I use Edmodo to post my projects to my students. Edmodo is a safe, social media platform (much like Facebook), but it is only accessible by you, your students, and their parents. There is no other contact to your students, unless you allow that by setting up different groups. The weekly projects are posted each week on Edmodo, so students have a central location for all their instructions, links, etc. They can even access it from home, if they choose to work on their project there.
The first project we did this year was Wordle. Wordle is a word cloud generator. It is very simple to use, so it makes a great first project. Each of my students have their own jump drive. In fact, it was listed on their supply list. Here is the project posting that was on Edmodo:
Be sure and watch this post for examples of the Wordles that my students created. They had a lot of fun making them!
