Patent number: 10625166Abstract: A sliding loop game with move constraints includes a playing field formed by intersecting strings and loops. Each loop is a self-connected chain of sites. Each string consists of a chain of sites. Both ends of a string are virtually connected in a loop via invisible connecting sites. Each site is occupied by a game object specifically marked by a color, pattern, character or characters, number, image, or any other identifying marks. Game objects in a loop or a string are moveable as a whole group along the respective sites in the loop or string. If the game object at the end-site of a string leaves the string, it reappears in the end-side at the other end of the string. Movement constraints are applied to the game objects by using master game objects. Hints on target positions of game objects and allowed movements directions are indicated on the playing field.Type: GrantFiled: May 29, 2018Date of Patent: April 21, 2020Inventors: Sergey K.

Patent number: 7223102Abstract: A system and method for teaching basic mathematical operations and facts; and more particularly it is an apparatus for development of accurate conceptual models for small children in learning certain math facts for the first time. The present invention takes into account that a true conceptual model must consistently and accurately reflect the target system and consider the characteristics of the children learners. In this invention, every digit of any number gets a familiar yet consistent name; that name can be weaved into story and rhyme throughout the learning process in both the math questions and in the math answers. The consistent “name for a digit” advancement over the prior art is better because it creates a conceptual model to which children can indeed relate. Digit consistency throughout the system, series, or television program, helps teachers create relevant meaningful application activities or associative modus operandi.Type: GrantFiled: May 26, 2004Date of Patent: May 29, 2007Inventor: Larissa Powell

The answer card may express the truth or falsehood of a statement of a corresponding question card, a word or sentence fragment which can be used in combination with an incomplete statement of a corresponding question card to complete a statement, a statement that comprises a correct answer to a question of a corresponding question card and/or a mathematical expression or value that comprises a correct answer to a mathematical expression of a question card.Type: GrantFiled: September 1, 1998Date of Patent: August 29, 2000Inventors: Jack G. Sanford, Sr., Jack G. Sanford, Jr.

Patent number: 6089871Abstract: A method and apparatus for teaching mathematical skills to players of all ages includes a game board having 100 spaces printed on a first board side, the spaces numbered from one to ninety-nine and having one logo space. Each space, in addition, has printed on it a prime number factorization, an exponential representation, or both, corresponding to the number contained within the particular space. Each player rolls a plurality of dice having prime numbers assigned to each die face. The object of the game is for players to score points by occupying board spaces between spaces imprinted with prime numbers. A space is occupied by applying the rolled dice to match a prime number factorization of a particular space, whereupon a chip is placed on the particular space to denote ownership. The dice used to occupy a space are then no longer used for occupying other spaces during a round of play.Type: GrantFiled: March 8, 1999Date of Patent: July 18, 2000Inventor: Andrew P. Jaffe

Patent number: 6077079Abstract: An educational board game which is used with a conventional deck of playing cards. The game includes a board which has a matrix of spaces in vertical and horizontal rows. Some of the rows are guide rows containing suit and numerical value indicia relating to the playing cards. The remaining spaces contain numerical values having a mathematical relationship to corresponding spaces in the guide rows. Each of the remaining spaces is covered by a removable tile that bears the numerical value of the space and one of the suits of the playing cards.Type: GrantFiled: May 22, 1998Date of Patent: June 20, 2000Inventor: Latrell Barnes

Patent number: 6065970Abstract: A method of playing a game which includes (i) a game board which is divided into a plurality of sections such that each of the sections defines a playing location, (ii) a number disposed on each of the playing locations, (iii) a plurality of cards, and (iv) a number disposed on each of the cards is disclosed. The game includes the steps of (a) providing a game player with a multiplicity of the cards, (b) the game player determining if the number indicated on any one of the cards is a first mathematical multiple of the number indicated on any one of the playing locations, (d) removing from the multiplicity of the cards a first card that has the number indicated thereon which is the first mathematical multiple of the number indicated on one of the playing locations, and (e) positioning the first card on one of the playing locations such that the number indicated on the first card is the first mathematical multiple of the number indicated on the playing location on which the first card is positioned.Type: GrantFiled: April 13, 1999Date of Patent: May 23, 2000Inventor: Karen Crawford Elliott

Patent number: RE37212Abstract: A tape measure is provided in which orientation of the primary indicia are varied to allow reading of measurements from either side. A centering strip is provided which gives fractional values corresponding to the primary indicia, thus allowing easy calculation of certain fractions of a given measurement. Other visual aids for improving ease of use are provided, such as stud centering marks, distinct colors and variations in numeral and hatch mark sizing.Type: GrantFiled: December 17, 1999Date of Patent: June 12, 2001Inventor: Forrest A.
