When moving from understanding expressions and equations to using them in word problems, the first step is turning an algebraic expression into words. This may seem to be a straightforward reading of notation, yet there are a variety of ways to write algebraic expression and equations.
Various synonyms for operations can be used and all are technically correct. Writing an equation from a word problem requires similar accuracy. Too often, students misinterpret the words used, and many students are intimidated by the bulk of information presented in paragraph form.
A step process often helps in tackling a word problem. Find the question generally at the end of the problem. Help students to break down the words, word phrases, and sentences into individual parts as shown above. Students tend to focus on the first numbers presented and often subtract or add them without regard to the words used in the text.
By underlining and identifying terms such as combined, four more than, and decreased by, students will pinpoint the operations required. Careful reading is also necessary to identify relationships among numbers. One way to solve equations that students will be familiar with is to find a missing addend.
Inverse operations can also be used to solve equations. Addition and subtraction undo each other. Remind students of the balance scale. Students can check their answers by substituting their result back into the original equation.Found in: 4th Grade • 5th Grade • 6th Grade • 7th Grade • 8th Grade • All Year Long • Mathematics.
