Helpful site for interactive activities and accountability

I usually end up spending quite a bit of time looking for activities that I can hold my students accountable for, especially in the sense of literacy and technology. It's especially hard when my core group of literacy kids need a lot of assistance and practice before they begin to understand what it is exactly I am asking of them. I also have one student who needs new activities constantly to challenge him. Then, last week, lo and behold..... I found an AMAZING website! It is www.readwritethink.org and provides loads of resources from Kindergarten-12th grade. This site is for educators and parents! I'm still searching through but I found a great "game" for word families. My students are super excited to start. The best thing is that there is accountability because the students can print out the results of their work. The sheet comes out with their name on it! Try the interactive game!
