This section of the website, Appetizers and Lessons for Mathematics and Reason, written by Alan Selby, PD. (see also Scout Report for Math, Engineering, and Technology, May 24, 2002) offers lesson ideas for teaching linear equations in high school or college. The approach uses stick diagrams to solve linear equations because they "provide a concrete or visual context for many of the rules or patterns for solving equations, a context that may develop equation solving skills and confidence." The idea is to build up student confidence in problem solving before presenting any formal algebraic statement of the rule and patterns for solving equations. Links to related chapters from his book, "Three Skills for Algebra," are also provided.
