I don't think there's any formula for this sort of exercise. You just need to fiddle around with the measurements until you note a sequence of pourings and dumpings which will lead to the amount you want. For instance, if you fill the 3-cup and pour this into the 5-cup, how much empty space is left in each of the containers? Can this result lead anywhere useful? And so forth.
Have fun!

How about this- 5x+ 3y= 1. Euclidean algorithm- 3 divides into 5 once with remainder 2: 5- 3= 2. 2 divides into 3 with remainder 1: 3- 2= 1. Replace that "2" in the second equaton by 5- 3: 3- (5- 3)= 2(3)- 5= 1.I don't think there's any formula for this sort of exercise.

Fill the 3 cup measure. Pour that into the 5 cup measure. Fill the 3 cup measure with water. pour that into the 5 cup measure until the 5 cup measure until it is full. That leaves 1 cup of water in the three cup measure.
but not for any 5th graders I know.

I wrote that in response to Stapel's "I don't think there's any formula for this sort of exercise."
