First, place your 11 noodles in order from shortest to longest on a new piece of paper or cardboard. Your arrangement should look something like this:
Next, remove two noodles at a time, one from each end, and put them to the side:
Continue this process until only one noodle remains. This noodle is the median. Label it "Med":
Notice that the median divides the set of 11 noodles into two groups of equal size -- the five noodles shorter than the median and the five noodles longer than the median. Another way to say this is that there are just as many noodles before the median as there are after the median.
