With the Constemination 4 Kids project, 5th grade and 2nd grade students will discover the logic of computational thinking through the use of programming (coding) in an “unplugged” mode (without direct computer use) using games and hands-on experiences. These activities, in addition to fostering the development of knowledge and skills needed in their future study and work, will bring out in students attitudes of observation and analysis, reasoning and reflection skills, creative spirit, manual skills and collaborative competence in the group.
