Compare and Order Numbers to 100,000 Higher

Children first compare pairs of numbers and then move on to ordering sets of
three or more numbers.
Ask,
" When comparing two numbers with the same number of
digits, if their first digits are equal in value, what do you
look at next?"
" What is the difference between ascending and
descending order?"
“What is different about comparing numbers with the same
number of digits and comparing numbers with different
numbers of digits?”
