When I was teaching in the elementary grades my students would spend some time each morning editing sentences and then we would discuss the corrections together (Daily Oral Language).  I think that if I were teaching Language Arts today, I would replace that activity with having students use Grammar Bytes.  It offers teachers and students a glossary of language terms, worksheets, presentations, and (my favorite thing) interactive exercises.  Each interactive activity comes with a handout where students can record their scores and measure their progress.  I could have students view the presentations at home on their own and then have them do the activities in class where I can support them (flipped classroom.)
