Why is this lesson important to me?

Understanding the vocabulary and terms used in math will make it easier for you to be successful in higher-level math courses.

Classifying terms, objects, and information is a skill you will use throughout life. For example, when planting a garden you might need to classify your plants according to their growing season and soil type.

Vocabulary

By the end of this lesson you will be able to correctly use and define each of the terms below.
