Community Mathematics MCQ Quiz - Objective Question with Answer for Community Mathematics - Download Free PDF

Community mathematics refers to integrating real-life, local, and practical contexts into mathematics teaching. It emphasizes learning math through activities rooted in students' immediate environments, making the subject more accessible and meaningful.

Key Points

• Engaging students in community-based mathematics activities, such as calculating prices in a local market or measuring classroom items, helps them connect mathematical concepts to everyday life. This connection enhances motivation because students see the purpose of what they are learning.
• The reason supports the assertion well: when students perceive real-life relevance, mathematics becomes more meaningful and less abstract, boosting interest and engagement.

Hence, the correct answer is Both A and R are true and R is the correct explanation of A

Mathematics in the elementary classroom is most meaningful when connected to real-life contexts. Community mathematics involves engaging students with their surroundings, making learning authentic, relevant, and application-based. This approach helps students see the value of mathematics beyond the classroom.

Key Points

•  In this case, the teacher asks students to visit a local market, observe vegetable prices, and calculate costs. This task immerses learners in a real-world scenario, encouraging them to apply arithmetic skills in an everyday context.
• Such activities promote observation, estimation, addition, and practical thinking. It also bridges the gap between school learning and life outside the classroom, which is the essence of community mathematics.
• By making calculations using real data from their environment, children internalize concepts more deeply and meaningfully.

Hint

• Formal assessment refers to structured evaluation methods like tests and quizzes, which is not the case here.
• Rote learning of prices would involve memorization without understanding or application, which is not the intent of this task.
• Practicing abstract arithmetic means solving problems devoid of context or real-life connections, unlike this activity.

Hence, the correct answer is promoting community mathematics and real-world application.

Community mathematics involves connecting mathematical learning with students’ everyday experiences and local contexts. This approach helps students see the relevance of mathematics in their daily lives, making learning more meaningful and engaging. It also encourages students to apply mathematical concepts to solve practical problems they encounter.

Key Points

•  Using word problems that involve local market prices, familiar measurement units, and real-life situations from students’ surroundings creates a bridge between classroom learning and the community. It helps students understand concepts concretely and appreciate the usefulness of mathematics beyond textbooks.
• On the other hand, relying on international problems without adaptation, teaching only textbook problems unrelated to students’ context, or avoiding real-life problems limits students’ ability to relate to and apply mathematics in real-world situations.

Hence, the best approach for integrating community mathematics is to use word problems involving local market prices and measurement units familiar to students.

Higher-order questions are an essential part of effective mathematics instruction. They go beyond rote memorization and factual recall, requiring learners to apply, analyze, synthesize, and evaluate mathematical concepts.

Key Points

•  Higher-order questions encourage students to explain their thinking, justify their reasoning, and consider multiple ways to solve a problem. This approach promotes mathematical discourse and helps students make connections among concepts.
• By challenging learners to explore various strategies, these questions develop flexibility in problem-solving and a deeper grasp of mathematical ideas. In contrast, questions that focus solely on factual recall do not nurture these advanced thinking skills and thus do not align with the purpose of higher-order questioning.

Hint

•  The idea that higher-order questions are only useful for assessing factual recall is incorrect. Factual recall involves remembering and repeating known information, which falls under lower-order cognitive skills.
• Higher-order questions aim to assess and promote deeper understanding, which is far beyond simple memorization..

Hence, the correct answer is Only (a) is true.

Community mathematics refers to an approach that links mathematical concepts to the learners' immediate environment and daily life experiences. It helps students understand how mathematics is not just an abstract subject but a powerful tool for solving real-world problems. 

Key Points

• Statement A highlights that community mathematics connects mathematics to real-life problems. This is a core principle of the approach, as it draws on situations like shopping, construction, or measuring ingredients in cooking.
• Statement B emphasizes that such connections make learning more meaningful and contextual, helping students see the purpose and application of what they learn. These align directly intending to make mathematics more accessible and less abstract by rooting it in familiar situations.
• Statement C contradicts the idea of community mathematics. Isolating mathematics from a student’s social environment is the opposite of what this approach encourages. Instead of disconnecting students from their community, it aims to integrate local experiences, traditions, and tools into mathematical learning, making it a more engaging and inclusive subject.

Hence, the correct answer is A and B only.

In the above question, there is comparison addition is performed.

