Abstract: An apparatus and system are disclosed for teaching mathematical concepts and “fact families.” The apparatus comprises an educational toy block configured, in one embodiment, to help young children memorize basic numbers and number facts in an atmosphere focused solely on play. The toy block, in one embodiment, comprises a polygonal-shaped building block having a plurality of faces, wherein a first face features a first mathematical equation and a second face features a second mathematical equation. The toy block may include a display of multiple mathematical equations in order to facilitate teaching children how mathematical operations are related. In a further embodiment, the toy block displays one or more numbers that are numerical elements in a plurality of mathematical equations forming a “fact family.

Abstract: An apparatus, system, and method are disclosed for teaching sequencing principles. An educational toy is provided with a plurality of panels that interlock with each other in a sequential pattern to form a multi-sided enclosure. A coded element may be represented on at least one of the panels. The coded element may be an element in a series forming a sequence to indicate the sequence pattern of the various panels. The sequence code or pattern to open the multi-sided enclosure is encrypted in the structural design of the various panels. Additional educational material may be represented on the various panels. In addition, an object containing educational material thereon may be included in the interior of the multi-sided enclosure.
