US 2009/0023121 A1 · Word problem solving apparatus

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.
