APPARATUS AND SYSTEM FOR TEACHING CALCULATION SKILLS

摘要

Provided is an apparatus (110) for teaching calculation skills. The apparatus may include a plurality of beads (215) and a set of columns (220) of the cells (225) being configured to be occupied by one of the beads. The apparatus may include a set of sensors (235) configured to determine occupation of the cells by the beads, and a processing unit electronically coupled to the set of sensors. The processing unit can be configured to receive from a server at least one array of integer numbers. Each of the integer numbers represents an intermediate result of solving of a sequence of mathematical operations displayed to a user; determine, via the set of sensors, occupation of the cells by the beads; translate the occupation of cells to a check number; and compare the check number to a current number in array to determine whether the current operation is solved correctly.
