Rounding with decimals to the nearest tenth Essay

Rounding with decimals to the nearest tenth - Essay Example This information should suffice for most students who have a solid grounding in the prerequisites. However, weaker students would require not only a good revision of the place value system, rounding whole numbers, recognizing decimal numbers etc. beforehand but could also be aided by a visual representation for rounding numbers, and if necessary a flowchart of the procedure given above (to prevent procedural errors). For the former, the number line is ideal. An example is given below. The similarity with rounding whole numbers should be stressed. They are not really learning anything new. All they need to be careful with now is the decimal point. Thinking along these lines should be reinforced in demonstrating the rounding procedure using the number line (3 examples are given): Five situations are the most likely occasions of problems for students learning to grasp the concept of rounding to the nearest tenth digit. This is given in order of increasing difficulty based on my own experience of teaching children. 1. What to do when the digit in the hundredths place is 0 (zero). Zero does confuse many students. In this case the student should be reminded that (due to its position in this particular case) it holds no value and it is similar to the situation when the digit in this place is either 1, 2, 3 or 4 i.e. we simply truncate the number at the tenths position e.g. 1.60 would become 1.6 similar to 1.63 also becoming 1.6. 2. What to do when the digit in the hundredths place is 5 (five) – perceived as a ‘halfway’ or ‘middle’ point. In this case, the teacher needs to remind the rule that we round up when this digit is a 5 and it is similar to the situation when the digit in this place is either 6, 7, 8 or 9 i.e. we simply increase the number in the tenths position by 1 and leave out the 5 (the hundredth digit) e.g. 1.65 would become 1.7 similar to 1.67

Film History - Term Paper Example The movie is composed of mostly two hours of the North Vietnamese soldiers charging towards the American troops, mortar rounds that were meant to disseminate the American lines, as well as the American jets mowing down the fields of the Vietnamese soldiers. One of the things that have been effectively portrayed in the movie is to stage all the actions that took place in away that understandable and comprehensible. The larger part of the film adheres to the actual events that took place during the historical battle. In the movie, it can be seen that the battles were taking place in several open fields. Even though the battles historically took place within the rough terrain of the Vietnam, the scenes of the battle were in denser bushes. The terrain in Vietnam is naturally dense. A larger part of the Vietnam is covered with dense hence making the visibility limited and consequently leaving limited bald spots within the Vietnam terrain. The film shows several scenes that were shot in the open fields that had little vegetation and whenever there is appearance of vegetation, it is the wrong type when compared with that in Vietnam. Indeed, the film shows vegetations that resembles those in Tahoe or to some extent some of the deciduous forest and not Vietnam. Nonetheless, a critical look at the movie indicates that the only thing that could have been more accurate regarding its setting was the hilly terrain (Schwarzbaum Web). Overall it should be noted that the movie did not perform well in the portrayal of the terrain with accuracy it deserved. The fighting that is portrayed in the movie is mainly composed of the bombs and firearms. This portraying is pretty much the reality of what took place at the ground that has slightly differed from how it actually took place. This can be partly attributed to the mistake witnessed in the scenery but understandably this could have been difficult to shoot in case
