Mathematical tile. Mathematical tiles nailed to wooden planks, overlapped and mortared to give the appearance of a brick surface. Mathematical tiles are tiles which were used extensively as a building material in the southeastern counties of England—especially East Sussex and Kent —in the 18th and early 19th centuries. [1]
Cuisenaire rods are mathematics learning aids for pupils that provide an interactive, hands-on [ 1] way to explore mathematics and learn mathematical concepts, such as the four basic arithmetical operations, working with fractions and finding divisors. [ 2][ 3] In the early 1950s, Caleb Gattegno popularised this set of coloured number rods ...
The study of polyomino tilings largely concerns two classes of problems: to tile a rectangle with congruent tiles, and to pack one of each n-omino into a rectangle. A classic puzzle of the second kind is to arrange all twelve pentominoes into rectangles sized 3×20, 4×15, 5×12 or 6×10.
Manipulative (mathematics education) In mathematics education, a manipulative is an object which is designed so that a learner can perceive some mathematical concept by manipulating it, hence its name. The use of manipulatives provides a way for children to learn concepts through developmentally appropriate hands-on experience.
Muggins, sometimes also called All Fives, is a domino game played with any of the commonly available sets. Although suitable for up to four players, Muggins is described by John McLeod as "a good, quick two player game". [1] Muggins is part of the Fives family of domino games whose names differ according to how many spinners are in play.
A 24×60 rectangle is covered with ten 12×12 square tiles, where 12 is the GCD of 24 and 60. ... and can be written as a finite continued fraction [q 0; q 1, ...
In all of these arrangements each sphere touches 12 neighboring spheres, [2] and the average density is π 3 2 ≃ 0.74048. {\displaystyle {\frac {\pi }{3{\sqrt {2}}}}\simeq 0.74048.} In 1611, Johannes Kepler conjectured that this is the maximum possible density amongst both regular and irregular arrangements—this became known as the Kepler ...
Aperiodic tiling with "Tile(1,1)". The tiles are colored according to their rotational orientation modulo 60 degrees. [1] ( Smith, Myers, Kaplan, and Goodman-Strauss) In plane geometry, the einstein problem asks about the existence of a single prototile that by itself forms an aperiodic set of prototiles; that is, a shape that can tessellate space but only in a nonperiodic way.
