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 mistrust of reasonable-number operations Pages: 335-339 Traditional instruction in reasonable measure focuses on rules and memorization. Teachers often give students instructions such as, To stuff up fractions, first find a common denominator, so summarise only the numerators or To add and subtract decimal fraction numbers, line up the decimals, then do your calculations. However, Remembering and mightily carrying out these relatively simple rules can be genuinely difficult, however, when students do not have a good abstract introduction in the judicious numbers. Personally, when I was introduced to this new apprehension 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 wise numbers that were developed by fourth sucker students who particip ated in 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 agreement of the rational-number system. Students begin their investigations of rational numbers by learning rough 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 th an fractions, educators table the problem o! f students having to comparing or manipulate ratios with unalike denominators. This accepts children to centralise on growing their own procedures for comparison and calculation, instead of seek to master a complex set of procedures that might calculate foreign to them. A irregular advantage of this instructional undertake is that by beginning with percents, we allow children to make their first conversions among the different representations...
