Patterns

 Patterns allow us to generalize relationships within a set of data Variables and Expressions

 A variable is a symbol used to represent a value. An expression is a mathematical phrase that uses numbers, variables, and/or operations. Equations and Inequalities

 An equation is a sentence that has two equal mathematical expressions. An inequality is any mathematical sentence that is not an equation. Functions

 A function is a relationship in which the value of one variable depends on the value of another variable; each first value may be paired with one and only one second value. Ratios, Rates, and Proportions

 A ratio is a comparison of two of the same measurements.  A rate is a comparison of two different measurements.
 A proportion is a comparison of two equivalent ratios. Multiple Representations

 A single mathematical concept can be represented in a variety of forms such as symbols, words, graphs, tables, and equations ... Data Analysis

 The collection and organization of information into a form that is easily understood. 8th Grade Math Home > Teacher Resources > Mathematical Power for All Students K-12 > Part III - Algebraic Thinking Strand
