“Do you realize that Muffins spelled backwards is Sniffum?”
 
1-15 January 2004, The Booklist (Chicago, IL), “What Is It? Musical Math & Science” by Paul Shackman, pg. 896:
What Is It? Musical Math & Science. 2003 57min. Re-Bop. CD, $14.98. 800-657-3267.
 
PreS-Gr. 2. The core concept of this CD is that picture books are useful jumping-off points to explore basic science and math skills in an easy, entertaining way. For example, Rosemary Wells’ Bunny Cakes (2000) serves as the inspiration for “Muffins Spelled Backwards,” a tune about combining and measuring ingredients, while title song “What Is It?” is based on Ed Young’s Seven Blind Mice (1992)
