This Demonstration shows some of the ways fractions are related to the integer grid and the slopes of linear functions. It offers an alternative to part-whole region ("pizza") models for introducing fractions in late elementary and middle school. Set the slope of the line by selecting (with the red locator) a point in the integer lattice. Vary
x
(using the blue locator) and observe the values output on
y
. See what you can find out about fractions with different settings.
