I used this for RTI this year. It worked really well. The students have to re-type the problem/sentence. They can't just pick A or B. I had kids realize they weren't putting the comma in the correct place. That is has to be in the exact location.
I think the students enjoyed not reading a passage and answering questions for a change. This is just grammar ---but there is a lot to choose from.
How I Use It
I used it for remediation.. I found the lessons/skills I wanted them to work on. These students needed just some basics to help their writing.
