In the last lesson, you reviewed the place values up to hundred thousands.
In this lesson, let's learn even larger place values.
One thousand has 3 zeros. 1,000.
One million has 6 zeros. 1,000,000.
One million is one thousand times bigger than one thousand.
Commas go between every three places in a number.
Each place value is worth 10 times more than the one on its right.
We can use a place value table to keep track of the value of each digit in a number.
Pause, and study the names of each place above.
Tip: When writing a number in a place value table, always start with the digit on the farthest right. ➡️ This is the digit with the lowest place value.
Find the value of each digit in 3,456,728.
Let's start with the rightmost digit, 8.
It goes in the Ones place column.
It's worth 8 Ones.
Then, we fill in the rest of the digits.
Good job! 🎊
What's the value of the left-most digit in 23,716,984?
Let's put this number in a place value table.
We see that:
2 is in the Ten Millions place.
So the value of the left-most digit is:
2 x 10,000,000 = 20,000,000 or twenty million.
Great work.
What's the value of the left-most digit in 729,354,168?
Let's write the digits in a place value table:
The 7 is in the Hundred Millions column.
So its value is 7 x 100,000,000 = 700,000,000 or seven hundred million.
Fantastic job reviewing place values up to the Hundred Millions.🎉
Now, let's ace the practice.
