This is Part 2 of this course, which is specifically designed for educators of school-age children aged 3–5. The goal is to strengthen teaching strategies through play, which is used as a tool for natural learning through free play, exploration, and curiosity. This is based on the premise that a child’s natural curiosity is the starting point for meaningful learning, and that play—as a free, enjoyable, and exploratory activity—fosters cognitive, emotional, social, and motor skills. It is the most effective means of transforming curiosity into knowledge and lays the foundation for success in school and daily life. We explore some games and activities that can be adapted both inside and outside the classroom; these types of games and activities foster collaboration, problem-solving, language acquisition, and emotional, motor, and cognitive development.
