A review of the article "Introducing percents in linear measurement to foster an understanding of rational-number operations" A critical reading

Teaching Children Mathematics; Feb 2003 Introducing percents in painsar measuring rod to foster an misgiving of reasonable-number trading operations Pages: 335-339 Traditional instruction in reasonable verse focuses on rules and memorization. Teachers often give students instruction manual such as, To tote up fractions, start find a common denominator, then carry up only the numerators or To add and subtract decimal numbers, suck up up the decimals, then do your calculations. However, Remembering and properly carrying give away these relatively simple rules grass be very difficult, however, when students do not have a good conceptual presentation in the judicious numbers. Personally, when I was introduced to this new concept I was confused almost perfunctory because my teacher expected me to comely accept what she was saying and to memorize. Interestingly, this denomination presents computation abilities in demythologised numbers that were developed by fourth grade students who participated in a look place out on the educational activity of rational numbers (Moss and facial expression 1999). The goal of this ongoing research project is to foster a flexible, interconnected understanding of the rational-number system. Students grow their investigations of rational numbers by discipline about percents in the consideration of linear measurement. The encyclopedism of fractions and decimals comes later and is grounded in students learning of percents. Although this attempt alters the traditional teaching sequence for rational numbers, it has many another(prenominal) advantages for teenage students.

For example, by origination with percents rather than fractions, educators postpone the riddle of students having to comparing or wangle ratios with different denominators. This accepts children to concentrate on growing their own procedures for comparing and calculation, instead of struggling to keep down a complex tag of procedures that might seem irrelevant to them. A irregular advantage of this instructional approach is that by stock with percents, we allow children to make their first conversions among the different representations...
