NoRedInk is an interactive practice site for grammar.  Rather than multiple choice questions, students are tasked with correcting what is wrong or recognizing that nothing is wrong.  Activities are customized to each students' interests based on a quick questionairre when creating an account. Students receive support via hints and similar problems to solve.  

Take a peek at the video below by clicking the NoRedInk link to see how it works :)
