From a fellow Tech Mentor: It's a great resource for creating tests, quizzes, and worksheets. I really like that you can save it as a google doc. It will import it directly into your account (provided you've allowed it to do so). I used it on the iPad and it went straight to my google drive app with no problems. This would be great for teachers to upload it directly to their sites, have students collaborate with it on iPads, etc. I love it, only drawback for me, it's for 4-8th grade (insert a few tears)! I'll definitely be forwarding this on to our teachers.
Create a QR code that will direct students or parents to a specific website or e-mail. You can place the QR code generated on worksheets, signs, posters.
This website has some games on it but what I really like is the seating chart, group generator, and random name generator. I used it for student teaching and it is easy to upload a class list (make sure to just use their last initial for safety purposes).
