regroup

2 tens, 2 ones; 1 ten, 12 ones
Name the word that describes what was done to show the number in different ways.

The word that describes what was done to show the number in different ways is "regroup".

To understand how regrouping works, let's break down the numbers given in the question:

First, we have "2 tens, 2 ones." This means we have 20 (2 tens) + 2 (2 ones) = 22.

Then, we have "1 ten, 12 ones." This means we have 10 (1 ten) + 12 (12 ones) = 22.

By regrouping, we are rearranging the digits to show the same value in a different way. In this case, both representations result in the number 22.

Regrouping is a strategy used in place value where we rearrange the digits according to their place value positions (such as tens and ones) to make it easier to perform calculations or represent numbers in different forms.
