What is the difference between the LA worksheets, and the supplemental Language Arts workbooks?

Your Language Arts program comes with everything you need to teach your child to read and write. However, some parents want additional grammar or writing helps. This is why we offer optional Language Arts resources -- like Worldly Wise and Explode the Code -- scheduled in your Instructor's Guide. Add these fantastic resources to help your students gain greater mastery of the English language and writing.
