Teach your preschoolers one or two rules about stranger safety, and have them draw a picture of the rule. For instance, if the rule is to never get into a car with a stranger, preschoolers may draw pictures of children standing on the outside of a car. If the rule being taught is to always report encounters with strangers to teachers, preschoolers may draw pictures of them talking to the teacher. Provide construction paper and crayons for the students to make colorful images of their stranger safety lesson.
As a class, create a collage of familiar and unfamiliar faces. Prepare a large piece of construction paper and use a marker to make a column for familiar faces and a column for unfamiliar faces. In front of the group of preschoolers, hold up a picture of an unknown person from a magazine, and ask the group to tell you whether or not the person is a stranger. After the students answer "Yes, it is a stranger," glue the picture of the face onto the unfamiliar side of the paper. For familiar faces, use pictures of well-known teachers at the school. At the end of the activity, the class has created an art collage.
Perform stranger safety skits with your preschoolers. Ask for a volunteer from the class, and have the student come to the front of the room to act out a skit with the teacher. The teacher will pretend to be a stranger, and the child will have to use the stranger safety rules to respond to the stranger. Act out various scenarios with the students to give them a sense of experiential learning.
Create safety signs with your preschoolers that are relative to stranger danger. Sign ideas include painting the crossed out word "stranger" on a piece of poster board, or a sign that simply says "no," which can be glued to a ruler to create a sign for individuals to hold up.
