Here is an excellent source created by the University of California Museum of Paleontology, “Understanding Evolution for Teachers“. The site for teachers is part of a larger site for evolution.
The section for teachers is divided into learning about evolution and teaching it.
Topics include the history, understanding of evolution, including misconceptions and relevance to our daily lives. The site is geared toward teachers with lesson plans, but there’s also a section that’s geared toward all readers, not just those who are teaching.
This is a very thorough website, neatly laid out with information and hands on lesson plans for teaching specific concepts. A very helpful feature is their search options. You can search according to grade levels, K-2, 3-5, 6-8 and 9-12, by topic or keywords.
To see everything laid out, their site index is neatly laid out and very easy to follow. They, also, have a very nice glossary with short concise definitions and pronunciation guide for most of the terms.
Web pages, also, have graphics to illustrate the points made in text. And while there’s a lot of information on the website, there isn’t a preponderance of text on individual pages, making it easy to read. Links lead the reader to other sections of the website for further study or clarification and/or to outside resources.
This is a great resource for both understanding and teaching evolution. It can be used exclusively or nicely supplemented with living books. While it’s not specifically for homeschoolers, the lesson plans I looked over can be easily adapted for use in the home.
