A work in progress, CK-12's Algebra I Second Edition is a clear presentation of algebra for the high school student. Topics include: Equations and Functions, Real Numbers, Equations of Lines, Solving Systems of Equations and Quadratic Equations.

CK-12's Texas Instruments Algebra I Teacher's Edition Flexbook allows an Instructor to teach students to better utilize a graphing calculator in understanding the fundamental concepts of algebra.

CK-12 Foundation's Basic Algebra FlexBook is an introduction to the algebraic topics of functions, equations, and graphs for middle-school and high-school students.

This classroom activity presents College Algebra students with a ConcepTest and a Question of the Day activity concerning the effect of the initial value, C, on the y-intercept and position of an exponential function where C<0 and k is an arbitrarily fixed value in f(x)=Ce^(kx

Students match features of exponential and logarithmic functions and then consider which features could change with a transformation. Features include: domain, range, intervals of increasing/decreasing, x- and y- intercepts, end behavior, and asymptotes.

The goal of this task is to develop an understanding of why rational exponents are defined as they are (N-RN.1), however it also raises important issues about distinguishing between linear and exponential behavior (F-LE.1c) and it requires students to create an equation to model a context (A-CED.2

This task presents a contextual situation in which algae is growing in a lake at a rate of doubling every day.  The task asks students to evaluate claims about the extent to which the algae will grow and to create an equation that models the algae growth on the lake.

In this activity, we will explore how the dosage and frequency of a medicine taken affect the amount of medicine present in the blood.

In Zombie Attack, students will organize, display and analyze data to solve practical problems using models of exponential functions. Learners will use knowledge of transformations to write an equation, given the table and graph of an exponential function. In doing so, students will form connections between multiple representations of exponential functions for analysis, interpretation, and prediction.
