Book excerpt: On My Way to Grandma's House is one volume in a series of educational guides published by Math4Minors, an educational service organization designed to help teachers, Command and Conquer the Math Curriculum. By integrating a simple story with a detailed learning strategy, this series helps build strong foundational skills and a deeper understanding of the math concepts that are embedded in common core and state standards. At first glance, this story about Lily and her friends seems to focus primarily on the concept of rounding numbers, a standard identified in the Number and Base Ten standards found in grades 3, 4 and 5. However, rather than looking at rounding as an isolated skill, Math MileMarkers uses this opportunity to encourage teachers and children to explore the number line in places they may never have been before. Don't underestimate this simple story, its message reaches far beyond Lily's trip to grandma's and another happy ending.
