Eureka Math is based on the theory that mathematical knowledge is conveyed most clearly and effectively when it is taught in a sequence that follows the "story" of mathematics itself. In A Story of Functions , our high school curriculum, this sequencing has been joined with methods of instruction that have been proven to work, in this nation and abroad. These methods drive student understanding beyond process to deep mastery of mathematical concepts. The goal of Eureka Math is to produce students who are not merely literate, but fluent, in mathematics. This teacher edition is a companion to Eureka Math online and EngageNY. Sequence of Algebra II Modules Module 1: Polynomial, Rational, and Radical Relationships Module 2: Trigonometric Functions Module 3: Exponential and Logarithmic Functions Module 4: Inferences and Conclusions from Data
