Two girls were asked if addition helped them play the game. The students looked
at the interviewer blank and stated that they had not used any addition in the game. The
observer continued watching this pair as they played the game.
One of the girls had a
marker on the track for sixths at 4/6 and the computer gave her the fraction 2/6. She
quickly moved her marker to the end goal, saying, "I win." Then she turned to the
observer and said, “I just added! 4/6 + 2/6 is 6/6 or 1 whole.”
