Additive Inverse Teacher Resources

The resource consists of a discussion between a mentor and two students about how to use additive and multiplicative identity and inverse properties. Examples and explanations of each are included.

Test your knowledge of the number properties. This challenging practice really puts you to the test. Assessment covers all number theory properties: associative, commutative, distributive, inverse, and identity.

Students explore the inverse relationship of addition and subtraction. The resource provides self-check exercises and timed learning games to practice the concept.

Find definitions and examples of commutative property, associative property, distributive property, identity property, inverse property, and multiplicative inverse. This tutorial also offers practice exercises for you to complete after...

This site from Washington State University provides properties and rules of addition and multiplication that help with proofs.

Read this tutorial to learn about reciprocal and inverse numbers and how they work.

How well do you know your number properties? Take this quiz and find out what you know or what you don't know. Immediate feedback. Check your answer right online.

This Purplemath lesson includes many different number properties explained by using examples.

The purpose of this task is to assess students' understanding of multiplicative and additive reasoning. Aligns with CCSS.Math.Content.4.OA.A.1 Interpret a multiplication equation as a comparison

Demonstrated in this lesson is that a variable, like a number, has inverses; and what to do with those variables when they have coefficients. Students watch a video tutorial and then take an online quiz.
