Additive Inverse Teacher Resources

Teach your class about the additive inverse! Using examples first and a definition second, this video explains what the additive inverse it and how to find the additive inverse of any given number or variable. A quick concept review for...

Finding the additive inverse is not as complicated as you might think. The instructor demonstrates how to multiply each of the terms in the polynomial by -1 and explains how this works. But wait, there's a quicker way. What's that you...

This resource would actually be best used as a projection when teaching about additive inverses. The first "page" shows on a number line how 6 and -6 get you to zero. The second supplies an opportunity for viewers to apply the concept to...

Simple tasks are presented for your seventh grade math masters. They are to determine whether two numbers on a number line are equidistant from zero and what the two added together would be.

Additive inverse, expression, and irrational numbers are a few terms you'll find when you use a set of 22 flashcards designed to reinforce math vocabulary. The set includes two types of cards; a bold-faced word card, and a corresponding...

Middle schoolers investigate properties of additive inverses.  In this properties of additive inverses instructional activity, students discuss the what it means for two numbers to be opposites.  Middle schoolers discuss representing...

A good complement to any integers unit contains a three-day lesson plan about positive and negative integers, adding and subtracting integers, and how to find the additive inverse. Additionally, it provides all necessary worksheets and...

In this additive inverse worksheet, students solve 8 short answer problems. Students identify the additive inverse of a given integer such as negative thirty four or positive twenty five.

The instructor demonstrates that when you add the opposite value of a given number to that number you will always get zero. Then she shows how multiplying by the inverse of any number except zero will equal 1.

Middle schoolers use inverse operations to solve two-step equations. They study a story problem about inverse operations, watch a video about the problem, and complete a handout for the inverse problem. Pupils finish with two assessments...

In this properties of real numbers worksheet, 9th graders solve and complete 14 different problems that include identifying and applying various properties of real numbers. First, they name the property illustrated by each given...

In this polynomials worksheet, 9th graders solve and complete 12 different problems that include adding and subtracting. First, they identify and combine like terms. Then, students find each sum or difference using the appropriate...

Middle schoolers use discs in order to add and subtract integers. There are manipulatives present so kinesthetic learners can access the curriculum. They also review the concept of the opposite of positive and negative numbers.

Young mathematicians solve and complete 22 different problems that include using a number line to evaluate. First, they define each of the terms listed. Then, pupils graph each integer on the given number line. They also evaluate each...

Pupils complete activities to learn notation and uses for positive and negative numbers. In this number system lesson, learners play a game similar to Jeopardy to learn how to solve problems with positive and negative numbers.

This resource will knock your "sox" off! It comes with so many worksheets, projects, and other attachments that help you prepare your mathematicians to see positive and negative integers in the real world, including the White Sox stadium...

Sixth graders add and subtract positive and negative integers. In this integers math lesson plan, 6th graders review the number line as a class, with students representing the numbers and moving in a positive or negative direction to...
