Abstract (type = summary)
In this clip from 4th grade classroom study, students discuss the placement of numbers between zero and one on a number line. A debate ensues as to how many numbers exist between zero and one. Andrew suggests that a microscope can show more numbers than might be visible to the eye. Michael and Erik argue that the line would need to be made larger to include more numbers. Alan maintains that in any given interval, there are infinitely many numbers.
