Organization: North Carolina Standard Course of Study
Grade Band: 8th Grade
Standard Goal: The learner will understand and use linear relations and functions.
| Graphs and Functions |
Lesson: Demonstrates the connections between formulas and graphs.
| | Introduction to Functions |
Lesson: Introduces the basic ideas needed for understanding functions.
| | Translations, Reflections, and Rotations |
Lesson: Introduces students to concepts of transformations.
| 
Scatter Plot |
Activity: Graph ordered pairs and customize the graph title and axis labels. Points are connected from left to right, rather than being connected in the order they are entered.
| 
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.
| 
Transmographer 2 |
Activity: Build your own polygon and transform it in the Cartesian coordinate system. Experiment with reflections across any line, rotations about any point, and translations in any direction. Parameters: Shape, x or y translation, x or y reflection, angle of rotation

| Graphs and Functions |
Lesson: Demonstrates the connections between formulas and graphs.
| | Introduction to Functions |
Lesson: Introduces the basic ideas needed for understanding functions.
| | More Complicated Functions: Introduction to Linear Functions |
Lesson: Introduces the basic ideas needed for understanding linear functions.
| 
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.
| 
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.
| 
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.

| 
Number Cruncher |
Activity: Similar to the original "Function Machine" but lists input and output in a table and will not let the user attempt to guess the rule on without at least having two data points.
|
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.
