Understand why the standard algorithm for subtraction is based on place-value.
2:
Understand that when subtracting a multi-digit number, each place-value is being subtracted individually to create the new number (ones are subtracted from ones, tens are subtracted from tens, etc.)
3:
Understand how to regroup based on place-value understandings (i.e., ten ones can be composed into one ten – ten tens can be composed into one hundred).
4:
Understand that subtraction equations can be written both vertically and horizontally.
