This link shows simple ways to incorporate social media in the classroom. It helps parents and students stay involved even at home and it also reminds students that what they do online is being monitored and could be used against them in the future.
I think this is a wonderful idea to remind kids of all of the different qualities they possess and can share with their classmates. It also lends students to understand the variety of interests and talents of their peers as well.
While this post is for first grade, it would work GREAT for multiplication and division facts for grades! The video on the post tells you exactly what to do. GREAT for a center, or to use as a whole class activity when you are out and have a sub.
