Answers to Real World Examples of Number Sense

In our last blog, we provided some real-world problems for you to test your number sense skills. In this blog, we explain the number sense methods to solve those problems and provide their answers. The first problem we posed in the last blog was to figure out how to divide the total bill of $135 ($108 + 25% tip of $27) among 5 people. There are multiple ways of solving this problem using number sense. The first one of course is to break $135 into two parts of $100 and $35 and divide each part into 5. So, $100/5 = $20 and $35/5 = $7 and hence each person will pay $27. Another way to solve this problem is to realize that when you calculated 25% tip ($27) and added it to the bill amount of $108, the total amount became 125% of the original bill. Since there are five 25% in 125%, there are also five $27 in the total. So, each person will pay $27. Here are the answers to the other real-world examples in the previous blog.

• Discounts and Sales:
  • If an item is originally priced at $80 and is on sale for 30% off, what is the sale price?
  • Number Sense Method:
    • The quickest way to solve this problem is to first figure out 10% of $80 = $8.
    • Now, there are two ways to come up with the answer:
      • One is to realize that if an item is 30% off that means the item is selling at 70% of the original price. So, if 10% is $8, 70% would be $8 x 7 = $56.
      • The other way is to first calculate 30% and then subtract it from $80. So, if 10% is $8, 30% would be $8 x 3 = $24. Hence the selling price is $80 - $24 = $56.
  
  
• Time and Distance:
  • A train travels at an average speed of 50 miles per hour. How long will it take to travel 175 miles?
  • Number Sense Method:
    • The quickest way to solve this problem is to first figure out how many 50s are there in 175 miles. Since 3 x 50 is 150, we know there are 3 full 50s and the remainder is 25 miles. And 25 is half of 50. So, there are 3 and ½ 50s in 175.
    • So, if the average speed is 50 miles per hour, it will take 3 and ½ hours to travel 175 miles.
  
  
• Proportions and Scaling:
  • If a recipe calls for 2 cups of flour to make 24 cookies, how much flour is needed to make 42 cookies?
  • Number Sense Method:
    • The quickest way to solve this problem is to first figure out how many cookies can be made with 1 cup of flour. If 2 cups of flour will make 24 cookies, then 1 cup will make 12 cookies.
    • Now figure out how many 12s are there is 42. Since 12 x 3 = 36 we know there are 3 full 12s and the remainder is 6. And 6 is half of 12. So, there are 3 and ½ 12s in 42 cookies.
    • So, if 1 cup makes 12 cookies, 3 cups will make 36 cookies and 3 and ½ cups will make 42 cookies.
  
  
• Interest and Investments:
  • If you take a loan of $50,000 at an annual interest rate of 6%, how much interest will you pay in 3 years?
  • Number Sense Method:
    • The quickest way to solve this problem is to first figure out what is 1% of $50,000. 1% (which means 1 out of 100) of $50,000 is $500 (divide 50,000 by 100).
    • If 1% if $500, then 6% will be 6 x $500 = $3000.
    • Since the annual interest rate is 6%, you pay $3000 each year. Hence in 3 years you will pay $3000 x 3 = $9000.
  
  
• Measurement and Conversions:
  • You are 5.5 feet tall. How tall are you in inches?
  • Number Sense Method:
    • The quickest way to solve this problem is to first realize that there are 12 inches in a foot.
    • So, 5 feet will be 5 x 12 = 60 inches, and 0.5 feet (half a foot) is 6 inches.
    • Hence, 5.5 feet is 66 inches.

Real World Examples of Number Sense

What is Number Sense Number sense refers to an intuitive understanding of numbers and their relationships. It goes beyond memorizing procedures and formulas, allowing individuals to easily manipulate numbers, estimate quantities, and make sense of numerical information in various contexts. Real World Examples To understand the usefulness of number sense, let’s start with a simple real-world example. Imagine it’s Saturday evening and you and four of your friends just finished eating at a restaurant. The waiter handed the bill to you and the total on the bill is $108. You think the service was average and the tip should be 15%, but one of your friends thinks that the service was better than average, and the tip should be 20%. Moreover, another friend thinks the service was even better and thinks that you should leave a 25% tip. You want everyone to understand the difference in the amount for each of these tip percents. Your friends take out their phones to calculate the amount of tip and you tell them that you can do this in your head and give them the answers in under 30 seconds. Your friends are amazed and ask you how you did that. Here is what you tell them:

