Course Overview

Students will gain an understanding of the properties of real numbers, solve linear equations and inequalities, and use data analysis techniques.

In the first half of the K12 Pre-Algebra sequence, students sharpen their computational and problem-solving skills while learning the language of algebra. Students will:

  • Change word phrases and sentences into mathematical expressions and equations
  • Solve equations and inequalities
  • Continue to develop computational skills using fractions and decimals
  • Study circles, polygons, and space figures
  • Add, subtract, multiply, and divide positive and negative integers
  • Solve problems involving percents, ratios, and proportions
  • Draw graphs and compute statistics to communicate about data
  • Compute the probability of an event and combined events
  • Communicate strategies for solving word problems
