PRODUCT DESCRIPTION

An introduction to solving variable equations that uses fact families as the starting point. These pages make explicit the relationship between parts and whole in any equation: addition, subtraction, multiplication, and division. This minimizes students’ tendency to solve equations ”backwards,” ( e.g., N + 14 = 37, N = 51 ). It also stresses the relative size of the three numbers in an equation, one of which is a total and is necessarily the largest number.

Emphasis is on identifying the known, rather than the unknown, numbers. Once students understand how to identify the two numbers that are known, they can easily write the expression needed to solve the equation.

The process is identical for both addition-subtraction, and multiplication-division equations. The beginning point is simple for students who haven’t encountered variable equations before. An introduction to what a variable is should be done prior to using this.

There are 13 pages of work including explanations and problems for both addition/subtraction equations, and multiplication/division equations. Both sections include some decimal equations, but there is no multiplication or division by numbers less than 1.
