Essentials in Writing provides well-organized grammar and composition instruction for grades 1-12 that is easy for the teacher to implement. Lessons are taught via video instruction by experienced teacher Matthew Stephens. Videos are fairly short, ranging from 3-4 minutes in earlier grades to 7-8 minutes in upper grades. Worksheets coordinate with the video lessons and cover from one to several days depending on the lesson. Checklists and guides help the teacher to assess student work, and an optional assessment book is available for some levels. The videos are available in DVD format or through an online 12-month subscription.
