A teacher introduced multiplication in her class as repeated addition and then by grouping of same number of objects taken multiple times she introduced the `'xx'` symbol and further conducted a small activity of finding product using criss-cross lines or matchsticks. Here, the teacher is

Options

A. providing remedial strategies for low achievers in Mathematics
B. using multiple representations to make the class interesting
C. developing a lesson and taking students 'from concrete to abstract concept'
D. catering to learners with different learning styles

Answer

To solve the question regarding the teacher's approach to introducing multiplication, we can break down the information provided and analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding the Teacher's Method**: The teacher introduced multiplication as repeated addition. This means she is trying to help students understand multiplication by relating it to something they already know—adding the same number multiple times.

**Hint**: Think about how multiplication can be visualized as adding the same number repeatedly.

2. **Grouping of Objects**: The teacher further explained multiplication by grouping the same number of objects taken multiple times. This visual representation helps students grasp the concept of multiplication as a way to combine groups of objects.

**Hint**: Consider how grouping can simplify understanding of larger numbers and multiplication.

3. **Introduction of the 'xx' Symbol**: By introducing the multiplication symbol ('xx'), the teacher is transitioning from a concrete understanding (using objects) to an abstract representation (using symbols).

**Hint**: Reflect on how symbols in mathematics represent operations and concepts.

4. **Activity with Criss-Cross Lines or Matchsticks**: The teacher conducted an activity to find products using criss-cross lines or matchsticks. This hands-on activity further reinforces the concept of multiplication in a tangible way.

**Hint**: Think about how hands-on activities can enhance learning and understanding of mathematical concepts.

5. **Analyzing the Options**:
- **Option A**: Providing remedial strategies for low achievers in mathematics. This does not fully capture the teacher's approach.
- **Option B**: Using multiple representations to make the class interesting. This option aligns with the teacher's use of various methods to explain multiplication.
- **Option C**: Developing a lesson and taking students from concrete to abstract concepts. This is also a strong contender as the teacher is indeed moving from concrete (objects) to abstract (symbols).
- **Option D**: Catering to learners with different learning styles. While this may be true, it is not the primary focus of the described method.

6. **Choosing the Best Option**: The best option that encapsulates the teacher's approach is **Option C**: developing a lesson and taking students from concrete to abstract concepts. This option highlights the progression in understanding multiplication through various methods.

**Hint**: Consider which option best describes the overall teaching strategy employed by the teacher.

### Final Answer:
The correct option is **Option C**: developing a lesson and taking students from concrete to abstract concepts.
