To help students succeed in learning math at school or at home, Summit Math books start with simple, foundational concepts and build on those ideas in small steps. Written by a math teacher with 16+ years of classroom experience, this series is designed to help students learn at different paces. Each book is split into 2 parts: 1) Guided Discovery Scenarios, and 2) Homework and Extra Practice Scenarios. The Guided Discovery Scenarios gradually develop new concepts, building on previously learned topics. The Homework and Extra Practice Scenarios improve your understanding and increase your ability to retain what you have learned. Each part has a separate Answer Key, which is included to promote learning. When you finish each scenario, you can check the Answer Key to see if you are ready to move on or if you need more guidance. Book 4 Contents: Introduction to polynomialsMonomials, binomials, and trinomialsAdding polynomialsSubtracting polynomialsMultiplying polynomials: part 1Writing polynomials in standard formMultiplying polynomials: part 2Multiplying binomials to form another binomialSquaring a binomial to make a perfect square trinomialPolynomial scenariosCumulative ReviewAnswer KeyBook description: In this book, students learn about polynomial expressions and then they use what they have learned about operations with numbers to discover how to add and subtract polynomials. Students use what they have already learned about the distributive property to discover how to multiply binomial and trinomial expressions. They also investigate special cases that occur when multiplying binomials. They explore cases where the product of two binomials is a binomial and they look for patterns that occur when a binomial is multiplied by itself. This book prepares students to learn about factoring in Algebra 1: Book 5.
