If we want to get the whole message, it is important to use our eyes and look at the person who is talking to us. In the classroom, this is often the teacher, but it might be another student or another adult.
Watch this video. All of the communication happens without a word being spoken. What do we understand about this little boy from his body language and gestures? (and what is the dad communicating to the mom at the end?)
If you were looking somewhere else, would you have noticed all that is happening here?
In this commercial, the dad and the mom are communicating without using any words. (the words are also typed as subtitles on the bottom of the page)
The girls are able to tell exactly what the mom and dad are communicating to one another because they are watching what is going on!
