Understanding Place Value Up to 1 Million
What is Place Value?
- Place value refers to the value a digit holds based on its position in a number.
- Each position represents a power of 10.
- In our number system, each place value moves to the left (increases by a power of 10) or to the right (decreases by a power of 10).
Place Value Chart
- Place values are organised in a chart that helps visualize the number structure.
- The chart includes:
- Units (1)
- Tens (10)
- Hundreds (100)
- Thousands (1,000)
- Ten Thousands (10,000)
- Hundred Thousands (100,000)
- Millions (1,000,000)

Breaking Down Numbers
- Learn how to break down large numbers into their place values.
- For example, in the number 4,582, it can be broken down as:
- 4 thousands (4,000)
- 5 hundreds (500)
- 8 tens (80)
- 2 units (2)
- To read it, say: "Four thousand, five hundred eighty-two."

Writing Numbers in Words
- Practice converting numbers into words.
- Examples:
- 356,489: "Three hundred fifty-six thousand, four hundred eighty-nine."
- 1,020,405: "One million twenty thousand, four hundred five."
- This skill helps in understanding the numeric representations better.
Comparing and Ordering Large Numbers
- Learn to compare and order large numbers using place values.
- Steps:
- Compare the leftmost digits.
- If they are the same, move to the next digit.
- Use symbols: > (greater than), < (less than), = (equal to).
- Example: 452,300 < 953,100

Rounding Large Numbers
- Rounding helps simplify numbers while keeping an approximate value.
- Rules:
- Look at the digit to the right of the place you're rounding to:
- If it's 5 or more, round up.
- If it's less than 5, keep it the same.
- Example: Round 67,849 to the nearest thousand: it becomes 68,000.
