Solving word problems is a critical skill that all students need to master. Drawing is a highly effectively way for students to model and solve problems and to show their mathematical thinking at the same time. Each of these 40 classroom-tested worksheets features a word problem along with plenty of space for students to draw the problem and work through their solution. Students should model the problems with simple, age-appropriate drawings. Aligned to the standards, the book is organized by the 13 types of addition, subtraction, and multiplication problems second-grade students are expected to be able to solve: Addition: Add To/Result Unknown, Put Together/Total Unknown; Take From/Start Unknown, Compare/Bigger Unknown; Subtraction: Take From/Result Unknown, Take Apart/Addend Unknown, Take From/Change Unknown, Add To/Change Unknown, Add To/Start Unknown, Compare/Difference Unknown, Compare/Smaller Unknown; Multiplication: Equal Groups/Unknown Product, Arrays/Unknown Product.

With a hundred board and the thoroughly engaging activities in this book, students in kindergarten through second grade can explore counting and ordering numbers, place value, number patterns, beginning addition and subtraction, and more. A first-of-its-kind teacher resource, the Hundred Board Book features 60 activities and games with accompanying teacher notes, as well as links to the Common Core Standards. Includes a CD for IWB presentation and hours of interactive fun.

In this introduction to algebraic concepts, middle school students explore the idea of algebra as a balancing act using dice and colored tiles. When given the opportunity to play with big mathematical ideas, students naturally acquire the algebra basics: using symbols to denote mathematical functions; using a variable to represent an unknown; and writing and solving simultaneous equations. These highly engaging team activities generate friendly competition, and provide a reason to learn and use algebraic concepts. These dice and tile activities address the CCSS of Number and Operations and Algebra as well as the Mathematical Practices of reasoning and problem solving. Includes a CD with a digital edition of the book as well as a dice roller for use with your interactive whiteboard or computer to make the activities fun for the whole class. 136 pages.

Help children develop coordination and fine motor skills with this series of two books created by occupational therapists and classroom teachers. Each book outlines developmental milestones for children aged 4 to 7 that can be used for planning, assessment, and creating individual education plans. Reproducible worksheets provide multiple opportunities for children to practice cutting skills in an engaging format. Worksheets are accompanied by teacher notes with simple, easy-to-follow instructions and information about hand dominance, scissor grip, cutting line accuracy, body posture, and thumb position when cutting. In this book, children learn how to cut along corners and curves. In the companion book, Developing Cutting Skills (Stage 1-3), children learn how to hold scissors and paper and cut along a straight line.

Many elementary and even advanced mathematics concepts can be modeled nicely with two-color counters. This activity guide for grades 5-8 provides teachers with proven techniques to help their students better understand abstract mathematical concepts. Students use the counters to explore fractions, positive and negative numbers, equations, data analysis and probability concepts, and mathematical problems involving patterns and deductive reasoning. Accompanying CD includes digital version of book and virtual counters for whiteboard presentation.

Students in grades 8 through 10 will get all the mental math practice they need with the fast-paced, engaging exercises in this series. Each workbook provides a structured daily program of practice and consolidation for an entire year. Students answer 20 questions per day, many within the context of real-world situations. Each grade-level workbook supports basal math programs and key concepts needed for success on standardized tests. Separate teacher guide provides suggestions for implementing the daily mental math program, assessment ideas, formulas to know, answer key, and more.

The hundred board can be a versatile tool for mathematics learning beyond the early grades. Using the 60 engaging games and activities in this book, students in grades 3 and 4 construct and extend number patterns and reinforce place value learning. They also develop an understanding of multiplication and division by making the necessary connections to addition and subtraction. As students become familiar with factors and multiples, they develop fluency with efficient procedures for multiplying and dividing whole numbers. They also develop the problem-solving abilities outlined in the Mathematical Practice standards of the Common Core. Includes teacher notes, links to the Common Core Standards for grades 3 and 4, and an interactive CD for IWB presentation.

Tangrams help students comprehend basic geometric ideas while supporting number sense development in engaging, mathematically rich situations. As students work through the 60 engaging activities in this book, they describe their physical world using geometric ideas, visualize spatial relationships, and reason with shapes and their attributes. They explain their solutions and justify their conclusions while using manipulatives to support their reasoning. Each lesson includes teacher notes, blackline master, and links to current mathematical content and practice standards.

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.

The hundred board is not just for the primary grades. It's a versatile tool for mathematical learning into middle school. With these 60 activities, students construct and extend number patterns, use place value, find common factors and multiples, work with prime and composite nunbers, and much more. Each activity is correlated to current mathematical standards. Interactive CD is included for whiteboard presentation.
