My grandson just gives up in working his division problems. He is in the 4 grade and I just cannot find a way to get him interested enough to apply and understand. Can you help me.

perhaps attempt to show him some practical/real world examples where understanding simple division is a tremendous asset. Go over dealing with $, that may get him interested...or find something that he is a huge fan of & somehow apply division to that.

You could also make up work sheets & then time him. If he gets them all correct, or the majority, in x-time, then treat him to a desset or his pick of video to watch, or some play-time. I don't even know what kids in the 4th grade do anymore, but find some sort of slight "star" to congratulate him for his hard work & efforts.
K has some very good ideas. You may also want to check out these computer math games to see if any of them would interest your grandson.
