Abstract

A method of teaching basic arithmetical calculations is embodied in a novelty electronic graphic calculating device having a user interface for displaying method steps. The method involves displaying two or more collections of individual icons associated with two or more operands; selecting an arithmetical operation to be performed on the two or more operands; regrouping the individual icons into a collection of individual icons associated with an answer to the operation on the operands; and, displaying the collection of individual icons associated with the answer in sets having a maximum of ten icons each. The method permits visual regrouping and carry-over for teaching and learning mental computation of the four basic arithmetic skills of addition, subtraction, multiplication and division.

using the icons of said first and second collections, occupying cells within said display grid with icons to visually represent said answer, each of said cells being occupied by at most one icon, said occupying resulting in a total number of icons within said grid that is equal to said computed answer;

wherein said occupying comprises regrouping the icons from the second collection into two groups, the second group being made visually distinct from the first group, the first and second groups occupying adjacent rows or columns respectively of the grid in order to provide a visualization of arithmetic carry-over,

wherein said occupying further comprises moving the first group of icons and, after a noticeable pause, moving the second group of icons, said pause enhancing the visualization of arithmetic carry-over or of said regrouping,

wherein the regrouping, the moving of the first group of icons, and the moving of the second group of icons are performed using the processor.

6. The method of claim 5, wherein the electronic calculating device further comprises a speaker and further comprising playing musical notes forming a melodic sequence over said speaker in association with said moving.

7. The method of claim 5, wherein said second group of icons being made visually distinct from the first group of icons comprises the second group of icons being displayed in a different color from said first group of icons, in order to enhance the visualization of arithmetic carry-over.

8. The method of claim 5, wherein the moving of the second group of icons comprises displaying an animated character appearing to carry the second group of icons so as to further enhance the visualization of arithmetic carry-over.

9. The method of claim 5, wherein the electronic calculating device further comprises a level of difficulty selector and further comprising receiving user input from said level of difficulty selector indicative of a selected level of difficulty, said selected level of difficulty restricting a set of operands from which either or both of said first and second operands may be chosen.

10. The method of claim 5 wherein said arithmetical operation is multiplication or division and wherein said occupying further comprises coloring each of a plurality of groups of icons in said grid a distinct color, wherein the number of icons in each group is equal to one of the first and second operands and wherein the number of groups in said plurality is equal to the other of the first and second operands.

11. The method of claim 10 wherein said grid is a first grid and further comprising:

displaying on said display a second grid having a number of rows equal to one of the first and second operands and a number of columns equal to the other of the first and second operands, each intersection of a row and column forming a cell; and

moving the icons from the first grid to the second grid such that each of the distinctly colored groups of icons of said plurality fully occupies a row or column of said second grid with one icon per cell.
