Ā Ā Ā Ā Ā All numbers are made up of digits.
We can write any number using just ten digits:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Tip: These are the only 10 digits in all math.
How can we make numbers larger than 9? š¤
We put two or more digits together.
For example, 5 has one digit:
38 has two digits:
To count up to 9, we only need one digit.
What happens after 9? š¤Ā
We start using two digits:
Tip: after 9 comes 10, not 01.
We say the number 10 is made up of 1 Tens, and 0 Ones.
Tens and Ones are called place values.Ā
Each digit in a number has a place value.
Ā Ā Ā Ā Ā Place values tell us how much each digit in a number is worth.
Ā Ā Ā Ā Ā Digits on the left (š) have a bigger place value.
Digits at the Ones place count as 1 each. Digits at the Tens place count as 10 each.
For example, 24 has 2 Tens and 4 Ones.
To count up from 10, keep adding 1 to the Ones place until you get to 19.
What comes next?Ā
Yes! 13, 14, 15, 16, 17, 18, and 19.
After 19, you'll regroup another 10 Ones into a second Tens.
Ā Ā Ā Ā Ā There are only 10 different digits to make numbers with.
Digits: 0 through 9
We make big numbers using two or more digits next to each other.Ā
Ā Ā Ā Ā Ā We know how much each digit is worth, because of its place value.
Ā Ā Ā Ā Ā Digits on the left (š) are bigger than the digits to their right (š).
Great job learning about place values.Ā
Now, try practicing what you learned.
