Which one of the following statements is true?

Options

A. Zero should be introduced after number 9
B. Zero should be introduced at the time of teaching place value
C. Zero should be the first numeral to be taught
D. Zero should be introduced after children develop number sense

Answer

To determine which statement about the introduction of the number zero is true, let's analyze each option step by step.

### Step 1: Analyze the First Statement
**Statement 1:** "0 should be introduced after number 9."

- This statement suggests that zero should be taught only after students have learned about the number 9. However, this does not align with the understanding of numerical concepts, as zero is foundational to the number system.

**Hint:** Consider the role of zero in the number system and its importance in relation to other numbers.

### Step 2: Analyze the Second Statement
**Statement 2:** "0 should be introduced at the time of teaching place value."

- While place value is an important concept, introducing zero at this stage may confuse students who have not yet developed a solid understanding of numbers. Zero's role in place value is significant, but it may be premature to introduce it without prior number sense.

**Hint:** Reflect on how place value relates to the understanding of numbers and whether students need prior knowledge before learning about zero.

### Step 3: Analyze the Third Statement
**Statement 3:** "0 should be the first numerical to be taught."

- Teaching zero first can lead to confusion, as students may not yet grasp the concept of quantity or the role of zero in the number system. It is generally more effective to introduce numbers in a sequence that builds understanding.

**Hint:** Think about the natural progression of learning numbers and whether starting with zero makes sense.

### Step 4: Analyze the Fourth Statement
**Statement 4:** "0 should be introduced after children develop number sense."

- This statement emphasizes the importance of students having a foundational understanding of numbers before introducing zero. It acknowledges that students need to understand the concept of quantity and the role of zero in the number system.

**Hint:** Consider the importance of number sense and how it relates to the understanding of zero.

### Conclusion
After analyzing all four statements, the correct answer is:

**Option D:** "0 should be introduced after children develop number sense."

This statement is true because it ensures that students have a solid understanding of numbers before introducing the concept of zero, preventing confusion and enhancing their overall mathematical comprehension.
