However one of my favorite sources is A Journey through learning this is an excellent source for lap-books. Their Apologia lap-books for the Elementary Series are currently on sale for $8.00! I purchased all of these a couple of weeks ago. We are working through the Land Animals book.
Boo has commented a lot that she thinks the lap-books are helping her remember the work.
This is a photo of Boo with the lap-book she made about Primates. This came from the Apologia lap-book for Land Animals of Sixth Day.
