Equivalence Essay Example | Topics and Well Written Essays - 750 words

Equivalence - Essay Example 2. The concept of "how", accompanies the concept of "why. The "how" something works is teaching the mechanical pieces of the lesson. This is often boring to the child and not very well received, but if combined with an insightful "why" lesson you will have a far simpler task ahead of you. Each child will process the information differently, so you may need to alternate the focus of lessons by using one period going over the how and another going over the why and supplementing with practice sheets. 3. Clarifying the term "Equivalent" and Finding A Common Demoninator: Perhaps the most crucial part of teaching equivalence in fractions is teaching the children how to find a common denominator. The term itself is intimidating, but the task is not impossible. The best way to teach children how to find a common denominator is to use manipulatives. The fact that Students' have misconstrued the equal sign is a topic that has been researched for more than thirty years (Weaver, 1971,1973). It might be beneficial to start off with discussing with the class what the term "equivalent" means to them. At least by doing so we can gage where our students are from a terminology standpoint. This would be beneficial if applied the terms numerator and denominator as well. Because we are dealing with rather large terms it helps to have visual aids. This is where the use of manipulatives comes in handy. Manipulatives are an essential teaching tool which allow children to learn visually. B. The Concept of Finding Equivalent Fractions Using Manipulatives. The problem with textbooks and workbooks is that often the children are distracted by the instructions and fail to use the visual aid. Children move from addition and subtraction (concepts that they have likely been using well before their formal education began on the topic) and are suddenly thrust into an area which is completely foreign. Cursory review of math text and exercise books reveals a great deal of "words" which I think are intimidating. Yes there are pretty pictures with bunnies, pies, balls and whatnot. Yet children still fail to become engaged. Why not turn the lesson into a visual demonstration that you and the children can enjoy Moreover, by watching the children actively participate, we as teachers are able to assess their true comprehension. This is the advantage of using manipulatives. Additionally, it is a wonderful way to insure complete class participation. C. Steps I would teach students in finding Equivalent fractions. I have found that children of all ages are very interested in detective work. There is a sense of power and self confidence that comes with solving a mystery. Television is replete with various shows that show crime scene investigations along with the science behind it. Moreover, both girls and boys seem to have an equal interest in the field. I would suggest to my students that we are CSI detectives. I would suggest that the first thing that we might want to do is to ID (identify) our fraction. Included with that identification would be all of the alias our fraction might use to evade our

Maritime technology Essay Example | Topics and Well Written Essays - 2000 words

Maritime technology - Essay Example Developments in shipbuilding technology; and coming up with new navigation aids have opened up the route hopefully for year-round navigation (Ragner 2000a). This essay seeks to examine the technical; navigation and operational issues in the realization of an effective Northern Sea Route in Navigation of Merchant ships. Year-round navigation on the NSR means massive economic and commercial benefits to the international community, as well as invigorates Russian goods transport; thus, availing more natural resources from the Russian Arctic on the world market (ScanEx 2010). Research efforts in the NSR have mainly focused on four themes incorporating; the natural circumstances in the Arctic and ice navigation technology; the eventual effects of opening the NSR upon the natural, biological and social environments in the Arctic regions; the potential of NSR economically and the political and legal backgrounds linked to the NSR opening (Brigham 2000). The following section will discuss the technical, navigational and operational activities undertaken by key players in the maritime industry in the realization of successful sailing in the arctic region. With the problem of ice in the arctic region, technical issues are core to the achievement of effective navigation in the sea. Invention of new vessels of high technology is crucial to counter the problem of ice in the Arctic region. Of late there has been the introduction of the first seismic vessel on the NSR; it has a design that saves time, fuel and cost (Oil & Gas Eurasia, 2011). This is a considerable achievement in the sense that, the aim of any organization is to sustainably reduce the cost of operation while at the same time, taking minimum time possible to accomplish any undertaking and achieve the intended target. According to Oil and Gas Eurasia (2011), the vessel by the name Polarcus Alima from the
