Understanding Place Value in Multi-Digit Numbers

In this presentation, we will explore the concept of place value, specifically focusing on how a digit in one place represents ten times what it represents in the place to its right. This presentation will help you understand how to read and write multi-digit numbers!

What is Place Value?

• Definition: Place value is the value of a digit depending on its position in a number.
• Multi-Digit Numbers: These are numbers that have more than one digit (e.g., 10, 345, 6789).
• Importance: Understanding place value helps us do math, read numbers, and write numbers accurately.

---

Digits and Their Values

• Digits: We use ten digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9).
• Value of Digits: The value of a digit depending on its place:
  • For example, in the number 345, the digit "5" is in the ones place, so its value is 5.
  • The digit "4" is in the tens place, so its value is 40 (4 x 10).

Place Value Chart

• Place Value Chart: A table to help visualize the value of each digit in a number.
• Visual Representation:
  • Ones, Tens, Hundreds, Thousands, etc.

Understanding the Concept of Tens

• Tens Place:
  • A digit in the tens place is ten times the value of the same digit in the ones place.
  • For example, the digit "3":
    • In 3 (ones place) = 3
    • In 30 (tens place) = 30 (3 x 10)

---

Practice with Place Value

• Example Numbers:

  • What is the value of the digit "7" in 7,845?
  • Answer: 7,000 (7 x 1,000)

• Try This: Find the value of "2" in 2,456.

---

Breaking Down a Multi-Digit Number

• Example: Take the number 1,234.

  • The digit 1 = 1,000
  • The digit 2 = 200
  • The digit 3 = 30
  • The digit 4 = 4

• Rewrite in Expanded Form: 1,234 = 1,000 + 200 + 30 + 4

---

Using Place Value to Compare Numbers

• Comparing Numbers:
  • Use place value to determine which number is larger.
  • For example, compare 753 and 735:
    • In 753, the "7" is in the hundreds place, whereas in 735, the "7" is also in the hundreds.
    • Compare next digits: "5" vs "3".

---

Real-Life Applications of Place Value

• Money: Understanding how to count money (e.g., $10, $20, etc.).

  • Knowing that a $10 bill is ten times greater than a $1 bill.

• Distance: Learning about miles or kilometers.

  • E.g., a distance of 50 miles is ten times greater than a distance of 5 miles.

---

Summary of Place Value Concepts

• Key Takeaways:
  • Each digit's value is determined by its position.
  • The place to the left represents ten times the value of the place to the right.
  • Understanding place value helps in reading, writing, and doing calculations with numbers.
