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 cadence to foster an misgiving of reasonable-number operations Pages: 335-339 Traditional instruction in reasonable verse focuses on rules and memorization. Teachers often give students operating instructions such as, To tote up fractions, low find a common denominator, then summate only the numerators or To wreak and subtract decimal numbers, disceptation up the decimals, then do your calculations. However, Remembering and properly carrying focalize about out these relatively simple rules sight be very difficult, however, when students do not have a good conceptual demonstration in the judicious numbers. Personally, when I was introduced to this new concept I was confused almost day by day because my teacher expected me to clean accept what she was saying and to memorize. Interestingly, this condition presents computation abilities in coherent numbers that were developed by fourth grade students who participated in a research bulge out on the schooling of rational numbers (Moss and cause 1999). The goal of this ongoing research project is to foster a flexible, interconnected understanding of the rational-number system. Students pose their investigations of rational numbers by accomplishment about percents in the consideration of linear measurement. The encyclopaedism of fractions and decimals comes later and is grounded in students learning of percents. Although this attempt alters the traditional training sequence for rational numbers, it has many an(prenominal) advantages for teenage students.

For example, by gain down with percents rather than fractions, educators postpone the line of work of students having to comparing or check ratios with different denominators. This accepts children to concentrate on growing their own procedures for semblance and calculation, instead of struggling to subordinate a complex set of procedures that might seem external to them. A irregular advantage of this instructional approach is that by opening with percents, we allow children to make their first conversions among the different representations...
