Computational thinking is a fundamental problem-solving approach often used in mathematics and computer science. It involves breaking down complex problems into manageable parts, identifying patterns, abstracting general principles, and creating step-by-step algorithms. These skills are essential for analytical reasoning and logical thinking.

Key Points

•  Memorization is not a component of computational thinking. While remembering certain facts or formulas may aid in solving problems, computational thinking is more about process and strategy than rote recall.
• It focuses on understanding how to solve a problem by developing and applying logical steps, not simply remembering procedures without comprehension.

Hint

• Decomposition is a key element where a problem is broken into smaller, more manageable parts.
• Pattern recognition helps in identifying similarities and trends which can simplify solutions.
• Algorithmic thinking involves creating a sequence of logical steps to solve a problem effectively.

Hence, the correct answer is memorization.

Mathematics holds various values that reflect its importance in different areas of life, such as social development, aesthetic appreciation, practical use, and enjoyment.

Key Points

• Using mathematics to plan a household budget, calculate discounts while shopping, or manage travel expenses demonstrates its practical and functional nature, which describes utilitarian value.
• In such cases, math is directly applied to solve real-world problems and make informed decisions.
• This use of mathematics to perform everyday tasks that require logical thinking, number sense, and problem-solving skills shows how essential it is for managing daily life efficiently.
• It helps individuals become self-reliant and economically responsible, reflecting the practical or utilitarian aspect of mathematics in action.
•  

Hint

•  The social value of mathematics refers more to how math contributes to societal development and helps address community or national-level challenges, such as planning infrastructure or interpreting data for policies.
• The aesthetic value of mathematics is seen in the beauty, elegance, and patterns found in mathematical structures, which often appeal to one’s sense of harmony or symmetry.
• The recreational value refers to the enjoyment and fun derived from puzzles, games, and mathematical challenges that entertain while promoting logical thinking.

Hence, the correct answer is Utilitarian.

When we use numbers in an ordinal sense, we are indicating position or order in a sequence. Ordinal numbers answer the question "Which one?" and describe the rank or position of an item.

Key Points

•  In the given options, the sentence "She finished in th place in the competition" uses the number 7 in an ordinal sense, as it describes her position in the competition.

The other options represent the number 7 in a cardinal sense, indicating quantity:

• "There were 7 chairs in the room" refers to the number of chairs.
• "7 is the number of times she has called" refers to the frequency of an event.
• "The group consisted of 7 members" refers to the count of group members.

Thus, the sentence "She finished in 7th place in the competition" represents the number 7 used in an ordinal sense.

Arranging numbers from largest to smallest means organizing them in descending order. When we apply a mathematical operation like multiplying each number by a negative value, it can reverse their positions on the number line because negative multiplication flips the sign and the direction.

Key PointsRiya's list is: 20, 15, 10, 4 (from largest to smallest).
Multiplying each by −3 gives:
-20 × (−3) = −60
-15 × (−3) = −45
-10 × (−3) = −30
-4 × (−3) = −12

Now the new list becomes: −60, −45, −30, −12, which, in order from smallest to largest, is the opposite of the original descending order.
So, the list now follows an ascending order, or from smallest to largest.

Hint

• Option 1 is incorrect because multiplying by a negative number reverses the order, it doesn't stay the same.
• Option 3 is incorrect since the numerical positions do change based on the result of the multiplication.
• Option 4 is incorrect because the number of elements in the list remains the same—just their values change.

Mathematics is an essential discipline with applications across numerous fields and professions. The value of mathematics extends beyond its academic pursuit and is seen in its practical uses in everyday life, career opportunities, and societal functions.

Key Points

• The statement focuses on how mathematics is used directly or indirectly in various professions such as accountancy, banking, shop-keeping, and tailoring.
• This reflects the utilitarian value of mathematics, meaning its usefulness in real-world applications and practical problem-solving.
• The primary purpose of mathematics in these fields is not theoretical but serves to facilitate day-to-day tasks and decision-making processes.

