Apart from activities connected with traffic that are conducted during lessons, pupils from grades 4-6 can learn in the Green Classroom. Fourth-grade pupils participated in such a lesson and the topic was “Road Users”. The lesson in the Green Classroom gave us the possibility to monitor traffic, indicate road users’ proper and improper behavior and divide road users into pedestrians, passengers, drivers and cyclists. We could check if their behavior was in conformity with the Highway Code. It was great.
