Direction: Read the following passage and answer the question that follows:

There are several key difficulties surrounding the topic of percentages. Research has shown that there has been one difficulty which is more common than others; the meaning of the terms ‘of’ and ‘out of’. Hansen (2011) states that both terms represent an operator which needs explaining. Teachers need to address these before the topic is introduced to stop any confusion. ‘Of’ represents the multiplication operator, for example: 60% of 70 means 0.6 multiplied by 70; ‘out of’ represents the division operator, for example 30 out of 50 means 30 divided by 50. The teaching of these terms needs to be clear prior to teaching, so that children are confident in what these terms represent.
Killen and Hindhaugh (2018) believe that once children understand that 1/10 is equal to 10% they will be able to use their knowledge of fractions to determine other multiples of 10. For example; Find 40% of 200. If children are aware that 10% is 20, then it will become obvious to them that 40% must be 80. This method enlightens many other practical ways to find other percentages of a quantity. Once children know 10%, they may also start finding half percent’s, such as; 5% or 25%. However, Killen and Hindhaugh (2018) state that a difficulty could occur when they are asking for a percentage of a quantity. If children are being asked to find the percentage, they may believe that the answer is always in percent. For example; find 60% of £480. Children may be capable of calculating the answer of 288 but instead of writing down £288, they may write down 288%. Teachers will need to explain this issue and address to children that once calculating the answer, it must be in the same units as the given quantity.
Hansen also comments that the key to succession in the understanding of percentages is the relationship and understanding the children have with fractions and decimals. For example: they should be aware that 50% is equivalent to ½ and 0.5, and 25% is equivalent to ¼ and 0.25. Teaching these topics in isolation of each other should be strictly avoided as this may destroy a child’s deep mathematical understanding. Killen and Hindhaugh agree with this as they noted that children need to continually link decimals, fractions and percentages to their knowledge of the number system and operations that they are familiar with. Reys, et al (2010) believes however that percentages are more closely linked with ratios and proportions in mathematics and how important it is for teachers to teach these other topics to a high level. This is to later reduce the amount of errors a child has over percentages. However, these theorists also agree that understanding percentages requires no more new skills or concepts beyond those used in identifying fractions, decimals, ratios and proportions. Reys, et al states that an effective way of starting these topics is to explore children’s basic knowledge of what percentage means to them.
Barmby et al noted that a misconception occurs whenever a learner’s outlook of a task does not connect to the accepted meaning of the overall concept. Ryan and Williams state that it is more damaging for children to have misconceptions of mathematical concepts than difficulties calculating them. Killen and Hindhaugh begin to talk how the use of rules and recipes are commonly used more so by teachers that are not fully confident with percentages. The main point of the argument is that if children are taught these rules linked to percentages, misconceptions can occur. This could be caused if the child forgets or misapplies the rule to their working out.

This method is not the most reliable for children but can be a quick alternative for teachers to teach their class, if they are not fully confident in the topic themselves. This links to one of the most common misconceptions in the primary classroom. Killen and Hindhaugh state that it is the teacher’s responsibility for their children’s successes in that subject area. If the teaching is effective, then the child will become more confident and develop more links revolving around the topic of percentages. This will result in the child having a high level of understanding. However, if the teaching is not up to standard the child may lose confidence in themselves and end up being confused with the simplest of questions.
Q. Which one of the following is not a valid inference from the passage?
  • a)
    A strong understanding of fractions, decimals, ratios, and proportions is necessary for mastering percentages.
  • b)
    Misconceptions in mathematical concepts can be more damaging for children than difficulties in calculations.
  • c)
    Teaching percentages in isolation can improve a child's mathematical understanding.
  • d)
    Teachers who are not confident in teaching percentages may rely on rules and recipes, which can lead to misconceptions.
Correct answer is option 'C'. Can you explain this answer?

