Numerical order for whole numbers from 0 through 20 establishes that each number has a fixed position in a sequence: numbers increase by one from left to right, with a successor and predecessor except at the endpoints. This understanding supports comparing quantities and numerals, arranging numbers in ascending or descending order, and interpreting their positions on a number line; ordering larger numbers or using more general place-value rules is beyond this scope.
To put numbers in numerical order, arrange them from smallest to largest. On a number line, numbers get larger as you move to the right.
Example: Put , , and in order from smallest to largest.
Find the smallest number.
comes before and , so it is the smallest.
Find the next number.
comes after but before .
Place the largest number last.
is the largest.
So, the numbers in order are:
Remember: Count forward to find which number comes next. The number farther to the right on a number line is greater.
