In this module there is a thorough review of the topic of functions. This module covers five key areas: Definition of a function. Evaluating a function. The structure of linear functions. The structure of quadratic functions. Composite functions.

In this module there is a complete review of the topic of complex numbers. This module covers six key areas: Definition of an imaginary number, Definition of a complex number, Calculating the modulus of a complex number, Adding and subtracting complex numbers, Multiplying and dividing complex numbers, Complex roots of quadratic equations.

In this module there is a complete review of the topic of quadratic functions and equations. This module covers four key areas: 1. Definition of a quadratic function; 2. Definition of a quadratic equation; 3. Solving quadratic equations algebraically; 4. Solving quadratic functions graphically.

Turn the Halloween season into an opportunity to do some math activities! In this module, you'll find a clever collection of arithmetic, algebra, and geometry activities. This module includes video, hands-on activities, and games.

In this lesson students learn how to use the slope formula to calculate steepness. In particular, students learn how to calculate steepness in the context of cycling. Cyclists use a measure called grade to calculate the steepness of a hill or mountain. Students apply their knowledge of slope to the concept of grade.

In this module, students explore a physics-based application of linear functions: Hooke's Law. By exploring the properties of springs, a simple linear model is developed. Students then explore applications of Hooke's Law, from weight scales to bungee cords.

In this module students learn the basics of integers, with plenty of real-world applications to ground their knowledge. Two short videos introduce the topic of integers and how to graph integers on a number line. A real world application of Superconductivity is explored.

In this lesson students apply their understanding of linear functions to an analysis of distance vs. time functions. In particular students will: Define the function for finding distance given a constant speed. Graph the distance function and interpret slope, y-intercept, domain, and range.

When a driver slams the brakes on a car, skid marks are created on the road. Accident investigators can measure the length of the skid marks to estimate the speed of the car. This involves using a quadratic function.

In this module students learn how to solve two-step equations. Students are shown how to solve these equations using the Properties of Equality (Addition, Subtraction, Multiplication, and Division).
