There is still archaeological evidence of the Picts in Scotland, but no written records. The Picts were mainly farmers and lived on one side of the Grampian mountains. The Scotti were also farmers, but lived on the opposide side of the mountains. They also spoke a completely different language.
Students could draw a map showing Ireland, Dalriada, Pictland and the Grampian Mountains. Students could list the reasons why some historians believe the Scotti came from Ireland and why some think they always lived in Dalriada. Students could give their opinions on the origins of the Scotti, citing evidence to support their thinking.
