Math 1090 Pre-Algebra

Course Purpose

The purpose of all of the developmental mathematics courses is to support student success academically and beyond by advancing critical thinking and reasoning skills.  Specifically, in pre-algebra as a team we will examine final answers in terms of reasonableness to the given problem and to determine if the answer addresses the original problem (Polya step 4). In addition, we will explore the power of estimation as a tool to determine accuracy of solutions to numeric and or real world problems.

Math 1090 in the Developmental Math Program in the Department of Mathematics at Western Michigan University is a mastery-based course designed to sharpen computational skills involving whole numbers, fractions, decimals, percents, geometric figures and word problems.

Math 1090 is a remedial class that does not provide credits towards graduation.
