Abstract: A method for representing and solving algebraic equations that allows a user to view and solve algebraic equations through a novel user-interface. The user-interface includes a primary cog and a plurality of secondary cogs as parts of a gear system. The primary cog represents a range of outcomes for the gear system and contains a plurality of teeth that is quantitatively greater than a numerical constant of the algebraic equation; amongst the teeth is a target tooth that represents the numerical constant. Each of the secondary cogs represent a term of the algebraic equation and includes a coefficient and a variable. Each of the secondary cogs contains a number of teeth equal to the coefficient. The equation is solved by rotating the secondary cogs until the target tooth is aligned with a fixed pointer where rotation of the secondary cog represents a value input for the variable of a term.

Abstract: An improved method of teaching mathematics which enables students to take an active and enjoyable role in their own learning via an interactive puzzle is disclosed. In the preferred embodiment, each of the ten digits, zero through nine, is “hidden” within one of ten value positions (52).

Mathematical reasoning is intrinsic to the puzzle. Programmable settings (72) allow the teacher to modify the puzzle, including substituting more challenging values in place of the digits (98), supplying more complex functions (106) in place of the four elementary arithmetic operations, and adjusting the format of the answers.

Abstract: A mathematical teaching aid based on a grid system. There are multiple grid based modules meant to teach math concepts from preK thru college level math. There are modules for teaching how to count, addition, subtraction, multiplication, division, and fraction manipulation (addition, subtraction, multiplication, division, equivalencies and LCD.) The system provides a physical, and visual model of math and lends itself to self-discovery/self-assistance by the student. The system is attractive to the student because coloring by the student is a part of the learning process, so the student is having fun while learning. This system exceeds the criteria for an ideal math model. These criteria are discussed in the definitive article (Murata, Aki (2008) ‘Mathematics Teaching and Learning as a Mediating Process: The Case of Tape Diagrams’, Mathematical Thinking and Learning, 10:4, 374-406.) This system is easy to use, inexpensive, and puts the student on math learning auto-pilot.

Abstract: 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.