• 10% as a benchmark: First calculate 10% of the total amount as a benchmark. With number sense you understand that 10% just means 1/10th of the number and can be found by dividing the number by 10 (which is moving the decimal point one position to the left). So, 10% of $108 is $10.80.
• 15% tip: With number sense you understand that 15% is 10% plus 5% (which is half of 10%). To get the half of $10.80, you can separate $10 and 80 cents and get half of each and then add them back. Half of $10 is $5 and half of 80 cents is 40 cents, so half of $10.80 is $5.40. So, 15% of $108 is $10.80 + $5.40 = $16.20.
• 20% tip: With number sense you understand that 20% is double of 10%. To double $10.80, you can separate $10 and 80 cents and get the double of each and then add them back. Double of $10 is $20 and double of 80 cents is $1.60. So, 20% of $108 is $21.60.
• 25% tip: With number sense you understand that 25% is 20% plus 5%. So, 25% of $108 is $21.60 + $5.40 = $27.
• 25% tip alternate method: With number sense you also understand that 25% is 1/4th of the total amount. You can make the division easier by first breaking $108 into two parts: $100 + $8. Now you can divide each part by 4 and then add the results back. So, $100/4 = $25 and $8/4 = $2 and $25 + $2 = $27.

After discussing with your friends, you all decide to give 25% as tip and divide the total amount equally among the five of you. Use your number sense to figure out what each person will pay for the dinner. Answer to this question and all the answers from the next section will be posted in our next blog.

The associative property states that the value of mathematical expressions does not change when the order or grouping of the numbers used in the expression are moved around. This is true only when all the operations in the expression are either all additions or all multiplication. In other words, to add or multiply three or more numbers it is not necessary to add or multiply them in the same order they are given. Students can use this property and their understanding of numbers to make calculations easy by following the 3 simple steps below:

1. Group the numbers in such a way that the sum or the product of the numbers in the group is an easy number to add or multiply such as a ten or a multiple of ten.
2. Now find the sum or product of each group.
3. Finally add or multiply the results to get the answer.

For example, let’s say we need to find the sum of 9 + 78 + 91 + 22. Following the above 3 steps gives us:

1. Group the numbers for easy addition: (9 + 91) + (78 + 22).
2. Find the sum of each group: 100 + 100.
3. Then find the final sum: 100 + 100 = 200.

Let’s use another example to see how this will work for multiplying numbers. Let’s say we need to find the product of 4 x 358 x 25. Following the above 3 steps gives us:

1. Group the numbers for easy multiplication: (4 x 25) x 358.
2. Find the product of each group: 100 x 358.
3. Then find the final product: 358 x 100 = 35,800.

Although the above is a very simple concept, it clearly demonstrates how a deep understanding of simple mathematical properties and numbers can enable students to do quite complex calculations in their head. Developing strong number sense fosters a sense of confidence in students. They can approach mathematical problems with a sense of curiosity and exploration, knowing they have the tools to make sense of the numbers involved. This confidence spills over into other areas, encouraging critical thinking and problem-solving skills that are valuable in all walks of life.

How to Prepare for the UIL Mathematics Competition

As we discussed in our previous insight, fostering strong math skills in students is not just an academic pursuit; it's an investment in their future. To motivate students in developing strong math skills, the University Interscholastic League (UIL) created by the University of Texas at Austin conducts yearly Mathematics competitions for all Texas schools. Unlike the UIL Number Sense contest however, the UIL Mathematics contest is offered only at the middle school and high school levels. The middle school (grades 6 to 8) UIL mathematics contest is a 30-minute test, and it consists of 50 multiple choice problems. The high school (grades 9 to 12) UIL mathematics contest is a 40-minute test, and it consists of 60 multiple choice problems. While calculators are prohibited in the middle school UIL mathematics contests, students are allowed to use calculators in the high school contests. Since the UIL Mathematics contest covers a multitude of math concepts, students should devote an adequate amount of time to prepare for the contest. The amount of time each student should devote on preparing for the contest will depend on the student’s existing skill level. Students in lower grades will need to spend more time learning the concepts as some of the concepts would be entirely new for them. Students in higher grades would need to spend relatively less time to prepare. We recommend the following preparation times based on about 2 to 3 hours of preparation time per week:

