Let students monitor their own learning by using this traffic light tent. As a student begins to struggle on the topic he/she can simply take his/her traffic light and change it to yellow (need help, but can continue) or red (need help!). A quick visual/formative assessment for you to monitor their progress and for them to tell you their level of understanding.
Simply print, laminate, fold on lines, and tape the bottoms together. You can add a piece of velcro to their desk and the tent for easy keep .
