I think I may try that Zigzag. Ours are dreadful at the moment. Noisy, loud screaming at each other. Fighting games and absolutely no respect for toys, staff or each other. Toys are just dropped, thrown or discarded wherever they happen to be. A couple of weeks ago- I honestly thought it was the weather- they were cooped up indoors day after day as soon as we did get outside, the heavens were opening. Then we had a few days of high winds - so thought it was that. But now I'm at my wits end with them. Yesterday we had two slapping each other round the face, taking it in turns to do so.
But its the total lack of respect for resources thats really bugging me- they walk across anything on the floor, stamping on books- we've tried everything.
I got so cross yesterday that I sent them all home with 'next week, we are having no toys out at preschool. Tell your mummies its because you dont know how to look after them' Felt bad after as it's not all (about 6 out of 25 are fine!`) of them, our worst offenders are the older ones. For the first time I am thinking some of these children should not be with us- they really need to be in school- in a more structured environment. Although as soon as staff try to do more structured activities with a group- they are so easily distracted and busy poking and annoying each other it becomes very difficult.
Anyway- I think I may try your bin idea.
