This book contains a collection of multiplication lessons that support curriculum and instruction. The goals of the lessons are to give all students the chance to learn how to mentally multiply by 10, powers of 10, and multiples of 10; use the distributive property to calculate products; use paper and pencil to record thinking when solving problems involving multi-digit multiplication; identify factors, multiples, products, primes, and compositions; and explain how multiplication relates to addition and division. In order to help teachers with planning and teaching the lessons, each lesson is organized into sections that include an overview, materials, time, teaching directions, teaching notes, a vignette describing the actual lesson, follow-up suggestions, and questions and discussion.
