Regrouping of Numbers From Ones to Tens and Tens to Ones

Regrouping of Numbers from Ones to Tens:

Writing a number in various methods is called regrouping.

Let us think about the number 18. We can think about it in these 2 methods:

18 ones can be regrouped as 1 10 8 ones.

Now, think about the number 24.

Again, 2 10s 15 ones is the exact same as 3 10s 5 ones.

More Examples:

18 ones = 1 10 + 8 ones

14 ones = 1 10 + 4 ones

3 10s + 12 ones = 4 10s + 2 ones

5 10s + 19 ones = 6 10s + 9 ones

1 10 +18 ones = 2 10s + 8 ones

Regrouping of Numbers from Tens to Ones:

Let us think about the number 16. We can think about it in 2 methods.

1 10 6 ones can be regrouped as 16 ones.

Now, think about the number 23.

2 10s 3 ones can be regrouped as 1 10 13 ones.

Again, 3 10s 2 ones is the exact same as 2 10s 12 ones
