I’ve chosen these for our early readers or those that are not reading yet, but enjoy mommy or daddy reading aloud to them. The books are full of natural science focusing mostly on life science. They are written in a friendly narrative style your child is sure to enjoy. These are also a great alternative for those that are reluctant, not ready for textbook layout, or for those using the Thomas Jefferson Education methods. They are categorized by a broad range below. Most of these have an option to print. There are many more on Google Books. You can use some of the words in these titles as key words in your search. You can read more about searching for free ebooks on Finding Free Textbooks on Google Books or Searching the Internet Archive.
We like these books because they are so charming and they are full of wonderful vocabulary. My oldest has been working on writing her own book about butterflies for weeks now. She studies in science units and on other websites about various topics of interest for her book and then adds detail to her butterfly narrative. I have been patiently awaiting my turn to edit and revise.
