The dolphin class (four-year-old) was introduced to creating a program using function blocks to climb the mountain “Kokkyo no Yama.” They were taught how function blocks can make the program shorter and easier to understand by breaking down the problem into smaller parts. The children also learned to use arrows, ladders, and return blocks to navigate the obstacles on their way to reaching the mountain’s summit. It was a thrilling and educational experience for the young learners as they applied their newly acquired knowledge to complete the task successfully.
