Real Life Math Investigations

Book excerpt: Each investigation in this book asks a question and presents a plan of action. None has a single 'right answer, ' yet all can be answered in some way. There's no answer key--it's up to students to use their critical thinking skills and number sense to evaluate their work and the work of their classmates. It's up to you to help them recognize and apply the math ideas embedded in every investigation, such as patterns and relationships, computation, estimation, measurement, statistics, and proportional reasoning.- from the book.Grades 5-8.
