### Grade 1 - Mathematics2.7 Tens and Ones

Explanation:

Can you count the number of stars shown below?

## * * * * * * * * * * * * *

There are thirteen stars above. You can group them as below:

## * * * * * * * * * * * + * * * = 10 stars + 3 stars

In other words, we can write
13 = 10 + 3 = 1 ten + 3 ones

Therefore, in 13, the digit '1' is in tens place and the digit '3' is in ones place.

Example:
In 27, which digit is in the tens place?
