Form a committee, with members that can take on different jobs such as organizing food or finding volunteers. This way no one has to do everything and each part of the cultural diversity night gets its due attention.
Set up booths that feature each culture and ethnic group represented at the elementary school. If you'd like to go one step further, organize booths that have information about other cultures as well.
Decorate the booths. Use pictures of national landmarks in the native land of a particular culture, national flags, and other images that represent each culture. Find volunteers of each culture to run the booths because these people can offer more in-depth information.
Give away informational materials such as brochures, books, computer software programs or coloring books that teach elementary students and their families about the differences between cultures. Seek donations to keep the costs down.
Serve food. Ask parents and community members for donated food items, or advertise the event as a potluck, asking families to bring their favorite meal or snack. For example, an Italian family could bring a pasta dish, and a Mexican family could bring tamales. Set up all the food in one area with serving utensils, plates and napkins. Place trash cans nearby for garbage.
Set out crafts and games that go with specific cultures. This gives students and parents a fun way to get to know each other. Again, donations can keep the cost of the event down.
