I would give the same strategy that I gave to my two year old, and that would be to introduce the clean up song. I would also remind the preschooler that this is 2 year old behavior, hopefully that will influence the child to start using more responsible behavior.

A lot of the other post make great points about discussing the behavior with the student and trying to understand why its happening. I think that if the student is doing this in a non-disruptive way then it could be helpful to establish a specific place where they can dump the toys, minimizing the area would help with clean-up and allow you to start setting boundaries with the student related to this behavior!

As disruptive as dumping toys can be, sometimes young learners want to see and be fully engaged with their toys. Creating a safe place and time when dumping the toys is acceptable will create a structure for the student. Redirection may be necessary but it will not interfere with their creative play. Letting the student know that they must clean up their space after playtime will also minimize the mess afterward.

I would give the student a subtle redirect and set expectations with the child. To add, maybe find another place with the toys or coming up with a compromise. if the student dumps the toys, they pick it up independently or with support.

Before doing anything else, I would first speak with the student individually to try to find out why they are behaving this way and to let them know that doing so is unacceptable. I would certainly also enforce consequences for such behavior, like having the child pick up the toys or not allowing them to play with the toys anymore. If this does not resolve the issue, I would then try either relocating the toys or prohibiting students from accessing them by themselves.

In situations like this, you need to teach the student what the correct procedure is when playing with toys. You should assist him and slowing allow him to be on his own over time.

I would pull the student aside and tell him why it is wrong to dump toys, and if he still persists, I would have a talk with the student’s parents about his behavior.

Don't give them big baskets of toys. Only a handful at a time.

I recommend reminding the student of the classroom rules and expectations. While discussing the rules with child, explain to them that if they continue to dumb toys out of the bins they will lose free time and activities (tablets, computers, etc.) they enjoy doing because they are not following the rules.

Is there enough room in the classroom to put the toys or toy bins out of reach? If so, I would try relocating the toy bins to an area that the student can not reach them. When it is play time, grab an empty basket and only put a few toys (the child selects) into the basket. They may still dump the basket but at least it will be easier to clean up because it is only a few toys.
