Thanks to Kathy from the Yahoo! group KindergartenD5 for sharing the link to this valuable font. It is called ABC Print Arrow.
The following link has dotted lines for practice, too.
Here's a link to some others you might like if you are teaching D'Nealian and need a free comparable font.
Heart fonts for Valentine's Day
Dr. Seuss Font
Smiley Monster (One of my favorites!)
I'm still a huge fan of the Tinker Toy font.
The following links have lots of fun fonts for scrapbooking, but they are also very cute for games, printables, bulletin boards, etc.
If you have some favorite fonts you'd like to share, I'd love to hear about them.