Student Grade	Preparation Time
Grade 6 - 8	6 to 12 months
Grade 9 & 12	3 to 9 months

Students seriously preparing for the UIL Mathematics competition should follow these steps:

1. Devote the first 4 to 12 weeks (depending on existing skill level) entirely to review and internalize the concepts and tricks by working through the myQBook UIL mathematics concepts and practice problems. At this stage, don’t worry about taking the sample tests at all.
2. Make sure to do all the sample problems after learning each concept. If needed, repeat doing the practice problems after few days to fully internalize the concept and the problems that appear in the contest.
3. About 16 to 20 weeks before the contest date, start taking one test every week. Schedule the practice test approximately at the same time and day of the week that the actual context will take place. Make sure you will not be disturbed during the time of your practice test.
4. After taking the test, go back and review your completed test and understand what problems you got wrong and why. Also understand how you solved each problem and whether that was the fastest way to solve the problem. Compare your approach to the myQBook recommended method and understand the difference.
5. Throughout the following week review the concepts you didn’t score well on the test and practice sample problems.
6. On the week of the contest, try to relax and not study too much. Just review some of the concepts as you were doing in the previous weeks. Don’t take any more tests during the last week.

As you prepare for the contest, here are some other important points to keep in mind:

• Learn your multiplication tables – Middle school level at least till 25, and high school level till 30.
• Memorize the most commonly used squares, square roots, cubes, and cube roots listed in the myQBook UIL mathematics concepts.
• Understand and learn the Equivalent numbers (relationship between fractions, percents and decimal numbers) listed in the myQBook UIL mathematics concepts.
• Memorize the “Measures to Remember” in the myQBook concepts.
• While learning a concept think about why does the concept work and other applications of the same concept.
• Learn how to recognize various number patterns.
• Learn to break complex problems into smaller parts and then solve each part separately.

Demystifying Math: Why Number Sense is the Key to Unlocking Student Competence

Numbers are everywhere. From calculating tips to balancing budgets, mathematical fluency weaves its way through our lives. But for many students, math remains a mysterious land, filled with confusing symbols and frustrating equations. The key to mathematical fluency lies not in rote memorization or endless drills, but in developing a foundational skill: number sense. Number sense is more than just knowing your 123s. It's an intuitive understanding of what numbers represent, how they relate to each other, and how they can be manipulated to solve problems. It's the ability to estimate quickly, compare quantities with ease, and visualize numbers in different forms (fractions, decimals, etc.). Imagine the difference between memorizing the formula for area and effortlessly understanding that a 3x4 rectangle has the same area as a 6x2 rectangle – you're not just crunching numbers, you're utilizing your number sense.
Or imagine you want to buy 25 pieces of an item worth $48 each. With your number sense you intuitively understand that 25x48 is the same as 100x12 (100 = 25 x 4) and that your total cost would be $1200. This intuitive grasp of numbers forms the bedrock upon which all higher-level math is built. Without a strong number sense, students struggle to grasp complex concepts in algebra, geometry, and statistics. They become reliant on algorithms and formulas, unable to understand the underlying logic. This not only hinders their mathematical progress but also limits their problem-solving abilities in other areas of life.
Developing number sense takes time and dedicated practice. But the rewards are far-reaching:

• Enhanced problem-solving: With a firm grasp of numbers, students can approach problems creatively and strategically, breaking them down into manageable steps and choosing the most efficient solution.
• Increased confidence: Success in math fosters a sense of accomplishment and boosts confidence in other academic areas, too.
• Real-world application: Number sense equips students to deal with everyday situations involving money, measurement, budgeting, and more.
• Higher academic achievement: Studies have consistently shown a strong correlation between well-developed number sense and higher academic achievement in math and other subjects.

So, how can we cultivate number sense in students?

• Start early: Early childhood is a crucial time for building number sense through play, exploration, and concrete manipulatives.
• Make it engaging: Use games, puzzles, and real-world contexts to make math fun and relatable.
• Focus on understanding, not just memorization: Encourage students to explain their thinking and explore different ways to solve problems.
• Integrate technology: Use educational sites, apps and games to create engaging practice opportunities.
• collaboration: Collaborative learning allows students to share strategies and learn from each other.
• Encourage participation in friendly competitions: Participating in competitions, such as UIL Number Sense, motivates students to practice and develop strong number sense capabilities.
