A box with 2/3 cup of cornmeal was used to make pizza. Shelly used 1/4 of the box of cornmeal. Use a rectangle to draw a model to match your expression. What fraction of a cup of cornmeal did she use for the pizza?

1/4 * 2/3 = 1/6
divide rectangle in 12 boxes
entire rectangle is a cup
block off 1/3 which is 4 of the 12 boxes
the remaining 8 of the 12 contains 2/3 cup
use 1/4 of the 8 remaining
which is 2 of the original 12
which means using 2/12 = 1/6
