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 alarm of reasonable-number operations Pages: 335-339 Traditional instruction in reasonable verse focuses on rules and memorization. Teachers often give students instructions such as, To tote bag up fractions, first find a common denominator, then(prenominal) 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 very(prenominal) difficult, however, when students do not have a good conceptual 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 lucid numbers that were developed by fourth graze students who p articipated 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 judgement of the rational-number system. Students begin their investigations of rational numbers by learning nigh 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 rat her than fractions, educators protract the ! problem of students having to comparing or manipulate ratios with dissimilar denominators. This accepts children to distil on growing their own procedures for comparison and calculation, instead of seek to master a complex set of procedures that might see foreign to them. A irregular advantage of this instructional burn up is that by beginning with percents, we allow children to make their first conversions among the different representations...
