a good way to get her to complete the tasks is use a kitchen timer. explain that when it rings it means that the time is up and she has to have completed her work. however, you need to remnd her of how much time she has left. explain time to her and this makes her want to complete the work. get her to choose a novelty timer - teapot, egg shape, fruit / veggie shapes are fun and she will definitely try her best to finish her work in time.
