How cute! I love this idea instead of boring old cupcakes or calendars. I may use Dr. Seuss & other favorite childrens books characters in the train instead of animals. Who knows. The possibilities are endless!
Use "secret" hand signals to have students SHOW you what they need. Each finger means something different, so the teacher can differentiate what kids need when there are 7 hands raised! Great classroom management technique for nonverbal communication.
