If you're looking for a special way to teach the Psalms to little ones, you may want to check out the book How I Praise You! 150 Little Psalms in Song. Author Donna Moss wrote me recently to share information on this book, as well as her website which offers 29 ways to use the book with children and great links to Psalm related websites.  Although I haven't personally reviewed this book, it seems like a great resource for anyone looking to teach the Psalms and share a love for music with little learners.
