This site contains an interactive tool that allows the user to 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.
Type of Material:
This site can be used for demonstrations or for individual student practice.
Identify Major Learning Goals:
The purpose of the site is to help students recognize the patterns used to determine linear function.
Target Student Population:
Can be used for students in algebra classes up through all higher-level math courses.
Prerequisite Knowledge or Skills:
Basics knowledge of linear equations and graphs of lines.
This module allows the user to explore simple linear functions. A student running the activity determines a linear function in slope-intercept form by looking for patterns in the outputs.
Only integers can be used as coefficients in linear functions.
Potential Effectiveness as a Teaching Tool
The site can be used as a part of in-class demonstration or a self-guided activity. A list of suggested activities with this tool is given under Instructor tab. A set of links to related topics is a big plus.
Ease of Use for Both Students and Faculty
A user can starting working with this tool right away by changing input parameters and executing the applet.
In order to understand the activity one must read the Learner tab first.
