Around 2003, the website won several minor awards from educational publications, including One of the Top 10 educational Web Sites Canada's SchoolNet's in 2003 , the Knot #284 Canadian Mathematical Society, NCTM Illuminations Web Byte (National Council of Teacher of Mathematics), and one of 30 "Desert Island Theorems" of the book: "The Changing ...
NCTM publishes three official journals. All are available in print and online versions. Mathematics Teacher: Learning and Teaching PK-12. According to the NCTM, this journal "reflects the current practices of mathematics education, as well as maintaining a knowledge base of practice and policy in looking at the future of the field.
The net has to be such that the straight line is fully within it, and one may have to consider several nets to see which gives the shortest path. For example, in the case of a cube , if the points are on adjacent faces one candidate for the shortest path is the path crossing the common edge; the shortest path of this kind is found using a net ...
All 11 unfoldings of the cube. A polyhedral net for the cube is necessarily a hexomino, with 11 hexominoes (shown at right) actually being nets. They appear on the right, again coloured according to their symmetry groups. A polyhedral net for the cube cannot contain the O-tetromino, nor the I-pentomino, the U-pentomino, or the V-pentomino.
IllumiNations: Reflections of Earth was a nighttime show performed nightly at Epcot at the Walt Disney World Resort in Bay Lake, Florida. The show utilized fireworks , pyrotechnics , water fountains , fire effects, lasers , searchlights , and a large rotating globe with curved LED screens to create a visual production on the park's World ...

The cube stacking game is a two-player game version of this puzzle. Given an ordered list of cubes, the players take turns adding the next cube to the top of a growing stack of cubes. The loser is the first player to add a cube that causes one of the four sides of the stack to have a color repeated more than once.
Here we usually add the rule that all of the original face planes must be present in the stellation, i.e. we do not consider partial stellations. For example the cube is not usually considered a stellation of the cuboctahedron. Generalising Miller's rules there are: 4 stellations of the rhombic dodecahedron; 187 stellations of the triakis ...
