The Value of Guess and Check

Guerrero, Shannon M.

Mathematics Teaching in the Middle School, v15 n7 p392-398 Mar 2010

The National Council of Teachers of Mathematics (NCTM) Algebra Standard states that instructional programs at the middle grades should enable students to "represent and analyze mathematical situations and structures using algebraic symbols" (2000, p. 222). Guess and check is a powerful problem-solving strategy that can connect a conceptual understanding of word problems with a symbolic representation. It also encourages independent judgment in the development of number sense. The guess-and-check strategy not only helps students find solutions to word problems, but also creates a habit of mind that enables them to successfully separate and translate the different parts of a word problem into mathematical equations. This approach to solving word problems encourages reflection on the original problem, development of an algebraic statement, and determination of the reasonableness of a solution. This strategy can be used at any grade level and can easily be adapted to the mathematical skills, fluency, and maturity of the students. (Contains 4 figures.)
