Equivalent Fractions Intro
Different names, same size
Loading...
Do 1/2, 2/4 and 4/8 — different names — really have the same size? Tap “Split” and every part is cut in two: the total parts and the shaded parts both double while the shaded length stays exactly the way it was. Tap “Merge” to undo. Going back and forth gives a first look at equivalent fractions: new names, same amount.
Split the same shaded bar into finer parts: the number of parts doubles, the shaded parts double, yet the shaded size never changes. Watch 1/2, 2/4, and 3/6 name the very same amount, and meet equivalent fractions.
