Description: Sal uses same-sized wholes to show equivalent fractions. This hexagon right over here, the whole thing is filled in with this pink color. Now, what I want you to think about is, which of these other hexagons have 2/3 filled in? So, when you're thinking in terms of thirds, and here we're thinking in terms of 2/3, literally two thirds, what we think about is dividing things into three equal sections.*Teacher Advisor is 100% free.
