Detailed Solution for MPTET Varg 2 Math Mock Test - 4 - Question 22

Mathematics is the study of numbers, shape, quantity, and patterns. The nature of mathematics is logical and it relies on logic and connects learning with learners' day-to-day life.

  • Teaching methods of mathematics include problem-solving, lecture, inductive, deductive, analytic, synthetic, heuristic and discovery method. Teacher adopts any method according to the needs and interests of students.

Key Points

Anisha is using deductive logic.

Deductive Method: The deductive method is based on deduction. At first, the rules are given and then students are asked to apply these rules to solve more problems.

  • It begins with general premises and through logical argument, comes to a specific conclusion.
  • For example, while teaching mathematics, the teacher introduces a theory and explains the rules of the theory and the formula, and the students are asked to solve problems using the given formula.
  • Deductive approach proceeds from-

    • General to specific
    • Unknown to know
    • Complex to simple
    • Formula to example

In the above example Anisha proves it by taking the case n i.e, she uses the method from unknown to known.

MPTET Varg 2 Math Mock Test - 4 - Question 23
Which of the following is the best teaching method to teach about shapes at primary level?
Detailed Solution for MPTET Varg 2 Math Mock Test - 4 - Question 23

Mathematics is the study of patterns, numbers, geometrical objects, data, and information. It deals with data analysis, integration of various fields of knowledge, involves proofs, deductive and inductive reasoning, and generalizations.

  • The teaching of mathematics should be done in the way, in which a student learns the best i.e., following the child-centered approaches by engaging students actively in the learning process.
  • The teacher should focus more on providing practical exercises and abstract knowledge to students to foster their individualized discovery-oriented learning.

Key Points

  • The primary class students need a solid foundation in geometry in order to be successful later in middle school and high school geometry.
  • The geometry content appropriate to the primary classroom is informal in the organization and should be presented in a way that allows students to construct meaning.
  • Classroom activities should encourage students to observe, compare observations, make hypotheses, and then prove or disprove their hypotheses.
  • The geometry presented in elementary classrooms focuses mainly on the identification and concrete observation of basic shapes.
  • At the primary level, the teacher mainly expects their students to observe and identify the different shapes such as square, rectangle, triangle, pentagon, hexagon, etc.
  • For example, the students should be asked to observe the shapes of their bottle, lunch box, pencil box, table, desk, and all other objects that are present in their surroundings.
  • When students are able to observe and identify the geometrical shapes only then they will be able to define and draw them.

Hint

  • Showing charts with different shapes, drawing several shapes on the blackboard, and giving oral knowledge about shapes will not help that much in teaching shapes as the students will not get concrete experience.

Hence, it is concluded that using concrete materials is the best teaching method to teach about shapes at the primary level.

In fact, this organized and safe discussion forum encourages students to share and challenge ideas.
  • Importantly, students are reassured that their voices, ideas, and experiences are valued and contribute directly to the whole class's learning.
  • During Gallery Walk, Math Congress, and Bansho, it becomes evident to the students and teacher that mathematical communication is not about “answering the question using words, numbers, pictures, and symbols.” Instead, they realize that these forms of communication are selected and applied in order to create a precise mathematical argument, where labeled diagrams and/or numeric expressions and equations are viewed as being more precise, concise, and persuasive forms than descriptive narratives.

Hence, remedial teaching is not one of the methods of coordinating student discussion and analyzing their solutions in Mathematics.

HintRemedial teaching refers to teaching which is intended to improve the ability of slow learners to learn something. It is an integral part of the teaching-learning program, also known as compensatory or corrective teaching.

Additional Information

  • Gallery Walk is an interactive discussion technique that gets students out of their chairs and into a mode of focused and active engagement with other students’ mathematical ideas.
  • Math Congress is a mathematics instructional strategy developed by Fosnot and Dolk. The purpose of the congress is to support the development of mathematicians in the classroom learning community, rather than fixing mistakes in the children’s work or getting agreement on answers.
  • Bansho, in Japanese, literally means board writing. The purpose of Bansho is to organize and record mathematical thinking derived from and collectively produced by students on a large-size chalkboard or dry-erase board.
