Pratt based her blocks on a similar but larger-scale block system designed by educator Patty Hill, a follower of Friedrich Fröbel, the originator of kindergarten education. Fröbel's series of 20 age-calibrated educational "gifts" had included a set of eight blocks, sized ½ by 1 by 2 inches, or a 1:2:4 ratio, which could be formed into a cube ...
In graph theory, a branch of combinatorial mathematics, a block graph or clique tree [1] is a type of undirected graph in which every biconnected component (block) is a clique. Block graphs are sometimes erroneously called Husimi trees (after Kôdi Husimi ), [ 2 ] but that name more properly refers to cactus graphs , graphs in which every ...
A block design test is a subtest on many IQ test batteries used as part of assessment of human intelligence. It is thought to tap spatial visualization ability and motor skill . The test-taker uses hand movements to rearrange blocks that have various color patterns on different sides to match a pattern.
In the case of construction plans, such as road work or erecting a building, the supervising workers may view the "blueprints" directly on displays, rather than using printed paper sheets. These displays include mobile devices, such as smartphones or tablets. [14] Software allows users to view and annotate electronic drawing files.
In their book Pivot Table Data Crunching, [2] Bill Jelen and Mike Alexander refer to Pito Salas as the "father of pivot tables". While working on a concept for a new program that would eventually become Lotus Improv, Salas noted that spreadsheets have patterns of data. A tool that could help the user recognize these patterns would help to build ...
The Lego system is the most widely used clamp building block system in the world. Building blocks (also construction blocks) are modular construction parts, usually made of plastic, which can be assembled in a form-fit manner. The basic components are usually cuboid-shaped, cylindrically studded at the top in a grid pattern, hollow-bodied at ...
A simplex graph is an undirected graph κ(G) with a vertex for every clique in a graph G and an edge connecting two cliques that differ by a single vertex. It is an example of median graph , and is associated with a median algebra on the cliques of a graph: the median m ( A , B , C ) of three cliques A , B , and C is the clique whose vertices ...
KEVA Planks is a wooden block construction toy. Froebel gifts are a range of educational materials first used in the original Kindergarten. Montessori sensorial materials are a range of educational materials including wooden blocks. Pattern blocks and Cuisenaire rods are sets of small blocks used in mathematics education and also in block play.
