This is the story of the great Gaelic hero Fionn MacCool and why he sucks his thumb. The tale introduces children to Gaelic storytelling and oral tradition and is perfect for reading aloud in a classroom or group. In the introduction, actions or gestures are given that match with nine keywords in the story. Children can perform the matching action whenever they hear each keyword as the story is read aloud.
The book contains two versions of the action story, the first in English, and the second in English with nine Scottish Gaelic words instead of the English action words. After children become familiar with the all-English version, the second version with Gaelic action words can be introduced. The actions are the same in both versions, and act as a bridge to introduce the Gaelic words and build awareness of the language.
