To introduce subtraction of two digits numbers in class 3, a teacher proceeded in the following steps
Step 1: Revision of two digit numbers with an understanding of the place-value system
Step 2: Use tally marks to show that a smaller number can be subtracted on numbers under each column of place value. In this case, the teacher is developing the lesson.
  • a)
    From system concept/ algorithm/operations
  • b)
    From system concept/ operations/algorithm
  • c)
    From operations/ system concept/ algorithm
  • d)
    From algorithm/ system concept/ operations
Correct answer is option 'A'. Can you explain this answer?

Firstly, the teacher wants the students to learn the place-value system. So the teacher starts from the system concept. Then the teacher taught the rules of subtraction and the set of rules to be followed in calculations or problem-solving operations. So by explaining this, the teacher uses the algorithm, and then the teacher taught the application of subtraction on a number that is an operation of subtraction. So, the sequence of the lesson is: 
From system concept→algorithm→operations

Understanding the Correct Answer:

Explanation:
The correct answer is option 'A' because the most effective way to introduce subtraction of two-digit numbers in class 3 is by starting with the system concept or understanding of operations before diving into the algorithm.

From System Concept:
- By revising two-digit numbers and reinforcing the place-value system, students will have a solid foundation to understand subtraction.
- Understanding the value of each digit in a number helps in grasping the concept of subtraction better.

From Algorithm:
- Once students have a good grasp of the system concept, they can then move on to learning the subtraction algorithm.
- Introducing the algorithm too early without a strong foundation may lead to confusion among students.

From Operations:
- Teaching subtraction as an operation helps students understand the concept of taking away or finding the difference between two numbers.
- By using tally marks to show subtraction visually, students can better comprehend the process.

Therefore, by following the sequence of starting with the system concept, moving on to operations, and then introducing the algorithm, students can build a solid understanding of subtraction of two-digit numbers in class 3.
