North Carolina Standard Course of Study
Grade 8
Number and Operations, Measurement, Geometry, Data Analysis and Probability, Algebra:
COMPETENCY GOAL 5: The learner will understand and use linear relations and functions.
Calculating...
Lesson  (...)
Lesson: Introduces students to the vertical line test for graphs of functions.

Lesson: Demonstrates the connections between formulas and graphs.

Lesson: Teaches distinguishing between possible and impossible graphs of functions as well as causes of graphical impossibility.

Lesson: Introduces the basic ideas needed for understanding functions.

Lesson: Introduces the basic ideas needed for understanding linear functions.

Lesson: Introduction to various algorithms for solving single-variable, linear equations.

Activity  (...)
Activity: This activity helps you understand how to balance an equation. You input the term and the operation. The activity uses that term and operates on both sides of the equation. It then displays the resulting equation. Equation Solver is one of the Interactivate assessment explorers.

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.

Activity: Students can create graphs of functions entered as algebraic expressions -- similar to a graphing calculator.

Activity: Create graphs of functions and sets of ordered pairs on the same coordinate plane. This is like a graphing calculator with advanced viewing options.

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.

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 without having at least two data points. Number Cruncher is one of the Interactivate assessment explorers.

Activity: Students investigate linear functions with positive slopes by trying to guess the slope and intercept from inputs and outputs. Positive Linear Function Machine is one of the Interactivate assessment explorers.

Activity: Similar to other "flyers", Slope Slider uses slider bars to explore the effect of the multiplier and constant on a linear function of the form f(x)=mx+b. Explore the relationship between slope and intercept in the Cartesian coordinate system.
