We've got the entire series for our children and LOVE them! I'm planning to use them as curriculum in our homeschool with the workbook PDFs you can also get from their website, but my kids keep stealing them off the shelf to read on their own! I'm so glad these books are out there to help my husband and I teach what used to be taught but has now been twisted by mainstream education. If you haven't already, read the Tuttle Twins book, Education Vacation, for WHY these books are so needed!!!
