Abstract: There are several known exact results on the crossing numbers for join products for small graphs of order at
 most five.This paper further studies the join of graphs,and give the exact values of crossing numbers for join products S5∨Pn and G∨Pn for other five graphs G of order six.

Key words: graph, crossing number, join, drawing, path
