MAT 139P – Number Systems Plus Resources

MAT 139P (formerly MAT 139) Course Description

A problem-solving approach is used in the study of sets and number systems. The natural numbers are extended to the rationals, integers, and finally the reals. Topics include elementary number theory, non-decimal systems, numeration, and computational algorithms in the elementary school. The course emphasizes the content/method connection.This course will integrate algebra topics covered on the Praxis II exam required for Elementary Education certification. The course is designed and intended for Elementary Education and Early Childhood Education students only and thus cannot be used to satisfy the Precalculus Mathematics Plus (MAT 155P) or Precalculus Mathematics (MAT 155) prerequisite for Calculus I with Technology (MAT 243).

Course Pre-requisites:Placement at this level or Completion of MAT 099

Credits: 4 (all of which count towards graduation)
