## Course Description

Elementary Topics in Mathematics I and II is a sequence for majors in elementary education and related fields. The purpose of the course sequence is develop mathematical topics usually taught in grades pre-K-5 to a depth required for future elementary educators (and related fields) to establish professional expertise. The courses are taught through an inquiry approach that focuses on problem solving and discussion. Math 1101 focuses on the development of arithmetic and number systems, including whole numbers, integers, and rational numbers; and foundations of number theory. Math 1102 focuses on statistics and probability; ratios and proportional reasoning; algebraic reasoning; measurement; and properties of two-dimensional and three-dimensional objects.

Key themes include

- explaining and justifying standard and nonstandard algorithms for basic arithmetic operations learned in grades preK-5;
- students' construction and critique of their own ideas and others' ideas; and
- using manipulatives to represent and justify algorithms.

Satisfies Tier I requirement for elementary education majors only. Does not apply to Arts & Sciences natural science requirements.
