One of the customs of the Sioux was for a woman who was interested in a man to stand outside her teepee at night. She would wrap herself in a blanket and wait for the man to arrive. Another custom was for women of the tribe to dance on the morning of a wedding.
They spoke different languages
The mandan tribe did use the buffalo
They got there food by hunting buffalo and growing crops.
Buffalo and the three sisters corn,beans,squash
to hunt buffalo

The buffalo dance is where the young men are chosen to do it. It was a great honour to do it and the people that did it they would be remembered as the buffalo dancers.
the buffalo dance waas done because they celbrated themselves killing a buffalo dressed as wolves and dancing around the bufaalo singing and dancing
"Mandan Plains" makes no sense - the Mandan tribe were not a Plains group but lived in semi-permanent villages along the upper Missouri river. They are classed as "marginally Plains" because they were not primarily nomadic buffalo hunters.The Mandan women grew the usual crops of maize (Indian corn), beans and squash, along with sunflowers for their nutritious seeds. Men would hunt deer and buffalo occasionally out on the Plains, or visited other tribes to exchange their own produce for hides and meat.
women grew crops such as corn beans squash and sunflowers and the men hunted deer and other small game, but seasonally the mandan would hunt buffalo which became a very reliable food source
the sun dance was danced because they thought it healed the injured. so if someone was ill they danced it believing the ill person would get better. the buffalo dance was a dance that the Plains Indians did when they had ran out of buffalo. They would do this to ask their god for more buffalo.
