Regrouping of Numbers
Regrouping of Numbers from Ones to Tens:
Writing a number in different ways is called regrouping.
Let us consider the number 18. We can think of it in these two ways:
18 ones can be regrouped as 1 ten 8 ones.
Now, consider the number 24.
Again, 2 tens 15 ones is the same as 3 tens 5 ones.
More Examples:
18 ones = 1 ten + 8 ones
14 ones = 1 ten + 4 ones
3 tens + 12 ones = 4 tens + 2 ones
5 tens + 19 ones = 6 tens + 9 ones
1 ten +18 ones = 2 tens + 8 ones
Regrouping of Numbers from Tens to Ones:
Let us consider the number 16. We can think of it in two ways.
1 ten 6 ones can be regrouped as 16 ones.
Now, consider the number 23.
2 tens 3 ones can be regrouped as 1 ten 13 ones.
Again, 3 tens 2 ones is the same as 2 tens 12 ones
