Visual and manipulative models such as fraction circles and fraction rectangles are ideally suited to the exploration of fraction concepts. With the activities in this book, students build on their earlier explorations of fraction ordering and equivalence by comparing fractions with different numerators and/or denominators, decomposing fractions, adding and subtracting fractions and mixed numbers with like denominators, and multiplying a fraction by a whole number. Each lesson includes connections to current math standards, teacher notes and instructions, practice worksheets, and assessment pages. This book is an ideal resource for students who need instruction in or review of the fourth-grade fraction standards.
