Which of the following teaching-learning resources would be the most appropriate to teach the concept of addition of two decimal numbers?

Options

A. Geoboard
B. Beads and string
C. Graph paper
D. Abacus

Answer

To solve the question of which teaching-learning resource is the most appropriate for teaching the addition of two decimal numbers, we can follow these steps:

### Step 1: Identify the Options
We need to consider the given options for teaching resources. The options might include:
1. Graph paper
2. Abacus
3. Geoboard
4. Number line

### Step 2: Analyze Each Option
- **Graph Paper**: Graph paper consists of a grid of squares, which can help visualize decimal numbers. Each small square can represent a decimal value (e.g., 0.01).

- **Abacus**: An abacus is useful for teaching addition and subtraction of whole numbers, but it can be less effective for decimal numbers.

- **Geoboard**: A geoboard is typically used for geometric concepts and may not be the best for teaching decimal addition.

- **Number Line**: A number line can also be used to visualize addition, but it may not provide the same level of precision as graph paper for decimal values.

### Step 3: Determine the Most Appropriate Resource
After analyzing each option, we find that:
- **Graph Paper** is the most suitable resource for teaching the addition of decimal numbers because it allows students to visualize and accurately represent decimal values. Each box can represent a specific decimal value, making it easier to perform addition.

### Step 4: Conclusion
Thus, the most appropriate teaching-learning resource to teach the concept of addition of two decimal numbers is **Graph Paper**.
