• Chapter 7 - Expressions and Patterns
     
    In Chapter 7, we will learn how to write and interpret numerical expressions and plot ordered pairs on a coordinate plane.  We will also learn how to work backward to solve problems.
     
    Vocabulary for Chapter 7:
     
    order of operations: rules that tell what order to follow when evaluating expressions
     
    equation:  a number sentence that contains an equals sign (=)
     
    variable:  a letter or symbol used to represent a number
     
    coordinate plane:  a plane in which a horizontal number line and a vertical number line intersect at the point where each line is zero
     
    origin:  the point where the two axes meet
