first make a table with the tens on the left side, the stem, and the unit on the right, the leaf.Then list the tens smallest to largest e.g 42 would be 4as the ten and 2 as the unit __4_|___2__ __6_|___7__ carry this on until all the numbers are listed, but if there is more than one number with the same ten it will be listed like this: __7|__3__8 I hope this helps
