Use this file from TeachMouse during indoor recess when you have specific activities and you only want a certain amount of students working in each area. Students move their name onto the acorn with the activity that they want to do, and only one name is allowed in each acorn.
This would also be useful for classroom activities when students need to choose and you want to control the number of students at each center or activity that day.
The squirrel theme will be popular with many elementary age groups. Also, the second page of this file gives instructions for customizing the file to your specific needs.