Hint

• Disciplinary value refers to mathematics as a formal discipline with its own principles, theories, and methods. It focuses on the internal structure and beauty of the subject rather than its practical application.
• Cultural value would refer to how mathematics influences or is influenced by cultural practices, traditions, or intellectual history, not its use in professions.
• Professional value implies how mathematics directly impacts specific professions but doesn’t capture the broader, general practical application across a variety of jobs as the utilitarian value does.

Hence, the correct answer is Utilitarian value of Mathematics.

Mathematics is not just the study of numbers and statistical data but also studies the different types of shapes, figures, and patterns.

• In early schooling, the learners began to learn about shapes and try to differentiate various shapes from each other.
• The Van Hiele's levels originated in 1957 given by Pierre Van Hiele and his wife from the Utrecht University in the Netherlands.
• It helped in shaping the curriculum throughout the world that especially influenced the learning of geometry at a large level.
• It provides an insight to the teacher about how the students learn geometry at different levels. It describes how the students learn at each level and pass to another level.

Key Points

The Van Hiele levels are described below:

Hence, it is concluded that Rohit is at the level 2 (Relationships) stage of Van Hiele's visual thinking.

Critical Thinking: The ability to apply reasoning and logic to new or unfamiliar situations, ideas, and opinions. It refers to the process of judging or analysing facts, events, etc. It requires proper analysis, evaluation, inference and explanation.

• Thinking critically involves seeing and observing things in an open-minded way and examining an idea or concept in a way to form as many angles as possible.
• Reasoning tasks promote critical and creative thinking in mathematics.

Open-Ended questions: Open-ended questions are the questions which can't be answered in yes or no, rather requires a detailed answer with proper explanation. These are a useful tool for primary teachers to help students to discover new ideas and develop critical thinking.

For example:- Following questions are open ended:-

• Evaluate 72 × 73 in three different ways and compare the result.
• Formulate any two situation to represent the equation 7x + 3 = 24.
• A students calculated the volume of a right circular cylinder of radius 3.5 cm and height 10 cm as 38.5 cm3. What did she go wrong?

Close Ended Questions: These allow a learner to choose one answer from a limited list of possible answers.

For example:- Calculate the volume of a right circular cylinder of radius 3.5 cm and height 10 cm.

Here calculating the volume of a right circular cylinder will not develop critical thinking among students, as it is just concern with putting up values into already deduced formula.

Ways to Develope Critical Thinking in a Child:

• Begin with a question
• Create a foundation
• Consult the classics
• Use information fluency
• Utilize peer groups
• Try one sentence at a time
• Problem-solving
• Return to role-playing

Hence, it becomes clear that the tasks like calculating the volume of a right circular cylinder will not develop critical thinking among students.

Word problems in mathematics are those questions that are given in the form of statements, which, after comprehension, are solved using mathematical operations. Word problems help to develop the ability to convert real-life problems into mathematical problems and find out a solution.

Key Points

•  It is noted that when the child has faced a problem in solving a word problem, then the child is having a problem in understanding number operations.
• He is having difficulty understanding the concept of numbers like addition, subtraction, multiplication, or division.
• So if the child cannot understand the word problem statement then he lacks conceptual understanding related to the number operations that are not clear to him.
• For example, Rajan is facing problems while solving a word problem and asks “Should I add or subtract”, “Should I multiply or divide ?”. It is showing that he is unable to interpret the problem and is unaware of the next step to be taken.
• The mathematics teacher should teach him using different methods to help him in understanding complex mathematical word problems.

Hint

• A child shouldn't face problems in comprehending the language of all questions and if it is so then it means that the child is facing problem in other aspects of the question.
• Here, it shows Rajan has a problem of understanding number operations. Which is why after going through a word problem he usually asks “Should I add or subtract”, “Should I multiply or divide ?” 

Hence, we can conclude that Rajan usually asks “Should I add or subtract”, “Should I multiply or divide ?”.Such question suggest Rajan lacks understanding of number operations.

Zoltan Paul Dienes is one of the earliest representatives of both the embodied conception of learning and teaching mathematics. Zoltan Dienes, Hungarian mathematician, and education psychologist believed that mathematical structures could be effectively taught to primary-aged children through the use of manipulative, games and stories.

