Newly revised and updated for the current Math Standards, this popular title is a complete resource for helping students to visualize the algebraic process. Students model math problems with algebra tiles to build and solve equations while gaining comfort and skill with algebraic expressions. Teacher's notes and reproducible activities cover integer operations, linear and quadratic expressions, perimeter, arrays, binomials and more. Each topic progresses through: objective, prerequisites, getting started and closing the activity.

The engaging activities and games in this book use the 100-bead Rekenrek to extend students understanding of counting, place value, the four operations, and algebraic thinking. Students will make groups of tens and ones, add and subtract within 100, explore multiplication, and more. Each of the 24 lessons is correlated to current standards and includes instructions, assessment questions, and blackline masters.

The Rekenrek has emerged as an ideal tool to provide students with a strong understanding of early number concepts. Using the Rekenrek, the 48 engaging activities in this book help children master early skills such as counting, subitizing, decomposition of numbers, and more. Each lesson is correlated to current mathematical standards and includes step-by-step instructions, suggested assessment questions, and blackline masters. Grades K-1.

Sharpen your students' higher-level math skills with these fun dice games and activities! These classroom-tested activities immerse students in developing fluency with the concepts of square numbers, square root, primes, factorials, summations, and positive and negative integers. Tied to the NCTM standards, these engaging games and activities provide practice without paper-and-pencil drill. Includes notes, instructions, and reproducible charts and game mats for over 75 activities, as well as independent explorations. Grades 5-8.

Students can do so much with the beaded number line: counting, skip-counting, place value, rounding to the nearest 10 or 100, operations on whole numbers and decimals, and more! Developed by respected math educators, this reproducible resource provides 60 classroom-tested activities divided by grade level. Activities are designed to help students visualize quantities and number relationships in a concrete way before they transition to the open number line and abstract strategies. Each activity focuses on a specific standard and includes instructions, assessment questions, and blackline masters. Formative assessments are provided for each grade level.

Suitable for use in grades 3-6, this reproducible activity book is designed to supplement any core mathematics program. Students will enjoy learning multiplication facts 2-10 as they pair up to compete in challenging dice games such as Four in a Row, Square Off, and Cross Over. Created and tested by veteran math teachers, the book is founded on classroom research and practice that shows children learn most effectively through play. Activites address the NCTM content standards of Number and Operations and Probability while also addressing the process standards of Reasoning and Problem Solving.

Using the 12 pentomino shapes and the lessons in this book, students will explore measurement (unit, area, perimeter), number (multiples, triangular numbers), geometry (congruence, similarity), and much more. Activities range from simple explorations to highly challenging puzzles. Pentomino play enhances students' intuition, problem-solving skills, strategic thinking, and spatial sense. Includes a CD with a digital edition of the book and virtual pentominoes to make the activities fun for the whole class. Also includes detailed teacher notes, answer key, and correlation to Common Core Standards.

Get your students ready for fractions and pre-algebra concepts with this engaging division resource. Students will actually want to practice division with these 20 different games for developing fluency with divisors, dividends, quotients, and remainders. Ideas to differentiate activities provide extra fun and challenge for students who are ready for it. Includes a CD with interactive dice and a digital version of the entire book for computer and whiteboard use.

This updated edition of Nimble with Numbers correlates lively and challenging activities to key instructional standards and now includes a CD for whole-class presentation. Nimble's winning format remains the same: meaningful practice of high-priority skills through games, computational mini-assessments, and independent activities to maximize number and operations learning. Topics covered in this series include facts and operations, place value, multiplication and division, fractions and decimals, and money.

The geoboard has a wide range of uses in the study of geometry, from constructing very simple shapes to making many advanced geometric and algebraic concepts easier to understand. Using Working with the Geoboard as their handbook, teachers are sure to get the most out of this versatile tool for math understanding. Armed with a 25-pin geoboard and the activities in this book, students calculate area and perimeter; explore the properties of quadrilaterals, triangles, and other polygons; discover formulas; and work with number patterns, the coordinate plane, and rotations and symmetry. When it's time to investigate circle geometry, students simply turn their geoboards over and work with the circular pin array on the reverse side. CD for IWB presentation included.
