How I Use It
I've used this website as a practice tool in my classroom. It's useful because it allows the teacher to set up accounts for his/her students and assign standard-specific practice. Each standard is about 5 questions each and if students struggle with questions there is an option that gives the students "hints". What's even better is that it summarizes the top three common mistakes which is incredibly useful in setting up my future lessons.
I think this is a great tool that makes assigning practice in the classroom easy and quick. It's much better than taking the time to create standards based worksheets ourselves!
