This collection of lesson plans explores winter counts which are pictographic records of historical/memorable events for a tiospaye (community). The pictures, which were used as mnemonic devices, are arranged in chronological order. Originally, the memorable events were recorded on rock, buffalo hide, deer hide, cow hide, and then ledger paper and muslin (cotton fabric). Each tiospaye designated a winter count keeper. The keeper (traditionally a man) of the winter count was the historian for the community. The images on the winter count were used as a reminder/aid to help the keeper (oral historian) remember the events.
