Show the picture of the railway tracks. If a train is coming, they should wait until it passes before crossing the tracks. Then they should cross without delay and watch very closely where they step so that they do not stumble or fall because the tracks might be uneven, slippery, and hazardous. Then do what is right. Have half of the students form a train.
Some students can hold the crossing signs.
The train must not slow down if a car is on the track, but only whistle. Explain to the students that a train can not stop for them. The following activities are designed to give greater variety and reinforce the lesson objective. While reading, have someone hold up the picture. Modify the story for younger students.
