This book is based on the lyrics of Dr. Jean's "Numeral Song". My students love Dr. Jean! We use her songs and videos a lot in my kindergarten classroom. I created this resource for students who are learning how to write numerals. To learn more about Dr. Jean check out her website drjean.org . There are many wonderful resources there. I recommend purchasing her CD- "Sing to Learn" which includes this song along with many other educational tunes!
