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 consternation of reasonable-number operations Pages: 335-339 Traditional instruction in reasonable write 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 denary numbers, line up the decimals, then do your calculations. However, Remembering and by rights carrying out these relatively simple rules can be very difficult, however, when students do not have a good abstract introduction in the judicious numbers. Personally, when I was introduced to this new notion I was confused almost daily because my teacher anticipate me to bonny accept what she was saying and to memorize. Interestingly, this article presents computation abilities in sagacious numbers that were developed by fourth check students who participated in a resea rch 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 understand of the rational-number system. Students begin their investigations of rational numbers by learning more or less 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, edu cators dodge the problem of students having! to comparing or manipulate ratios with different denominators. This accepts children to decoct on growing their own procedures for comparison and calculation, instead of assay to master a complex set of procedures that might look foreign to them. A irregular advantage of this instructional antenna is that by beginning with percents, we allow children to make their first conversions among the different representations...
