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 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 operating instructions such as, To tote up fractions, origin find a common denominator, then resume only the numerators or To chip in and subtract decimal numbers, pipeline up the decimals, then do your calculations. However, Remembering and properly carrying push through out these relatively simple rules fecal matter be very difficult, however, when students do not have a good conceptual grounding in the judicious numbers. Personally, when I was introduced to this new concept I was confused almost perfunctory because my teacher expected me to fine accept what she was saying and to memorize. Interestingly, this member presents computation abilities in sensible numbers that were developed by fourth grade students who participated in a look for bulge out on the learn of rational numbers (Moss and result 1999). The goal of this ongoing research project is to foster a flexible, interconnected understanding of the rational-number system. Students expire off their investigations of rational numbers by nurture about percents in the consideration of linear measurement. The erudition of fractions and decimals comes later and is grounded in students learning of percents. Although this attempt alters the traditional statement sequence for rational numbers, it has many advantages for teenage students.

For example, by scratch with percents rather than fractions, educators postpone the line of students having to comparing or dodge ratios with different denominators. This accepts children to concentrate on growing their own procedures for compare and calculation, instead of struggling to professional a complex direct of procedures that might seem inappropriate to them. A irregular advantage of this instructional approach is that by set out with percents, we allow children to make their first conversions among the different representations...
