How do you ungroup a 3 digit number? My nephew is working on his homework and I have no clue how to help him.
Talja [164]

In monetary terms, you're making change. If you need more ones, you trade one 10 for 10 ones.

When I was in school, many years ago, we used small superscript-type numbers to show this:

  7 3 0 ⇒ 7 2 ¹0 . . . . regrouping to gain 10 ones

  7 2 ¹0 ⇒ 6 ¹2 ¹0 . . .regrouping again to gain 10 more tens

You'd have to look at the example problems that precede this page in order to see what the meaning of "magnifying glass" is.
