I created these for a class who were taking too long to tidy up after a practical lesson. I had 8 students on x4 tables; I printed a sheet of these for each table; cut out and laminated. Therefore one student on each table was assigned a specific tidy up job. It worked really well; I stood and watched as the whole class was busy tidying up. I then re-used them with other classes. These can easily be adapted to suit the activity you will use them for. And make sure students hand them back to you when they have completed their job successfully!
