This special font was created especially for an elementary teacher, Rachelle Smith. Rachelle's highly-popular teaching blog, What the Teacher Wants (http://whattheteacherwants.blogspot.com/) is a great resource for elementary teachers. She also sells educational products at Teachers Pay Teachers: http://www.teacherspayteachers.com/Store/Rachelle-Smith
This font is exactly "What the Teacher Wants"- it is neat, legible, friendly, and contains enough glyphs to cover 86 languages and little extras like math symbols!
As always, please pay for commercial use. Thanks!
