I would not consider facebook an effective tool for education. In the news, too many teachers are getting themselves in hot water over things they post on facebook. Also, several states are considering adopting laws where it would be illegal for teachers to have students as "freiends" on facebook. If you are looking to use a networking site for communication for schools, I would recommend edmodo.com instead as it was designed as a platform for schools/districts instead of for social purposes.
I use the Common Core App on my tablet and through edmodo. It is organized in a way that makes it easy to find the CCSS that you are looking for with the click of a few buttons.
I use the app in help with lesson planning and transitioning from Illinois Standards to CCSS.
This can't really be customized for the classroom, but you can choose a grade level.
I would recommend this app for people lesson planning away from their classroom.
I use this site a s "cental hub" for my classroom. All things we do on the computers can be centered around edmodo. Edmodo is the most valuable resource that I have found for my classroom. Edmodo is helping me use 21st century skills in my classroom. Teachers can create quizzes (that you don't have to grade), polls, and assignments that can be turned in without the use of paper. It also has tons of teacher communities where you can collaborate with teachers around the world who are teaching the same thing you are. You can also collaborate with classrooms. The list of applications on edmodo is almost endless and they are currently working on several new features. This site is amazing, and it is made even better by the fact that it is free! I would recommend every teacher k-college to use edmodo in their classroom. It is amazing!
Classdojo just created student log-ins where students create an account and are given a secret code. The secret code allows them to be synced to a classroom to view their weekly points and design their own avatar.
I use this tool in a jr. high classroom. Before I introduced the program, I feared that the monsters would be too childish for this level students, but they responded amazingly. They love the monsters, and I have even set up a competition between my 3 classes to get the highest positive percentage. It is very customizible and even comes with options to use a smartphone or tablet as a remote. I just have the homepage projecting. When students are working, I give negative and positive points for specific reasons, and it encourages students to work hard. There is a negative and positive sound and it pops up on the screen. This is real time encouragement. You can also go back and leave a comment about why a specific student earned a positive or negative. This is really good for documentation and proof of behavior problems. I have already recommended this program to my colleagues and I am actually doing a summer training session involving using ClassDojo for behavior management.
