I know that whenever I do show and tell, I always say it's my favorite, but this app really is the favorite of all my students. We do Handwriting Without Tears at my school, so this is nice because it has a mode for Handwriting Without Tears. Another thing I love is that it follows the concept of I do it, we do it, you do it. The graphics are great and engaging for the kids so that they want to keep doing it over and over.
When I use Letter School, I generally have the kids learn the prompts and practice on paper or a chalk board first and then follow it up with the app. It's well worth the $5. Check it out at www.letterschool.com.
