Determine the slope of the line that cockroaches are crawling along to destroy them SEE MORE
 
3. Explore Families of Functions.

Click Image to Enlarge

 
Explore how changing constants affects the graph of the corresponding function.  SEE MORE
 
4. Families of Functions.

Click Image to Enlarge

 
Graph-description match game. Some items may correspond with several descriptions, but there is only one correct arrangement of all of the items SEE MORE
 
5. Function Machine.

Click Image to Enlarge

 
Students investigate very simple functions by trying to guess the algebraic form from inputs and outputs. This activity allows the user to explore simple linear functions; the function is determined by looking for patterns in the outputs SEE MORE
 
6. Linear Function Machine.

Click Image to Enlarge

 
Students investigate linear functions by trying to guess the slope and intercept from inputs and outputs SEE MORE
 
7. Model Algebra.

Click Image to Enlarge

 
Model the equation by dragging number and x tiles to the scale. Press the Check button to see if your model is correct. There are 6 step by step problems to solve. SEE MORE
 
8. Mystery Operations.

Click Image to Enlarge

 
The computer will give an operation, and you can try your wit at solving the mystery. To start, type a number in each of the boxes and then press Calculate. SEE MORE
 
9. Number Cruncher.

Click Image to Enlarge

 
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. This activity allows the user to explore simple linear functions; the function is determined by looking for patterns in the outputs. Whole Number Cruncher records each input and output in a window.  SEE MORE
 
10. Positive Linear Function Machine.

Click Image to Enlarge

 
Students investigate linear functions with positive slopes by trying to guess the slope and intercept from inputs and outputs.  SEE MORE
 
11. Shuttle Mission.

Click Image to Enlarge

 
Teams of Zogs are being sent to explore distant galaxies. To ensure a perfect payload, the exact weight of each Zog must be known. Use one or more strategies to solve each Zog puzzle. We suggest you watch the video (the link is right above the game) to learn how to play.  SEE MORE
 
12. Spy Guys Interactive - Balancing Equations.

Click Image to Enlarge

 
Watch the video and respond at various places SEE MORE
 
13. Teacher Dodge Ball.

Click Image to Enlarge

 
Fill-in numbers on an equation. Each blank of the equation stands for a number on a teacher. Hit the teacher with the number that goes next in the equation by clicking on them.  SEE MORE
 
14. Whole Number Cruncher.

Click Image to Enlarge

 
Similar to "Number Cruncher" but only generates multiplication and addition functions to avoid outputting any negative numbers.This activity allows the user to explore simple linear functions involving whole numbers; the function is determined by looking for patterns in the outputs. Whole Number Cruncher records each input and output in a window. SEE MORE
