Abstract: A set of blocks used as an aid for teaching mathematical concepts, in which blocks of different sizes are provided with characteristic dimensions that bear a relationship to preselected numbers in the Fibonacci series. The Fibonacci series is defined as an infinite sequence of numbers starting with 1 that builds by adding the present number to the prior number to form the next number in the series. The first part of the series progresses: 1, 1, 2, 3, 5, 8. 13, 21, 34, 55, . . . , with 0 being understood as the number prior to 1. The series is related to the Golden Ratio of approximately 1:1.618, a ratio found in nature and in certain works of art, by the ratio of adjacent numbers, after thirteen, in the series. The blocks can be used to teach students mathematical concepts such as pattern recognition, the Fibonacci series and related Golden Ratio, and the interrelations between mathematics and other disciplines such as biology, botany, and architecture.
