It is unclear and unspecific on the degree of "Housekeeping" needs to be done, but I presume here generally works involve only to make classroom neat, tidy, presentable and conducive to learning.
Learning is not and should not be restricted to only academic and books, it should involve natures like responsibility, morality, and compassion, and practicals like being neat, orderly and environmentally responsible.
In this case, the youngs must learn to be independent, sensitive and responsible in things around them, especially things they use or involve in their daily activities, it is part of being healthily responsible.
But of course, I also urge the teacher to get involve physically so to set a good example.
If the intention and objective is clear and positive, I can't see how I can or should oppose such an activity to be including in the learning process.
Basically don't spoil your kids by being overly calculative in responsibilities, they will learn to be one when they grow up, and they will apply what they learn to you in return, one day.
