Students will investigate the input/output model for building function tables. Then they will connect tables, graphs, function rules, and equations in one variable. Finally, they will work backwards to determine function rules for given data sets or graphs.
This site has a service for drawing the graphs of all kinds of functions . With Archimy, you will draw the graph of any function and form, just use your imagination. The program must be downloaded and is free.
In this activity students will use the random number generator to generate numbers to make an expression using the correct order of operations when simplified will yield a target number.
Participants review carefully the Pythagorean theorem, prove it
geometrically and algebraically, and use it to solve real-world problems.
Participants focus on the connection between the Pythagorean theorem
and the distance formula, and use the distance formula to calculate
distances between points on a square grid and in a coordinate plane.
This lesson is designed to introduce students to the idea of functions composed of two operations, with specific attention to linear functions and their representations as rules and data tables, including the mathematical notions of independent and dependent variables. Includes input/output table activity.
