Description: 
Interactive sketch with a graph of a direct variation and a slider for k on the left. The slider shows the relationship between the rate, the slope and the constant of variation. There are nine questions that go with the sketch that require the students to move either k or the (x,y) values to solve direct variation problems.

Comment:  Typically,direct variation is an awkward concept for students to grasp. Being able to see what happens to x and y, as well as k really made the difference! My fussiest student loved it!
