Just as they begin to run short on cookies, Grandma arrives with a huge platter of new cookies, and new problems to solve.Go to: How to Use This BookHighlights and InsightsRelated ORC ResourcesOhio Standards

 How to Use This Book Kindergarten or first grade: The class could role-play a tea party event. As the book is ending, Grandma shows up with more cookies, providing opportunities for extension activities for the upper elementary grades. At the very end of the book, the doorbell rings one last time without revealing who is there, providing multiple opportunities for further extension: What if more people show up? What if more/different cookies show up? Students can suggest additional extensions.
 Highlights and Insights This book could be used to teach multiple concepts in the number, number sense, and operations standard, and therefore can span grades 1 - 4. Students can discuss what they might do if 5, 7, or 8 friends showed up, perhaps opening a discussion of fractions.
