Learning Language Arts Through Literature My youngest really responded to this curriculum. It gets a bit religious in the higher graders but it can be over looked.
Total Language Plus My oldest really liked this curriuclum but I found it lacking in some of Language Arts Skills needed. Great if your child is reading a specific book, but not so great for a complete Language Arts Curriculum
