The Fraction Lab

Build any fraction you like

Pick a top number and a bottom number, and watch your fraction appear as bars and as a point on the number line. Try (six eighths), then (three fourths). Try (seven fourths). Try (zero fifths).

First fraction

Top number
3
Bottom number
8

(three eighths) is three eighths.

Less than one half.

Same amount as (six sixteenths) and (nine twenty-fourths).

What it looks like

(three eighths)

013/8

Things to try

  • Make (one half), then (two fourths), then (three sixths). Watch the point on the number line.
  • Keep the top number at 1 and add more parts at the bottom. What happens to the piece?
  • Make a fraction bigger than one. How many bars does it need?
  • With a second fraction: find two that look different but are the same amount.
