Create visual aids to show the children. Print off pictures of basic road signs and signals such as a stop sign, yield sign, stop light, walk and do not walk signals. Color these signs the correct color with crayons. Use glue to attach a wooden craft stick to the back of each sign.
Hold each sign up in front of the children and explain its purpose and meaning. Explain the proper action that the children should take when they see this sign. Instruct the children on where the signs and signals will be located along a road, and teach them to always look for signs.
Test the children's retention of the information by instructing the children to line up along one end of the room. Stand at the other end and tell the children to pretend that they are driving a car or walking along a street. While they walk toward you, hold up a sign. Tell the children to take the appropriate action, whether it is to stop, yield, or walk.
Take the children on a walk around the school or your home. Point out road signs and ask the children to identify them and their meaning. Practice crossing the street with the children to familiarize them with the actual signs and allow them to practice following their directions.
