Common Denominators with Fraction Tiles

Build a fraction wall. To find the common denominator of 1/3 and 1/4, make a train with a 1/3 tile and a 1/4 tile. Drag the train to find a row whose tile edges align with all the tile edges of the train. The row of twelfths has edges that align with all the edges of the train, so 12 is a common denominator of 1/3 and 1/4.
