Subtracting Fractions (like denominators) with Pattern Blocks

Subtraction can be thought of as removing one quantity from another. To subtract 2/3 – 1/3, represent a whole as a yellow hexagon and the minuend 2/3 as two blue rhombi. Since the subtrahend is 1/3, remove one blue rhombus. There is one blue rhombus remaining, so 2/3 – 1/3 = 1/3.
