Final answer:
Shawnee extended families spent winters in dome-shaped tentlike structures called wigwams or lodges, which were built from wooden poles and covered with bark or woven mats.
Step-by-step explanation:
The Shawnee extended families typically spent winters in tentlike structures known as wigwams or lodges. These structures were commonly used by various Native American tribes, including the Shawnee, during the winter months. Wigwams were dome-shaped and built using a frame of wooden poles covered with sheets of bark or woven mats. They were semi-permanent, providing shelter from the cold while being relatively easy to construct and dismantle as needed. This type of housing allowed the Shawnee to maintain their mobility while still having a sturdy shelter to protect them from the harsh winter conditions.
