Abstract:
A teach-aiding weight set, comprising:a white weight in the form of a cube and weighing 1 gram; a red weight in the form of a rectangular parallelepiped, weighing 2 grams, and provided on four longitudinal outer surfaces with a continuously extended shallow groove to divide said red weight 12 into two equal sections; a light green weight in the form of a rectangular parallelepiped, weighing 3 grams, and provided on four longitudinal outer surfaces with two continuously extended and equally spaced shallow grooves to divide said light green weight into three equal sections; a purple weight in the form of a rectangular parallelepiped, weighing 4 grams, and provided on four longitudinal outer surfaces with three continuously extended and equally spaced shallow grooves to divide said purple weight into four equal sections; a yellow weight in the form of a rectangular-parallelepiped, weighing 5 grams, and provided on four longitudinal outer surfaces with four continuously extended and equally spaced shallow grooves to divide said yellow weight into five equal sections; a green weight in the form of a rectangular parallelepiped, weighing 6 grams, and provided on four longitudinal outer surfaces with five continuously extended and equally spaced shallow grooves to divide said green weight into six equal sections; a black weight in the form of a rectangular parallelepiped, weighing 7 grams, and provided on four longitudinal outer surfaces with six continuously extended and equally spaced shallow grooves to divide said black weight into seven equal sections; a brown weight in the form of a rectangular parallelepiped, weighing 8 grams, and provided on four longitudinal outer surfaces with seven continuously extended and equally spaced shallow grooves to divide said brown weight into eight equal sections; a blue weight in the form of a rectangular parallelepiped, weighing 9 grams, and provided on four rectangular outer surfaces with eight continuously extended and equally spaced shallow grooves to divide said blue weight into nine equal sections; and an orange weight in the form of a rectangular parallelepiped, weighing 10 grams, and provided on four longitudinal outer surfaces with nine continuously extended and equally spaced shallow grooves to divide said orange weight into ten equal sections; whereby when said weights are used in teaching small children mathematics, the specific color, weight, and shallow-groove-divided sections of each of said weights help small children to learn primary mathematical concepts, particularly the concept of weight.
