Hello. I am Teacher Jjonni, your cube education expert! I honed my expertise in the cube while working as a manager at the Korea Cube Association. Since then, I have gained experience teaching cubes across all age groups. I worked as an after-school teacher at an elementary school, teaching not only elementary students but also middle school students during the Free Semester Program. I also taught cubes to preschoolers in one-day classes. :) Furthermore, not content with just teaching children, I have consistently participated in official competitions to improve my own skills and continue to develop further. :) A sense of accomplishment is incredibly important for children. This is because that sense of achievement leads to confidence and ultimately to a child's self-esteem! Just the fact that they accomplished something difficult—something not just anyone can do—on their own strength gives a child confidence and provides them with something to boast about to others! The versatile cube can cultivate spatial reasoning, creativity, memorization, and mathematical ability! Shall we try solving it together?
