Jenga Jenga Jenga is a game of physical skill created by Leslie Scott, and currently marketed by Hasbro. Players take turns removing one block at a time from a tower constructed of 54 blocks. Each block removed is then placed on top of the tower, creating a progressively taller and more unstable structure. The name "jenga" is derived from "kujenga", a Swahili word which means "to build".

Like the traditional set, all the angles are multiples of 30°. Pattern Blocks Pattern Blocks are one of the mathematical manipulatives developed in the 1960s by Education Development Center as part of their Elementary Science Study project. They are both a play resource and a tool for learning in mathematics, which serve to develop spatial reasoning skills that are fundamental to the learning of mathematics. Among other things, they allow children to
