Every week I send home papers completed in class. I include any flyers from the office and a coversheet that parents need to sign. Biweekly I send home grades, although parents can keep updated if they have an account to the school website. I use powerpoint to make the coversheet, so it's easy to change the information.
Also I've made a class for ScootPad. Is there anyone out there using this website? It's free which is one of the reason I joined.
