I use ClassDojo as a communication app for the classroom. It is also available through a website. I sent home information, so parents may sign-up. It connects teachers, parents, and students so I may share photos, videos, and messages through the school day. I use ClassDojo to work together as a team with parents and students to share in the classroom experience.
I also send home book bags with my reading students. In the book bag is a book at your child´s level that they chose to bring home to read. There is also a book log for parents to fill out each night.
