These hand signal posters coordinate with the other ocean themed products in my store. Teach these hand signals to your students at the beginning of the year. Students can use these instead of raising their hands. With these hand signals, students are able to communicate their needs/ideas without having to interrupt the classroom conversation.
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.
