To help Melvin construct a line segment bisector using the paper folding method, the steps should be ordered as follows:
The first step is Option #2: Fold one endpoint of the line segment onto the other.
The second step is Option #3: Unfold the paper and label the intersection of the fold and the line segment with a point.
The third step is Option #1: Use a straight edge to draw a line through the point you have created.
