The Mortar and Pestle (Pounding Activity) is a Montessori-inspired learning material used to help children develop fine motor skills, hand-eye coordination, and concentration. The activity involves using a mortar (a bowl-like container) and a pestle (a heavy, club-like tool) to pound, crush, or grind various substances, such as herbs, spices, or grains. This activity is designed to allow children to engage in a sensory experience while practicing essential skills for both academic and practical life development.
