I use Whole Body Listening (WBL) language every single day. "Listen with your eyes", "Whole Body Listening Check!". It's also a great beginning of the year classroom introduction lesson.
I usually begin the lesson by asking what kids know already about WBL, and then read Whole Body Listening Larry at School. I usually stop after each part and either talk about an example or we practice using that skill to listen.
After reading the book, we review all the parts of the body we use to listen as a group using a visual, and then talk about this activity (you can find on my TPT store) that is simple and easy to use.
I go over the directions: draw the parts of your body you use to listen and send the kids back to complete it individually. I use heart cutouts to make things fun. Depending on the group/age level, you can remove the words at the bottom.
Fun, easy activity.
