Abstract
The arithmetic educational tool utilizes a container having a main chamber and two extended chambers from the main chamber to visually demonstrate addition and subtraction. Objects placed with the container will move from the main chamber into the extended chambers when the container is tilted and thereby break the number objects in the main chamber into parts. The container is bifurcated, having the two extended chambers branching off of from the main chamber and thereby causes a random splitting of the number of objects into each of the extended chamber. Conversely, objects placed in each of the extended chambers can be added when the chamber is tilted to cause the object to move from the extended chambers into the main chamber. One or more of the chambers may have an obscuring feature, such as a color or slidably cover, that enables obscuring the number of objects therein.
