Prodigy Math

Go to the website and try it out. Next, I want you to give your personal evaluation of the app. Does this site seem like it will support what we are learning in class? Is this a site that students should continue to use? Will it help you become a better math student? Why or why not? Be honest with your review but please provide specific evidence that backs up your opinion.
