Comparing and ordering numbers up to ten thousands
Comparing and ordering numbers can be further extended to ten thousands for 3rd grade kids. As explained in ICS-Grade3math under Standard 1: Number and Operations, under Objective 1, "When comparing numbers between 1,000 and 9,999, numbers will differ in only hundreds and thousands places. When comparing, the symbols for greater than and less than will not be used. When ordering, no more than four values are used. Numbers may be ordered least to greatest or greatest to least."
Place value skills can assist the kids to compare and order numbers. When we compare two numbers, we compare their digits from left to right. The rule of thumb to compare numbers is that 4 digit number is greater than a 3 digit number and a 3 digit number is greater than a 2 digit number.
If two numbers have the same number of digits then we need to compare each and every digit stating from left to right side of the number.
