WordBuillder Intervention is great!

I have just started using WordBuilder with my struggling readers and they love it. I enjoy working with students in the WordBuilder application, directing them to break down words and then build them back up again. The reward games are simple but fun and I appreciate that students have to earn enough coins to be able to play.
