Although she is a 1st grade teacher, this teacher's ideas could be used in any grade. I love her idea for the stand with her lesson plans and she share how she organizes many other aspects of the room.
Color clothes pins by soaking in food coloring. In each jar or container, pour boiling water, a tablespoon of vinegar and food coloring drops and mix well. You can use any combination of drops to make varying colors and shades. I used both traditional food colors and the neon food colors to make about a dozen different colors. Add your clothespins and let them soak for at least an hour.
