The teacher can teach the grammar lessons and then use the grammar slammer mini-lessons as a review. Grammar Slammers can be used 5-10 minutes daily to keep the students abreast of grammar skills needed for writing and speaking properly.
I passed out the Weekly Worksheets on Mondays and assigned a few sections for the students to work on. Afterwards we would check over their answers. Tuesday-Thursday, the same thing and then on Fridays I would give them a little assessment. The students kept the worksheets in a folder so that they could get it out every day.
If you teach grammar only once a week, then you can use the grammar slammers as a review or as a quiz.
