HHS School System: Mental Exercise – A 14-Week Brain Boosting Journey Grade 4 students across HHS participated in a 14-week mental math programme focused on improving cognitive speed and accuracy. Using the Chisanbop method—a Korean finger calculation technique, students practiced quick addition and subtraction through interactive sessions. Teachers received specialized training, ensuring consistent and engaging classroom delivery. Pre- and post-assessments showed remarkable gains, reflecting the effectiveness of hands-on learning and daily practice. This initiative underscores HHS commitment to innovative, skill-based education that empowers young learners.