Using the BANE theory, we can eliminate options as follows:
(a) A strong understanding of fractions, decimals, ratios, and proportions is necessary for mastering percentages.
This statement can be inferred from the passage as it discusses the importance of linking decimals, fractions, and percentages to children's knowledge of the number system and operations. It also mentions that percentages are closely linked with ratios and proportions in mathematics. Thus, this option is neither Broad, Alien, Narrow, nor Extreme.
(b) Misconceptions in mathematical concepts can be more damaging for children than difficulties in calculations.
This statement can be inferred from the passage as Ryan and Williams (2007) are quoted, stating that it is more damaging for children to have misconceptions of mathematical concepts than difficulties calculating them. Thus, this option is neither Broad, Alien, Narrow, nor Extreme.
(c) Teaching percentages in isolation can improve a child's mathematical understanding.
This statement is Alien and Extreme compared to the passage. The passage explicitly mentions that teaching these topics in isolation should be strictly avoided as it may destroy a child's deep mathematical understanding. Hence, this option is not a valid inference from the passage.
(d) Teachers who are not confident in teaching percentages may rely on rules and recipes, which can lead to misconceptions.
This statement can be inferred from the passage as it discusses how teachers who are not fully confident with percentages may use rules and recipes, which can lead to misconceptions if the child forgets or misapplies the rule. Thus, this option is neither Broad, Alien, Narrow, nor Extreme.
Answer: (c) Teaching percentages in isolation can improve a child's mathematical understanding.
Option C is not a valid inference from the passage, as it contradicts the idea that teaching percentages, fractions, and decimals in isolation should be avoided. The passage emphasizes the importance of linking these topics to develop a deep mathematical understanding in children.

On the basis of the information in the passage, all of the following are potential problems children might face when learning percentages EXCEPT that they

Directions: Read the following passage carefully and answer the questions that follow.Bill Gates is a lot luckier than you might realise. He may be a very talented man who worked his way up from geek to the top spot on the list of the world's richest people. But his extreme success perhaps tells us more about the importance of circumstances beyond his control than it does about how skill and perseverance are rewarded.We often fall for the idea that the exceptional performers are the most skilled or talented. But this is flawed. Exceptional performances tend to occur in exceptional circumstances. Top performers are often the luckiest people, who have benefited from being at the right place and right time. They are what we call outliers, whose performances may be examples set apart from the system that everyone else works within.Many treat Gates, and other highly successful people like him, as deserving of huge attention and reward, as people from whom we could learn a lot about how to succeed. But assuming life's "winners" got there from performance alone is likely to lead to disappointment. Even if you could imitate everything Gates did, you would not be able to replicate his initial good fortune.For example, Gates's upper-class background and private education enabled him to gain extra programming experience when less than 0.01% of his generation then had access to computers. His mother's social connection with IBM's chairman enabled him to gain a contract from the then-leading PC company that was crucial for establishing his software empire.This is important because most customers who used IBM computers were forced to learn how to use Microsoft's software that came along with it. This created an inertia in Microsoft's favour. The next software these customers chose was more likely to be Microsoft's, not because their software was necessarily the best, but because most people were too busy to learn how to use anything else.Microsoft's success and market share may differ from the rest by several orders of magnitude, but the difference was really enabled by Gate's early fortune, reinforced by a strong success-breeds-success dynamic. Of course, Gates's talent and effort played important roles in the extreme success of Microsoft. But that's not enough for creating such an outlier. Talent and effort are likely to be less important than circumstances in the sense that he could not have been so successful without the latter.One might argue that many exceptional performers still gained their exceptional skill through hard work, exceptional motivation or "grit", so they do not deserve to receive lower reward and praise. Some have even suggested that there is a magic number for greatness, a ten-year or 10,000-hour rule. Many professionals and experts did acquire their exceptional skill through persistent, deliberate practices. In fact, Gates' 10,000 hours learning computer programming as a teenager has been highlighted as one of the reasons for his success.But detailed analyses of the case studies of experts often suggest that certain situational factors beyond the control of these exceptional performers also play an important role. For example, three national champions in table tennis came from the same street in a small suburb of one town in England.This wasn't a coincidence or because there was nothing else to do but practise ping pong. It turns out that a famous table tennis coach, Peter Charters, happened to retire in this particular suburb. Many kids who lived on the same street as the retired coach were attracted to this sport because of him and three of them, after following the "10,000-hour rule", performed exceptionally well, including winning the national championship.Their talent and efforts were, of course, essential for realising their exceptional performances. But without their early luck (having a reliable, high-quality coach and supportive families), simply practicing 10,000 hours without adequate feedback wouldn't likely lead a randomly picked child to become a national champion.We could also imagine a child with superior talent in table tennis suffering from early bad luck, such as not having a capable coach or being in a country where being an athlete was not considered to be a promising career. Then they might never have a chance to realise their potential. The implication is that the more exceptional a performance is, the fewer meaningful, applicable lessons we can actually learn from the "winner".When it comes to moderate performance, it seems much more likely that our intuition about success is correct. Conventional wisdom, such as "the harder I work the luckier I get" or "chance favours the prepared mind", makes perfect sense when talking about someone moving from poor to good performance. Going from good to great, however, is a different story.Being in the right place (succeeding in a context where early outcome has an enduring impact) at the right time (having early luck) can be so important that it overwhelms merits. With this in mind there's a good case that we shouldn't just reward or imitate life's winners and expect to have similar success. But there is a case that the winners should consider imitating the likes of Gates (who became a philanthropist) or Warren Buffett (who argues that richer Americans should pay higher taxes) who have chosen to use their wealth and success to do good things. The winners who appreciate their luck and do not take it all deserve more of our respect.Q. It can be understood that the main purpose of the author in the third paragraph is to

