How it works ?
This applet generates random linear inequalities with variable on BOTH SIDES.
It also generates inequalities where students end up dividing both sides by a negative coefficient.
Solve each generated inequality on a separate sheet of paper.
Enter the solution set to this inequality on the right side of the applet. As you do, select the appropriate operation on the right side of the applet.
Enter in an exact boundary value in the input box (i.e. enter “1/3” and not 0.33).
If you enter in the solution set to an inequality correctly, you’ll see a big “CORRECT!!!” sign appear.
If you don’t see this sign, go back to your work to see if you can find your mistake!
Repeat this exercise as many times as you need in order to master this concept!
