Module 1: Expressions
During your math studies, you have encountered many different types of expressions, some verbal, such as “the product of three and a number,” and some algebraic, such as “x + 7y.” In this module, you will become an expert on translating expressions from verbal to algebraic and vice-versa. You will also evaluate expressions for given replacement values.
Getting Started
How many algebra vocabulary words are you familiar with? Can you define terms such as absolute value, simplify, cube root, and radicand? Take a moment to evaluate how well you know some of the terms you will constantly use in algebra. As you play Familiar Terms Tic-Tac-Toe, try to get three circles in a row. Make sure to review the terms and their definitions at the end of the interactivity. Click the player button to get started.
