<p>A tool for teaching and learning multiplication is provided. The tool for teaching and learning multiplication is capable of helping young children or pupils substantially understand a multiplication table consisting of abstract equations and values by having them practically learn the multiplication table using a sensory teaching tool in reality and expanding numbers and calculation from concreteness to abstractness by simply rotating a calculation member if necessary. The tool for teaching and learning multiplication includes: a quadrangular frame, calculation supports (30) mounted parallel to each other in an inside of the frame, calculation members (20) for moving right and left on the calculation supports(30), a stage guide part (40), and a multiplication number-guide part (50). The stage guide part (40) is mounted on a horizontal axis in one side of the frame (l?) to represent a number of the stage. The multiplication number-guide part (50) is mounted on a vertical axis in the one side of the frame 10 to represent a multiplication number.</p> |