Key PointsZoltan's theory has four principles that he believes apply to learning mathematics.

• Dynamic Principle – Learning is an active process that requires opportunities to be provided for students to interact. He states that to be able to understand a concept, there are three essential steps – the play stage, the structure stage, and finally the practice stage.
• The final Perceptual principle: It states that different kinds of teaching materials should be used to teach the same concept or idea.
• The Mathematical Variability principle:  It states that when knowledge is imparted, all other irrelevant facts should be systematically varied whilst keeping the relevant variables the same. For example, in teaching the definition of what a triangle is, the teacher should change the size, the angles, and the orientation of the triangle so that the students understand that it is three sides and three angles that define a triangle.
• Constructivity principle – Students need to construct their knowledge before analytical activity.

Thus, the correct sequence of Zoltan's theory is Perceptual Variability Principle, Mathematical Variability Principle, and Constructivity Principle.

Geometry is a branch of mathematics that studies the sizes, shapes, positions angles and dimensions of things. Flat shapes like squares, circles, and triangles are a part of flat geometry and are called 2D shapes. These shapes have only 2 dimensions, the length and the width. Examples of 2D shapes in a flat geometry.

Formal geometry:

• There is a sub-field of geometry called formal geometry which is related to algebraic geometry and deals with topics such as formal schemes , topological rings , the comparison theorem in algebraic geometry , the Grothendieck existence theorem. It is taught in secondary and senior secondary classes because it requires logical and abstract thinking.

Informal geometry:

• Informal geometry has the topics of definitions, measurements, and constructions of geometric shapes and figures. No attention to formal proof is given. Subtopics include points, lines, angles, triangles, quadrilaterals, circles, area, and perimeter. Therefore, it is taught in primary classes.

Proportional Reasoning: It involves understanding the multiplicative relationships between rational quantities (a/b = c/d), and is a form of reasoning that characterizes important structural relationships in mathematics and science.

• Proportional reasoning is the ability to compare ratios or the ability to make statements of equality between ratios.

• Proportional reasoning is foundational to understanding fractions.

• Proportional reasoning involves, detecting, expressing, analyzing, explaining, and providing evidence in support of assertions about, proportional relationships.
• It involves thinking about the relations among relations.

Jean Piaget's Views:

• Proportional reasoning represents a cornerstone in the development of children’s mathematical thinking.

• Piaget considers the ability to reason proportionally to be a primary indicator of formal operational thought, and this stage is viewed as the highest level of cognitive development.

• Proportional reasoning helps in understanding the concept related to ratio and proportion.

• Ratio and proportion are critical ideas for students to understand.

Piaget’s Concept of Formal Operational Thought:

• It is associated with one’s ability to reason proportionally. 
• The attainment of proportional reasoning is considered a milestone in students’ cognitive development.
• Piaget described the development of proportional reasoning in three stages:-

1. Students are not aware of ratio dependence and seek solutions by guessing. 
2. Students are aware of objective dependence.
3. Proportionality is discovered and applied to obtain correct solutions.

NOTE:

• Van Hiele describes how people learn geometry. According to his theory, there are five levels of thinking in geometry.
• Zoltan Dienes stands with those of Jean Piaget and Jerome Bruner as a legendary figure whose theories of learning have left a lasting impression on the field of mathematics education.
• Lev Vygotsky propounded the 'Socio-Cultural Theory'.

Hence, it becomes clear that the role of proportional reasoning in understanding the concept related to ratio and proportion was highlighted by Jean Piaget.

Learning Mathematics is concerned with both comprehending the facts, theories, rules, and laws, and with the aim of learning mathematics which is much broader. As a teacher, one should make his/her students understand that mathematics has various applications in daily life. Similarly, it is the duty of the teacher to convince students that mathematics is not a subject to be learned by rote learning. Children do come across situations to solve problems, and for the same, mathematical reasoning is used.

