I had a few parents ask about what sites need logins and which ones are free. I am not sure if they are all apps, but I know most of them are and most of them are free. Xtramath is a paid app and I have found the website is much more user friendly! I put an * next to the links that the kiddos will need a school password for. I will email letting you know when those have gone home so you know when to look for it!The rest they should be able to get on and use when you are ready for them to!
