This is an editable powerpoint file that I use in my classroom as a clip chart for our choice time activities. There are a variety of play choices with corresponding numbers for students to put a clothespin or magnet to select their choice. Want to add more choices or more numbers? It's editable, so you can customize it for your classroom.

I hope that this helps keep your play time/free time/choice time/indoor recess structured and allows your students to have independence to make a choice. If you need more things added, please let me know!
