Interpret constants and coefficients in the context of the problem.

Graphs and Functions	Lesson: Demonstrates the connections between formulas and graphs.
Introduction to Functions	Lesson: Introduces the basic ideas needed for understanding functions.
Reading Graphs	Lesson: Demonstrates the connections between formulas, graphs and words.
Function Machine	Activity: Students investigate very simple functions by trying to guess the algebraic form from inputs and outputs. Function Machine is one of the Interactivate assessment explorers.
Linear Function Machine	Activity: Students investigate linear functions by trying to guess the slope and intercept from inputs and outputs. Linear Function Machine is one of the Interactivate assessment explorers.
Simple Plot	Activity: Plot ordered pairs of numbers, either as a scatter plot or with the dots connected. Points are connected from right to left, rather than being connected in the order they are entered.
Slope Slider	Activity: Manipulate a linear function of the form f(x)=mx+b using slider bars. Explore the relationship between slope and intercept in the Cartesian coordinate system.

Solve using tables, graphs, and algebraic properties.

Functions and the Vertical Line Test	Lesson: Introduces students to the vertical line test for graphs of functions.
Graphs and Functions	Lesson: Demonstrates the connections between formulas and graphs.
More Complicated Functions: Introduction to Linear Functions	Lesson: Introduces the basic ideas needed for understanding linear functions.
Data Flyer	Activity: Enter a set of data points, then derive a function to fit those points. Manipulate the function on a coordinate plane using slider bars. Learn how each constant and coefficient affects the resulting graph.
Function Flyer	Activity: A more advanced version of Slope Slider, this activity allows the manipulation of the constants and coefficients in any function thereby encouraging the user to explore the effects on the graph of the function by changing those numbers.
Slope Slider	Activity: Manipulate a linear function of the form f(x)=mx+b using slider bars. Explore the relationship between slope and intercept in the Cartesian coordinate system.
