Write the numbers in order from least to greatest. For example, 11, 12, 12, 15, 24, 27, 35, 52, 119
Draw a vertical line on a sheet of paper. The length of the line depends on the number of numbers that will be recorded and how size of your script.
Place the tens (or greater) digit on the left side of the line vertically in ascending order. These digits represent the "stems." For example:
1 I
2 I
3 I
5 I
11 I
Place the ones digit for each number on the right side of each line. These numbers represent the "leaves." For example:
1 I 1 2 2 5
2 I 4 7
3 I 5
5 I 2
11 I 9
Make a key to indicate the place values of the stems and leaves. For example, the following represents 119:
11 I 9
