Workbooks and Textbooks
Writing With Ease, aimed at first through fourth grade or an older struggling student, appeals to classical educators. The Instructor Textbook contains 144 lessons costing about $30. Diagnostic tests determine where students should start. The Student Book is available in print or as a PDF download for about $25 to $30, and the Student Pages, also available as a PDF, cost about $12.
If you want to blend the two subjects, try Beautiful Feet study guides. They combine literature with subjects as diverse as history, science and geography for all ages. Their study guides, which cost about $10 to $15 dollars, contain reading, research or response assignments. Some of the guides are available in PDF format. They sell literature packs that contain all the books with a given study guide, but check your library first to see if you already have the required literature.
Study guides for individual books containing lesson suggestions are available from Progeny Press for under $20. For fifth through seventh grades, the series Write Your Own publishes inexpensive workbooks targeting specific types of writing including tall tales, newspaper articles, poetry or fiction. These 64 page books are priced under $10.