The teaching of these terms needs to be clear prior to teaching, so that children are confident in what these terms represent.Killen and Hindhaugh (2018) believe that once children understand that 1/10 is equal to 10% they will be able to use their knowledge of fractions to determine other multiples of 10. For example; Find 40% of 200. If children are aware that 10% is 20, then it will become obvious to them that 40% must be 80. This method enlightens many other practical ways to find other percentages of a quantity. Once children know 10%, they may also start finding half percent’s, such as; 5% or 25%. However, Killen and Hindhaugh (2018) state that a difficulty could occur when they are asking for a percentage of a quantity. If children are being asked to find the percentage, they may believe that the answer is always in percent. For example; find 60% of £480. Children may be capable of calculating the answer of 288 but instead of writing down £288, they may write down 288%. Teachers will need to explain this issue and address to children that once calculating the answer, it must be in the same units as the given quantity.Hansen also comments that the key to succession in the understanding of percentages is the relationship and understanding the children have with fractions and decimals. For example: they should be aware that 50% is equivalent to ½ and 0.5, and 25% is equivalent to ¼ and 0.25. Teaching these topics in isolation of each other should be strictly avoided as this may destroy a child’s deep mathematical understanding. Killen and Hindhaugh agree with this as they noted that children need to continually link decimals, fractions and percentages to their knowledge of the number system and operations that they are familiar with. Reys, et al (2010) believes however that percentages are more closely linked with ratios and proportions in mathematics and how important it is for teachers to teach these other topics to a high level. This is to later reduce the amount of errors a child has over percentages. However, these theorists also agree that understanding percentages requires no more new skills or concepts beyond those used in identifying fractions, decimals, ratios and proportions. Reys, et al states that an effective way of starting these topics is to explore children’s basic knowledge of what percentage means to them.Barmby et al noted that a misconception occurs whenever a learner’s outlook of a task does not connect to the accepted meaning of the overall concept. Ryan and Williams state that it is more damaging for children to have misconceptions of mathematical concepts than difficulties calculating them. Killen and Hindhaugh begin to talk how the use of rules and recipes are commonly used more so by teachers that are not fully confident with percentages. The main point of the argument is that if children are taught these rules linked to percentages, misconceptions can occur. This could be caused if the child forgets or misapplies the rule to their working out.This method is not the most reliable for children but can be a quick alternative for teachers to teach their class, if they are not fully confident in the topic themselves. This links to one of the most common misconceptions in the primary classroom. Killen and Hindhaugh state that it is the teacher’s responsibility for their children’s successes in that subject area. If the teaching is effective, then the child will become more confident and develop more links revolving around the topic of percentages. This will result in the child having a high level of understanding. However, if the teaching is not up to standard the child may lose confidence in themselves and end up being confused with the simplest of questions.Q. Which one of the following is not a valid inference from the passage?a)A strong understanding of fractions, decimals, ratios, and proportions is necessary for mastering percentages.b)Misconceptions in mathematical concepts can be more damaging for children than difficulties in calculations.c)Teaching percentages in isolation can improve a childs mathematical understanding.d)Teachers who are not confident in teaching percentages may rely on rules and recipes, which can lead to misconceptions.Correct answer is option 'C'.

