This book is special because the idea came from Ms. Marquez’s daughter and her friend when they were just in second grade. The two girls stapled together pages and began the silly story of where some of the math symbols came from. As a math specialist Ms. Marquez couldn’t let this story go unshared, so she added more about the other symbols and here we have it; a silly story of where the math symbols came from!
