Fractions with cups

I made fractions out of plastic cups. The fractions I made were quarters and eighths.

First I made quarters. I drew a line on the cup and then I cut it into halves. Next I drew another line from the halves to make quarters.

Afterwards I made eighths. I made quarters and then I cut the quarters into halves and that made eighths.

Here is a slide that shows quarters and eighths that are made out of cups.
