We compare simple fractions by using visual models (pies or rectangles). In the end, I ask an interesting question about 1/2 of a rectangle cut one way, versus 1/2 of a rectangle cut another way - which will be the bigger piece? Children might not intuitively know that 1/2 of a rectangle will be equal to 1/2 of a rectangle, now matter how it is cut, but I show, using quarters, that the pieces must be equal in size.
