One way of reading these subtraction sentences is, "The difference between the yellow and the pink is the white."

Or we could say, "the yellow take away the white is the pink."

The advantage of the Cuisenaire rods is that we can concentrate on the concept of subtraction, without the need for any counting, giving us time to really focus on the relationships. The children have been really good at this!
