Carrot and the Stick. If she doesn't like carrots (reward), give her stick. My DD is computer junkie. If we say that she has to do 3 pages of Math otherwise she won't be allowed to use computer, she will do it in a heart beat. It wasn't easy in the beginning, now she knows that we are firm, she will ask what she needs to do in the morning and get it out of the way and enjoy her day watching phineas and farbs or DSI, club penguin, etc...

Whenever we go on vacation, we tell her that we are doing this to celebrate one of her accomplishment (we are going vacation anyway and she felt that we dedicate this vacation for her). When she memorize multiplcation up to 6, do something (don't tell her ahead). I was on the recieving end when I was younger and it felt great and motivated me more than anything.
