I would talk with her K teacher about adjusting her work... when my son was in K he was given a stack of other work in his chair pocket, and when he complete the regular class work, he would move onto that work (it was stuff she had gotten from the 1st grade teacher.) This worked quite well for his K year. The teacher also had him be her 'helper' quite often - run errands to the office, pass out papers, and sometimes she would have him help other students.
