This behavior chart works great for my students! I print the red, yellow and green faces out and I then taped and then laminate the three together. You can use just red and green depending on your level of students. I have used both just red and green and all three colors. I use a clip and write each students name on it and depending on the level of the students you can put a picture of each child's face on the clip too. I use the same red and green faces and place them in my name badge to use throughout the day, this way it correlates with the behavior chart in the classroom. See my store for those too. I just folded them in half and place them in an extra sleeve on my name tag. The green and red smiles faces are in a two separate files in my store.
