Wither Battle Regrouping

CCSS.MATH.CONTENT.4.NBT.A.1 Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right.

Guiding Ideas

Start by investigating these questions with your students:

Why is Base 10 Called Base 10?

Is there such a number as “sixty twelve”? (the video in the Single Player World explains this).

What happens when any place value reaches 10?

How is this related to expanded form?
