Which one of the following Teaching Learning Materials (TLM) is best suited to explain `1/10` is greater than `1/100` to Class IV students?

Options

A. Dienes block
B. Number chart
C. Abacus
D. 10 x10 square grid

Answer

To determine which Teaching Learning Material (TLM) is best suited to explain that \( \frac{1}{10} \) is greater than \( \frac{1}{100} \) to Class IV students, we can follow these steps:

### Step 1: Understand the Fractions
First, we need to understand what \( \frac{1}{10} \) and \( \frac{1}{100} \) represent.
- \( \frac{1}{10} \) means one part out of ten equal parts.
- \( \frac{1}{100} \) means one part out of one hundred equal parts.

### Step 2: Visual Representation
To illustrate this concept visually, we can use a grid. A 10x10 square grid is particularly useful because it can show both fractions clearly.
- A 10x10 grid has 100 small squares in total.

### Step 3: Filling the Grid
- If we shade one row of the 10x10 grid (which consists of 10 squares), it represents \( \frac{1}{10} \).
- If we shade one square out of the 100 squares in the entire grid, it represents \( \frac{1}{100} \).

### Step 4: Compare the Shaded Areas
Now, we can compare the shaded areas:
- The shaded area for \( \frac{1}{10} \) (10 squares) is much larger than the shaded area for \( \frac{1}{100} \) (1 square).

### Step 5: Conclusion
From this visual representation, it becomes clear that \( \frac{1}{10} \) is indeed greater than \( \frac{1}{100} \). Therefore, the best TLM to explain this concept to Class IV students is a 10x10 square grid.

### Final Answer
The answer is a **10 into 10 square grid**.
