Unit 1 Introduction to Algebra

 Unit 1 Essential Questions 1 What is a variable and why should they be used if I have numbers to represent quantities? 2 How is using exponents any different (better) than not using exponents? 3 Why is it important that everyone perform operations in the same order? 4 What is the best way to display and analyze data? 5 How can graphs mislead your understanding of data? 6 How can I represent a pattern in a table algebraically?

 Learning Objectives Unit 1Introduction to Algebra Variables in Algebra Evaluate variable expressions Write variable expressions that model the real world. Exponents and Powers Evaluate expressions containing exponents Use exponents in real-life problems Order of Operations Use the order of operations to evaluate algebraic expressions Use a calculator to evaluate real-world expressions (like sales tax) Equations and Inequalities Check solutions and solve equations using mental math check solutions of inequalities in real-life problems A Problem-Solving Plan Using Models Translate verbal phrases into algebraic expressions Use a verbal model to write an algebraic equation or inequality to solve real-life problems Tables and Graphs Use tables of organized data Use graphs to organize real-life data An Introduction to Functions Identify a function and make an input-output table for a function Write an equation for a real-life function.
