Math 1100 Algebra I

Purpose of Math 1100

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 Algebra I, as a team, we will create and critique explanations and justifications.  We will also determine which tools/strategies are needed to complete an argument.  A theme throughout the semester is to examine statement to determine if it is sometimes true of always true.  Then justify justify the claim with examples if the statement is sometimes true or complete justification if the statement is always true.

The Developmental Math Program in the Department of Mathematics at Western Michigan University offers Math 1100, a mastery-based algebra course covering the arithmetic foundations of algebra, properties of real numbers, linear equations and inequalities and systems of linear equations.

    There are many online videos on Algebra I topics. As with anything viewed on the Web, one should first sift through and determine which information is of value and actually correct. The director of the Developmental Mathematics Program recommends Algebra I students view the Khan Academy videos for Pre-Algebra and Algebra I.
