I am a former math instructor from Korea, currently teaching 3rd-grade math, and a proud mom of a 7-year-old. Throughout my career, Iβve deeply realized that math is a language built entirely on its foundations. If the foundation is rock-solid, a child can conquer any level of math later on; but if it shakes, everything collapses. Seeing many children struggle in classrooms due to gaps in early concepts inspired me to create resources that block those gaps before they even start.
