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 taking into custody of reasonable-number operations Pages: 335-339 Traditional instruction in reasonable versify focuses on rules and memorization. Teachers often give students instructions such as, To tote up fractions, first find a common denominator, and so summarise only the numerators or To add and subtract quantitative numbers, line up the decimals, then do your calculations. However, Remembering and correctly carrying out these relatively simple rules can be very(prenominal) difficult, however, when students do not have a good abstract introduction in the judicious numbers. Personally, when I was introduced to this new sentiment I was confused almost daily because my teacher pass judgment me to bonny accept what she was saying and to memorize. Interestingly, this article presents computation abilities in acute numbers that were developed by fourth fool studen ts who participated in a research bulge out on the learning of rational numbers (Moss and Case 1999). The goal of this current research project is to foster a flexible, interconnected judgement of the rational-number system. Students begin their investigations of rational numbers by learning almost 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 continue the problem of students having to comparing or manipulate ratios with divers(prenominal) denominators. This accepts children to lose weight on growing their own procedures for comparison and calculation, instead of assay to master a complex set of procedures that might await foreign to them. A irregular advantage o f this instructional come near is that by b! eginning with percents, we allow children to make their first conversions among the different representations...
