Students of all ages often struggle with mathematics concepts, and might even cringe when they hear the word fraction. The purpose of this workbook is to increase conceptual development of fraction concepts and computations through hands-on investigations that contextualize the mathematics. Pattern Blocks(r) are familiar manipulatives in the elementary classroom, frequently used for teaching geometry and measurement content. In this book, students investigate fraction tasks through area or region models with Pattern Blocks(r). The use of area models will help students visualize parts of the whole or region, and can help develop equal share concepts. This workbook includes six sections of investigations that allow students to master concepts of fractions and computations of addition, subtraction, multiplication, and division. Online lessons or materials found in textbooks normally provide only one or two worksheets of problems, which is not enough practice for most students to master the mathematics. This workbook provides a multitude of worksheets for each topic, with a focus on the concrete, pictorial, and abstract levels of learning. A detailed answer key is also provided to help teachers and students assess progress
