Drive in the Chrome Web Store or by selecting to "Connect more apps" under the "New" button in Google Drive.
Most recently I have been experimenting with Google Forms. Within Google Forms I can create a survey or quiz for my students. Check out this quiz my students are going to take this week over area models for multiplying and determining the number of terms in an expression.
There are so many wonderful features and apps in Google Drive. Go for a test ride and let Google Drive. If you wish to download Google Drive to any of your devices, visit Google Drive's website.
