I love that there is a diagnostic so the practice is individualized, and the students can move at their own pace. The only part that is frustrating is on some when they have to combine sentences, it will say they are incorrect even when it is correct. But that is minor issue compared to the practice they are getting. Best of all, the free version is great!
How I Use It
I have my students take the diagnostic at the beginning of the year. Then we have independent practice on the strands assigned to them. We use it twice a week for 10 minutes each time.
