The magnetic addition machine illustrates calculation operations on whiteboards or magnetic boards. The set consists of two cups, a purple funnel with a plus sign, a collecting rail, colorful balls, and a numbered counting strip from 1 to 10 with an equals sign. You place the components on the board, throw the balls into the cups, and let them roll through the funnel. At the bottom, the blue and green balls line up in the rail and directly display the summed result on the counting strip. The system makes addition in the number range up to 10 visually understandable and supports the mathematical understanding of quantities.
