Have children write letters to people in the community. They might write to elderly citizens in a nursing home or hospital patients. Ask them to draw pictures and tell a funny story to try to cheer up the recipient. They can recite what they want to say and you can write it down. They might also write to police officers, firefighters or soldiers to thank them for their service. Mail the letters off or have the children deliver them in person.
Read problem scenarios to the children. For instance, tell them a story about a child who is alone and crying in the grocery store. Ask your students what they would do if they were at the store with a parent and saw that child. They can either tell you what they would do or draw a picture about it. Discuss all of the possibilities and tell them the right thing they should do to help. For instance, tell your mom if you see a child who needs help. This is an opportunity to teach children about helping others. It also gives you a chance to discuss the right way to get help from adults, such as calling 911 or asking a police officer or parent.
Have your class put on a skit about being a good Samaritan. Preschoolers may not be able to memorize and recite lines, so you may want to ask them to make it up as they go along. Before starting, explain the story that will be acted out and assign a role to each child. Adults may participate. Act out various situations where it's important to help other people. For instance, one child might play a person who drops her bag on the ground. Another child can come and help her pick up her belongings. Each pair of children can act out a different scenario.
Organize a food drive to benefit a local food pantry. Ask children to think about the kinds of foods that are healthy and non-perishable, like soup and pasta. You might also ask for a list of needed foods from the pantry. Write out a list to send home with children. Have them ask their families to make donations. Each day you can look at the growing pile of food in your box. Ask if a food pantry worker can come pick up the box so he can thank children in person. You can also ask children to get donations of used winter coats for the needy if you live in a cold area.
