You may well be expecting your daughter to do things that are still beyond her developmental abilities. She won't learn how to divide fractions until an extensive list of other skills are learned first, and she won't get a single one until she's ready.
My husband just had a discouraging time trying to teach 3rd-5th graders a Sunday school lesson that was simply too abstract for them. (I warned him!) The kids went bananas, wrestling under the tables, doodling on the whiteboard, throwing things and poking each other. These are normally cooperative, polite kids. He didn't realize why they were so off-task until he talked to a couple of the other parents afterward. They said, "You were expecting my kid to learn WHAT?" He won't make that mistake again. (Well, actually he will – he just showed me version B of the same abstract ideas for next Sunday. Sigh.)
A gentle suggestion – once we start labeling kids (stubborn, disrespectful, bad-tempered, etc.), they start living down to the ways we identify them. When we treat every day as a new opportunity to learn our child's needs and capabilities, and work from there, everybody has a better time.
