Finger Counting Number Blocks is a set of teaching aids that combine "finger counting" with "physical blocks" for up to ten operations. Each piece is printed with 0-9 numbers and corresponding finger count on the front, and the back is a removable protrusion. Children can increase or decrease the number of protrusions by pressing with their fingers, and the number changes synchronously. Through the sensory interaction of "press, count, and spell", intuitively understand the decomposition and synthesis of numbers, addition and subtraction, and rounding methods. Lightweight and drop resistant, can be held with one hand, suitable for kindergarten to first grade classrooms, home tabletop games, and special needs children's sensory training.
