I would try and provide incentives periodically in order to encourage students to want to clean up. Examples: best organizer, most helpful, fastest cleaner, etc. Prize could be an addition to an already established awards system or maybe have a goodie box in which winners can choose one prize from.

Maybe you could make your clean up time your exit ticket. For example, all the students have to pick up something before they leave the classroom.

I have a point system that I use with my students. The first team to finish cleaning up recieves 5 points, The second team gets 4 points and the third team gets 3 points.Only if their areas are completely cleaned up properly and in the right place. These points add up daily and at whichever group has the most points at the end of the week gets a prize. It encourages the teams to work together and gets things cleaned up quickly. It also teaches students that puttingbthings up in an ordely manner is important.

It may be a good idea to let those students know for every minute passed the clean up time they take to put everything away is a minute away from center/recess. So if the student decides to take five extra minutes to complete clean up, take those five minutes away from an activity they enjoy.

Maybe you could use the strategy where you use their time to make them clean up. For example, if they can't clean up correctly when it is time, they will have to clean up before playing at recess or no playing at all.

My solution would be to offer a reward to the students if they clean up and eventually remove the reward by having the teacher verbally reward the students.

For younger students a money system would work great for rewards that can be bought like and extra center time or computer time at the end of each wee. This means each student has control of making money or losing money. If directions are not followed they will have to pay for the bad behavior while others are being paid for proper behavior.

When I worked with first graders, the students were assigned specific jobs for clean-up. Two students would be in change of library clean-up, another two would clean-up underneath the desks, two students would be in charge of the computer area, two were designated to clean up other parts of the room, etc. These jobs would change every month therefore it was fair. If a student did not do their job, they lost privileges such as turning their green card to yellow. If they continued to refuse to clean, their card would flip to red which meant a phone call home. This typically got all the students to participate in the clean-up process.

I would let students know at the start of the centers that they cannot participate if they are not willing to clean up. If that did not work, I would either send them to a timeout corner for a few minutes or let them explain to me why they did not want to clean up in front of their fellow classmates.

I think you shouldn't do the centers until they are willing to clean up or have the centers but have the students clean up who usually don't help.

I would try to make clean up time fun for the students, signal clean-up time with music.

I would have a prize for students who pick up the most trash. This will encourage all of the students to pick up trash and get the most possible in order to earn the prize. You could also do "mystery trash" where the students have to pick up trash and the person that picks up the mystery piece, a piece that you randomly saw, gets a prize.
