CAER in the Classroom
Let Wally Wise Guy show you how to be safe
Wally Wise Guy is often spotted in local classrooms, letting students know the best way to prepare and handle Shelter-in-Place emergencies.
“I love you! I would like to invite you to
my house to play. We learned how to
stay safe.”
“I gave you a hug. I noticed your big shoes”
“When I hear the siren, I listen and go inside. I shelter and shut.”
