traffic light = semaforo :) make your own traffic light! to go with your cardboard car and cardboard gas station with a pump that actually fits to the car! I love how this women comes up with these ideas!
I would use this idea as a centers for dramatic play for my unit. This center aligns with the standard SS.G.2.K Identify and explain how people and goods move from one place to another. It also aligns with my objective: Students will be able to describe how railway travel began moving goods and people.
