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 measurement to foster an apprehension of reasonable-number operations Pages: 335-339 Traditional instruction in reasonable rhythm focuses on rules and memorization. Teachers often give students instructions such as, To labour up fractions, first find a common denominator, past summarise only the numerators or To add and subtract denary numbers, line up the decimals, then do your calculations. However, Remembering and correctly carrying out these relatively simple rules can be rattling difficult, however, when students do not have a good beliefual introduction in the judicious numbers. Personally, when I was introduced to this new concept I was confused almost daily because my teacher expect me to bonny accept what she was saying and to memorize. Interestingly, this article presents computation abilities in clear-sighted numbers that were developed by fourth position students who participated i n a research bulge out on the learning of rational numbers (Moss and Case 1999). The goal of this on-going research project is to foster a flexible, interconnected fellow feeling of the rational-number system. Students begin their investigations of rational numbers by learning astir(predicate) percents in the consideration of linear measurement. The learning 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 advantages for teenage students. For example, by beginning with percents rather than fractions, educators slacken the problem of students having to comparing or manipulate ratios with antithetical denominators. This accepts children to support on growing their own procedures for comparison and calculation, instead of attempt to master a complex set of procedures that might take care foreign to them. A irregular advantage of this ins tructional undertake is that by beginning w! ith percents, we allow children to make their first conversions among the different representations...
