EA-1.3 Apply algebraic methods to solve problems in real-world contexts.

More Complicated Functions: Introduction to Linear Functions

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

EA-1.4 Judge the reasonableness of mathematical solutions.

Functions and the Vertical Line Test	Lesson: Introduces students to the vertical line test for graphs of functions.
Reading Graphs	Lesson: Demonstrates the connections between formulas, graphs and words.

EA-1.5 Demonstrate an understanding of algebraic relationships by using a variety of representations (including verbal, graphic, numerical, and symbolic).

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.
Conic Flyer	Activity: Manipulate different types of conic section equations on a coordinate plane using slider bars. Learn how each constant and coefficient affects the resulting graph. Choose from vertical or horizontal parabola, circle, ellipse, and vertical or horizontal hyperbola.
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.
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.
Possible or Not	Activity: Review the properties of functions by looking at ten different curves and deciding whether or not they meet the criteria for a graph of a function. This activity simply displays the curves - it does not quiz the user.
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.

EA-1.6 Understand how algebraic relationships can be represented in concrete models, pictorial models, and diagrams.

Reading Graphs	Lesson: Demonstrates the connections between formulas, graphs and words.
Directable Fire!!	Activity: Run a simulation of how a fire will spread through a stand of trees, learning about probability and chaos. Parameters: Probability that a tree will set fire to each of its eight neighbors.
Rabbits and Wolves	Activity: Experiment with a simple ecosystem consisting of grass, rabbits, and wolves, learning about probabilities, chaos, and simulation.
Tables and Chairs	Activity: Explore rectangular and straight-line arrangements of tables, calculating the number of chairs needed to surround different arrangements thereby exploring perimeter concepts. Tables and Chairs is one of the Interactivate assessment explorers.
