An apparatus for teaching and learning multiplication is provided to enable a student to naturally understand a multiplication theory by using three dimensional multiplication materials. An apparatus for teaching and learning multiplication includes a rectangular frame(10), plural multiplication support bars(30) and a multiplication material(20). The multiplication support bars(30) are implemented to be in parallel with one another inside the frame(10). The multiplication material(20) is moved in left/right directions with the rectangular frame support bars(30) as moving shafts, and has a shape selected from the group of fruits, animals, candies, and polygons which are symmetrical with respect to a vertical axis of the multiplication support bars(30). The elements of the group serve as a unit of multiplication. A multiplier guide portion(40) is implemented at a horizontal axis at one side of the frame(10). A multiplicand guide portion(50) is implemented at a vertical axis at one side of the frame(10). |
