Learning tools for learning the composition of numbers and the imposition of payments and for displaying the partial -whole relationships in the initial arithmetic building

摘要

Learning tools for computing operations in the initial arithmetic construction as well as for learning the composition of numbers and the imposition of payments and representing the partial -whole relationships of natural numbers, characterized by:differently long frame elements (100, 102, 103, 107, 108),which, by their longitudinal dimensions, represent the natural numbers from one to ten, with each deepening (250),in which a frame -shaped surface (200) is arranged, on which different long inserts can be placed (802, 805) and at least one hole (500, 550),with the different length of inserts (802, 805),which, by their longitudinal dimensions, also represent the natural numbers from one to ten, are adapted to the deepening of the frame elements and the insert plates and thus also the deepening of the frame elements have a proportional relationship to the frame elements.
