My Math Chapter 7: Expressions and Patterns

Updated 1-5-20

​In this chapter, students will use algebraic reasoning to simplify expressions, translate words into basic algebraic sentences, solve for unknowns, and investigate patterns of change both numerically and graphically.

Chapter 7 Objectives:
  • Write and evaluate numerical and variable expressions
  • Simplify expressions using the order of operations
  • Use in/out tables and variable expressions to solve for unknowns
  • Identify and plot ordered pairs on a coordinate plane
  • Interpret patterns of change in graphs
  • Determine whether an equation or inequality is true/false
  • ​