• Mathematical reasoning enables children to arrive at solutions/judgments/conclusions after manipulating the facts involved in the problems. To solve problems, children evaluate situations, select problem-solving strategies, draw logical conclusions, develop and describe solutions, and recognize how these solutions can be applied. 
• Spatial reasoning involves composing and decomposing shapes and figures, visualization, or the ability to mentally manipulate, rotate, twist, or invert pictures or objects, spatial orientation, or the ability to recognize an object even when the object’s orientation changes.

Important Points

Activities to develop spatial reasoning among students:

• Navigation to find a way.
• Parking the car in a parking lot.
• Tessellating the plane with the motif to get a tessellation of a horse and rider.
• See a variety of tilings -on floors, on walls, decoration pieces, etc.
• Judge where the ball will land when playing ball games, such as tennis, basketball, or soccer.
• Figuring out how many items are able to fit into a box of a certain size.

Key Points

A tessellation is another name for tiling, which is used by artists more than mathematicians. Tessellations use either a single shape which may or may not be regular or at most a few shapes, to cover the plane. The emphasis is on using shapes that look natural like birds, fish, horses, people, etc., rather than pure geometric forms. Through the following activity, you can pick up some basic principles involved in creating tessellations and make some of your own tilings.  

Look at the picture:

NOTE: 

• Solving Sudoku puzzles develop problem-solving ability.
• Drawing bar graphs to represent data develop creativity skills
• Identifying patterns in a number chart develop the skills of tracing pattern.

Hence, we can conclude that Identifying tessellating figures is most likely to develop spatial reasoning among students.

Children should be exposed to verbal problems at an early stage, not after they have 'learned their facts. While you are interacting with a child, look for natural opportunities to ask the child a verbal problem about the concept you are helping her learn.

Key Points

Broadly, there are two models of word problems involving addition, that children are exposed to, namely: 

• Augmentation -.where a quantity is to be increased (or augmented) by some amount, and the increased value has to be obtained. (e.g., to a crate containing 5 bottles, 4 more are added. How many bottles in the crate now have?) 
• Aggregation - when they need to combine two or more quantities (like sets of objects, money, distance, volume, etc.) to obtain a single quantity. (e.g., if Munni has 3 pencils and Munna has 2, how many pencils are there altogether?). 
• “A basket contains 5 apples and 7 more apples are added to it. How many apples are now there in the basket?” It is an aggregation structure since two quantities combine.

Hence, we can conclude that the above word problem is related to aggregation.

Mathematical proficiency is the ability to understand concepts and competently apply five interdependent strands of mathematical proficiency.

These five interdependent strands are as follows:-

1. Conceptual understanding
2. Procedural fluency
3. Strategic competence
4. Adaptive reasoning
5. Productive disposition

 Important Points

The following should be the sequence of developing proficiency in mathematics language-

1. Everyday language- everyday language is used so that students can understand the problem easily,
2. Mathematized situation language- then mathematized situation language is used so that child can correlate with the given problem.
3. Language of mathematical problem solving- a child can understand language without even considering the situation.
4. Symbolic language- children require an upper level of visualization to solve the problem. it uses characters or symbols to represent concepts.

Hence, Everyday language → Mathematized situation language → Language of Mathematical problem solving → Symbolic language is the correct sequence of mathematical proficiency.

Mathematics is not just the study of numbers and statistical data but also studies the different types of shapes, figures, and patterns.

• In early schooling, the learners began to learn about shapes and try to differentiate various shapes from each other.
• The students learn according to their level of experience and their individual differences, the age can be different in each stage as they learn at their own pace. 
• Van Heile's theory provides insight to the teacher about how students learn geometry at different levels. It originated in 1957 given by Pierre Van Hiele and his wife from Utrecht University in the Netherlands.
• It helps in describing how the students learn at each level and pass to another level and shapes their learning of geometry at each level of learning.

Key Points

Van Hiele levels: The Van Hiele levels are described below:

Hence, it is concluded that at the visualization level of Van Heile's theory children can recognize geometric figures by their shape as “a whole” and compare the figures with their prototypes or everyday things but can not identify the properties of geometric figures.
