Google Chrome App Store for Teacher Tools!

I've spent the last hour on Google - https://chrome.google.com/webstore - finding amazing free apps for teachers! Go to the Chrome Web Store, scroll down through the apps to Education, CLICK and then CLICK on Teacher & Admin Tools.   It's like Christmas for teachers! These are some of the apps I got: 

I already use Class Dojo and it's awesome!!! If you haven't tried it, it's a class behavior management program that doesn't cost the teacher ANYTHING!!! NO SURPRISE BOXES and SURPRISES that take your grocery money!It also lets you communicate daily with parents and shows them how their child behaved that day. WONDERFUL!!! NO NOTES TO WRITE HOME!!!!!
