How I Use It
I use this to help create teaching tools for me to use with students. It has numerous student driven lessons but my students seem to find them to be boring after continued use. I also use the lessons to send to students who are absent from class. The tutorials help them to understand missed content.
This is a great tool to pull stuff from. It does have activities for students that are meant to be able to stand on their own but I don't believe they are engaging enough. The nice thing about using them though is it allowed differentiation to easily take place in the classroom.
