Another thing you can do is in other areas show her it is not a big deal to skip around and come back to something later.
Got a nasty crusted up cooking pan? fill it with soapy water over to the side to soak and wash the rest of the dishes....no big deal to skip around.
Got a stack of mail to look through? ...no big deal to handle the junk mail first, the easy to handle second and the more difficult mail last.
Have a stack of reading to do? You might want to tackle it shorter to longer or by a different order. The order isn't set in stone you can change your mind.
Just because math problems are numbered 1-20 doesn't mean you have to do them in that order.