Teachers will need to explain this issue and address to children that once calculating the answer, it must be in the same units as the given quantity.Hansen also comments that the key to succession in the understanding of percentages is the relationship and understanding the children have with fractions and decimals. For example: they should be aware that 50% is equivalent to ½ and 0.5, and 25% is equivalent to ¼ and 0.25. Teaching these topics in isolation of each other should be strictly avoided as this may destroy a child’s deep mathematical understanding. Killen and Hindhaugh agree with this as they noted that children need to continually link decimals, fractions and percentages to their knowledge of the number system and operations that they are familiar with. Reys, et al (2010) believes however that percentages are more closely linked with ratios and proportions in mathematics and how important it is for teachers to teach these other topics to a high level. This is to later reduce the amount of errors a child has over percentages. However, these theorists also agree that understanding percentages requires no more new skills or concepts beyond those used in identifying fractions, decimals, ratios and proportions. Reys, et al states that an effective way of starting these topics is to explore children’s basic knowledge of what percentage means to them.Barmby et al noted that a misconception occurs whenever a learner’s outlook of a task does not connect to the accepted meaning of the overall concept. Ryan and Williams state that it is more damaging for children to have misconceptions of mathematical concepts than difficulties calculating them. Killen and Hindhaugh begin to talk how the use of rules and recipes are commonly used more so by teachers that are not fully confident with percentages. The main point of the argument is that if children are taught these rules linked to percentages, misconceptions can occur. This could be caused if the child forgets or misapplies the rule to their working out.This method is not the most reliable for children but can be a quick alternative for teachers to teach their class, if they are not fully confident in the topic themselves. This links to one of the most common misconceptions in the primary classroom. Killen and Hindhaugh state that it is the teacher’s responsibility for their children’s successes in that subject area. If the teaching is effective, then the child will become more confident and develop more links revolving around the topic of percentages. This will result in the child having a high level of understanding. However, if the teaching is not up to standard the child may lose confidence in themselves and end up being confused with the simplest of questions.Q. Which one of the following is not a valid inference from the passage?a)A strong understanding of fractions, decimals, ratios, and proportions is necessary for mastering percentages.b)Misconceptions in mathematical concepts can be more damaging for children than difficulties in calculations.c)Teaching percentages in isolation can improve a childs mathematical understanding.d)Teachers who are not confident in teaching percentages may rely on rules and recipes, which can lead to misconceptions.Correct answer is option 'C'. Can you explain this answer? theory, EduRev gives you an ample number of questions to practice Direction: Read the following passage and answer the question that follows:There are several key difficulties surrounding the topic of percentages. Research has shown that there has been one difficulty which is more common than others; the meaning of the terms ‘of’ and ‘out of’. Hansen (2011) states that both terms represent an operator which needs explaining. Teachers need to address these before the topic is introduced to stop any confusion. ‘Of’ represents the multiplication operator, for example: 60% of 70 means 0.6 multiplied by 70; ‘out of’ represents the division operator, for example 30 out of 50 means 30 divided by 50. The teaching of these terms needs to be clear prior to teaching, so that children are confident in what these terms represent.Killen and Hindhaugh (2018) believe that once children understand that 1/10 is equal to 10% they will be able to use their knowledge of fractions to determine other multiples of 10. For example; Find 40% of 200. If children are aware that 10% is 20, then it will become obvious to them that 40% must be 80. This method enlightens many other practical ways to find other percentages of a quantity. Once children know 10%, they may also start finding half percent’s, such as; 5% or 25%. However, Killen and Hindhaugh (2018) state that a difficulty could occur when they are asking for a percentage of a quantity. If children are being asked to find the percentage, they may believe that the answer is always in percent. For example; find 60% of £480. Children may be capable of calculating the answer of 288 but instead of writing down £288, they may write down 288%. Teachers will need to explain this issue and address to children that once calculating the answer, it must be in the same units as the given quantity.Hansen also comments that the key to succession in the understanding of percentages is the relationship and understanding the children have with fractions and decimals.