Given that:-

I have 6 pencils but Manish has more than 2 me

It means Manish have total pencil :- 6 + 2 = 8 pencil

Now we can easily understand their addition is performed and also compared with Manish pencils and my pencil.

Comparison Addition: In this method, we find the relation between two amounts by asking or telling how much more (or less) is one compared to the other.

Additional Information

• Comparison Subtraction: The difference between the two groups of numbers, namely, how much one is greater than the other, how much more is in one group than in the other. e.g., if Munna has 15 erasers and Munni 5, how many less does Munni have than Munna? 
• Takeaway: It is used for subtraction which means 'Remove', or  'Reduce' the group of words or numbers. E.g. How much is left if you take away 3 marbles from 5 marbles. In this way, the children learn to understand 'take away', and relate it to 'add'. 

Hence, it becomes clear that the given problem is comparison addition.

Inter-disciplinary approach not just the combination of two or more disciplines, but one discipline, which is facilitated by one or more disciplines.

Since in question it is asked about assessment strategy which would help in encouragement, hence we have to choose those points which can be categorized under formative assessment because formative assessment helps to improve performance and encourage to achieve goals.

Important Points

Assessment strategy to encourage interdisciplinary in Mathematics:

• Projects: While working on projects students get to know their weaknesses and strengths.
• Field trips: It will help the student assess their abilities and behaviors.

because it will enhance critical thinking, communication skill and it will help to analyze things at all the stages of life.

Additional Information

Also, Anecdotal records and Olympiad are important tools in mathematics and that can be used for assessment but not as an encouragement, as they are used for judging.

• Anecdotal records: A summary of an event in which a child or a group of children has taken part.
• Olympiad: An Examination conducted by various institution based on a different curriculum to compare the performance of the students with their peers.

Hence, we can conclude that projects and field tripscan be used as assessment strategy to encourage interdisciplinary in Mathematics.

Addition: When two collections of similar objects are put together, the total of them is called addition.

Properties of addition in natural and whole numbers:

• Closure property: Sum of two natural/whole numbers is also a natural/ whole number.
• Commutative Property: p + q = q + p where p and q are any two natural/ whole numbers.
• Associative property: (p + q) + r = p + (q + r) = p + q + r . This property provides the process for adding 3 (or more) natural/whole numbers.
• Additive Identity in Whole Numbers: In the set of whole numbers, 4 + 0 = 0 + 4 = 4. Similarly, p + 0 = 0 + p = p (where p is any whole number). Hence, 0 is called the additive identity of the whole numbers.

Mathematics is the study of geometrical figures, their co-relation, and their dependency on each other. It deals with quantity, measurement, and spatial relationships.

Key Points

• 'Elucid', a great Greek mathematician is the father of Demonstrative Geometry which is a branch of Mathematics deals with questions of different shape, size and figures.
• \He has proposed many methods in Geometry including intuitional, informal, observational, creative, intentional, constructive, experimental based on pure reasoning and geometrical truths. 

Hint

Hence, we conclude that Euclid is regarded as the father of Demonstrative Geometry.

The way to reach the students, help them achieve, solve classroom management issues, and create a healthy classroom environment is to build relationships with them. Building strong relationships with students can help them develop academically and socially.

A teacher can develop a good relationship with students in the following ways:

Important Points

Get to know the students: 

• Each student is unique and has unique personalities and needs, that's why it is important for a teacher to know them as individuals. Hence, a teacher should pay individual attention.

Show appropriate manners, and expect to receive the same:

• When students and teachers feel that they are respected and not treated unfairly, the relationships in the classroom will grow at a positive rate.
• Simple courtesy such as saying "thank you," "please" and "you're welcome" will show each of the students that the teacher respect and appreciate them, and it will encourage them to treat the teacher with the same courtesy.

Acknowledge the students: 

• Similar to the way professionals enjoy receiving recognition and praise for demonstrating hard work efforts, it is the same with the students.
• When students score an average high on a test, acknowledge them as a whole. If a few students received low markings, include them in the acknowledgment as well. It will encourage them to do better on the next test or assignment.

Create group activities: 

• Students love to have fun in the classroom regardless of age.
• Having group activities in the classroom every other week, give or take, is very beneficial to students. Not only do they give teachers a chance to connect with the students, but they also help build student-to-student relationships.

A teacher should be friendly with all, communicate well, love his students but all these can be achieved after building a good rapport with the students by paying individual attention.

