It has come to my attention that the tribe of Benjamin was considered one of the northern tribes during David's kingdom. After the split the southern kingdom was named Judah, and the northern kingdom named Israel. Benjamin became part of Judah. What are the particulars of that being so?

In addition, Simeon was part of Judah during David's kingdom. Again, after the split who did they numbered as the ten tribes of the northern kingdom? Seems as if Judah, Simeon, and Benjamin were out of the mix, then how did they get to the 10 tribes in the northern kingdom? Must must have counted the two half-tribes as two.
