  • Patent number: 7909608
    Abstract: The present invention provides an apparatus that assists a student with learning how to solve word problems, including cash flow type problems, by using the sense of touch to establish a greater pattern of formula recognition and usage. The word problems include a finite set of constant values for a predetermined number of variables. The apparatus includes a preliminary equation that is presolved for a particular set of values. A final equation is also presolved for the particular set of values. The preliminary equation and final equation are movably placed onto a work area which preferably includes a measurement line.

  • Publication number: 20090023121
    Abstract: The present invention provides a method and apparatus which assists a student in their approach and understanding to solving algebraic word problems. The invention includes a predetermined set of word problems. The student solves the word problem by selecting appropriate rate bars which are responsive to a selected word problem and placing the selected rate bars in proper placement with respect to a measurement line. The student also selects the proper equation, which also includes pre-solved solutions for the selected word problem. The student thus solves the problem through the use of the rate bars alone or in conjunction with a parallel solution provided in the pre-solved equation.
