I have been using the free thinkwave gradebook for a long time now.  https://www.thinkwave.com/secure/login/?next=/free/gradebook/.  It is great for keeping up with grades, report cards, and transcripts.  However, most of my lesson plans for the week ended up scribbled on a piece of paper.  I found a new website that I think I am going to love.  It is very user friendly and allows you to set it up to fit your needs.  The older Kyler gets the more I think that I will love this.  However, it is set up in a way that lets you keep it simple for younger students like my 4 year old, Kellen, who is still in pre-k.  http://www.commoncurriculum.com/ .  I have seen other sites that offer free lesson plan organization, but I just didn’t find them as user friendly.  I don’t want to spend more time figuring out a site than I do planning their lessons.
