• The concepts of proportional relationships underlie similarity.<br />

• The level sets of functions of two variables are curves in the coordinate plane.<br />

• Factoring a polynomial function into irreducible factors helps locate the<br />

x-intercepts of its graph.<br />

• Proofs are required to establish the truth of mathematical theorems.<br />

Problem Solving<br />

Problems occur in many forms. Some are simple and routine, providing<br />

practice for skill development. Others are more complex and take a longer time<br />

to complete. Whatever their nature, it is important that the kinds of problems<br />

students are asked to solve balance situations in the real world with more abstract<br />

situations. The process of solving problems generally has the following stages<br />

(Geary 1994; Mayer 1985):<br />

• Formulation, analysis, and translation<br />

• Integration and representation<br />

• Solutions and justifications<br />

Formulation, analysis, and translation. Problems may be stated in an imprecise<br />

form or in descriptions of puzzling or complex situations. The ability to recognize<br />

potential mathematical relationships is an important problem-solving technique,<br />

as is the identification of basic assumptions made directly or indirectly in the<br />

description of the situation, including the identification of extraneous or missing<br />

information. Important considerations in the formulation and analysis of any<br />

problem situation include determining mathematical hypotheses, making conjectures,<br />

recognizing existing patterns, searching for connections to known mathematical<br />

structures, and translating the gist of the problem into mathematical<br />

representations (e.g., equations).<br />

Integration and representation. Important skills involved in the translation of a<br />

mathematical problem into a solvable equation are problems of integration and<br />

representation. Integration involves putting together different pieces of information<br />

that are presented in complex problems, such as multistep problems. However<br />

such problems are represented, a wide variety of basic and technical skills are<br />

needed in solving problems; and, given this need, a mathematics program should<br />

include a substantial number of ready-to-solve exercises that are designed specifically<br />

to develop and reinforce such skills.<br />

Solutions and justifications. Students should have a range of strategies to use in<br />

solving problems and should be encouraged to think about all possible procedures<br />

that might be used to aid in the solving of any particular problem, including but<br />

not limited to the following:<br />

• Referring to and developing graphs, tables, diagrams, and sketches<br />

• Computing<br />

• Finding a simpler related problem<br />

• Looking for patterns<br />

• Estimating, conjecturing, and verifying<br />

• Working backwards<br />