A Geo-board is a mathematical instrument used to introduce basic concepts in plane geometry such as perimeter, area, and characteristics of triangles and other polygons. It consists of a physical board in which nails are placed at equal distances. Geoboards come in 5 by 5 pin arrays and 10 by 10 pin arrays. polygon figures can be made on a geoboard by stretching rubber bands across the nails.

Key Points Following concepts are helpful to understand by Geoboard:-

• Basic concepts and shapes in-plane geometry
• Properties of triangles and other polygons
• Property of similar figures
• Calculating Area of a polygon
• Calculating perimeter of polygon
• Help students having dysgraphia
• Used as a mathematical game that facilitates the understanding of students in playful learning.

Hence, the geoboard is an effective tool to teach geometrical shape and their properties.

Basic mathematics has been brought out to cater to the basic needs of the workers to understand the basics of mathematics and their application in day-to-day life. Certain basic aspects of mathematics, e.g. addition, subtraction, division, multiplication, percentage, profit, and loss, etc. are very important for everyone in daily life. 

Important Points

Perimeter: "The sum of lengths of all sides of a closed geometrical figure or the length of the boundary of a closed geometrical figure is called its perimeter."

The formulae for the perimeter of a rectangle and a square. The shape of the figure determines the perimeter. Every different shape has a different formula of the perimeter.

1) Square : a = side 

• Perimeter = 4 a

2) Rectangle : a = length b = breadth

• Perimeter = 2 (a + b)

Key Points

Area and perimeter are two different terms and have different formulas:

1) Square : a = side 

• Perimeter = 4 a
• Area= 2xa

2) Rectangle : a = length b = breadth

• Perimeter = 2 (a + b)
• Area= a x b

Same are but different perimeter: If two rectangles with the same area, and talking about the perimeter of those shapes. We found out that rectangles that have the same area don't necessarily have the same perimeter.

Hence, we can conclude that the shape of the figure determines the perimeter is the correct statement.

Students may have some facility with fractions, many of them appear not to have fully developed an understanding that fractions are numbers.

Using Paper Strips:

• To understand the concept of fractions at the primary level we use Paper Strips because children can easily learn to see concrete material and compare them.
• It is easy for children to understand from paper as children are very familiar with them.
• You need for this activity is a sheet of paper, some scissors, and a bit of patience when it comes to cutting the strips. And can easily explain  that \(\frac{1}{4}\) is less than \(\frac{1}{3}\).

LCM method:- It is difficult at the initial level because in this case, children are not able to compare any object.

Number chart:- It is used for counting numbers, and also useful for the learning table.

Dienes blocks:- It is a mathematical manipulating tool that helps children to learn basic mathematics like addition, subtraction, place value, counting, and simple multiplication.

Therefore, teaching children using paper strips is the most appropriate strategy to explain that \(\frac{1}{4}\) is less than \(\frac{1}{3}\).

Literal meaning of the verb ‘mathematize’ is ‘to reduce to or as if to mathematical formulas.’ In general, the term “mathematization” refers to the application of concepts, procedures and methods developed in mathematics to the objects of other disciplines or at least of other fields of knowledge. In the above situation:

• To arrange rectangular arrays, students need to have basic ideas about the properties of a rectangle.
• To arrange tiles students should have ideas of area, perimeter, and factors so that tiles can be adjusted on the required area according to size.
• Tiles are considered as 2D figures so volume has no role to play in this context.

Manipulatives are concrete objects that allow students to engage in active, hands-on exploration of a concept. For example- tangrams, tiles, rods, Diene's blocks, etc. The use of manipulation helps children to learn concepts through hands-on experience.

Key Points

• Importance of Manipulatives in the mathematics classroom
  • It helps the children connect mathematical ideas and symbols to physical objects, thus promoting better understanding.
  • It provides support in dealing with a subject that can be difficult and confusing and help students build confidence by giving them a way to test and confirm their reasoning.
  • Manipulative is imperative for exploration and experimentation with math ideas as students develop meaning.
  • It facilitates students understanding of mathematical concepts and links them to representation and abstract ideas.
  • It makes learning math interesting and enjoyable and also motivates children to learn.

Hence, we conclude that the use of manipulation is integral to the teaching-learning of mathematics at the primary level because it helps the learner to comprehend mathematical concepts.
