Go slow now to go fast later!
Build a solid foundation in math with clear explanations, everyday language, and examples that make the ideas click.
Watch each video, then work through its accompanying worksheet to put your understanding into practice. Answer keys include explanations so you can check your thinking as well as your answers.
Lessons within each series build on one another, so start at the beginning—or revisit a topic whenever you need a refresher.
Lesson 1: What is a Function?
Understand inputs and outputs, and connect equations, tables, and graphs.
Lesson 2: INputs & outputs (and domain & range)
Work backward from outputs to inputs, and understand domain and range.
Lesson 3: f(x) function notation
Understand what f(x) means, why it isn’t multiplication, and how it keeps track of the input that produces an output.
