The Factor Tree is a great site that I just found by being a Bzz agent. I was given a FREE trial and allowed to create parent tools and kid worksheets for counting and learning math! I love how the site is organized well, has an option for a kids login, and offers a progress area. I think this tool is great because it meets parents and kids needs.
I hope you will checkout this site I found! For YOUR free trial, checkout my post on Facebook!
