Teach children about the different types of families people have. Ask each child to bring in a family picture, or just have them draw pictures of their families. Help each child label their picture with the names of their family members and their relationship to the student. Post the pictures on the bulletin board and gather together to look at it. Ask each child to explain who her family members are. Children should see that every family is different, whether there are two parents, one parent or only grandparents.
Help children see the ways they are the same and the things that make them different by making a large paper flower. Cut out a circle to post at the center of the board. Cut out a long, skinny flower petal for each child. The petals should all fit around the circle without covering one another. On the circle at the center of the flower, write down all the things that make us the same, such as the fact that we all eat and wear clothes. Give each child a petal and help him write things that make him unique and different from others. Hang the petals around the circle.
Even if children haven't yet encountered anyone with a disability, they will at some point in their lives. Expose children to differences people can have in their appearance. Find photos from magazines or online that show people who may not look "typical." Use pictures of people who have Down's Syndrome or are sitting in wheelchairs. You may also be able to find pictures of people who have scars, braces or who have lost their hair. Use a combination of children and adults. Post all the pictures on the bulletin board.
When they're in preschool, children may not realize there are other types of people in other countries. Create a bulletin board featuring children from other cultures. Hang pictures of children from other countries. Under each picture, write the name of the country and some information about what it's like to live in that country. For instance, list typical foods or types of houses that are found there. Use photos of these things if possible. Children will learn about people of other races and cultures.
