    LOVE these. I give the following story problems, based on what my Gram would have called the real, true Irish myth. Tomie dePaola has a book about it, but his gram got the names all wrong.

    Big Trouble.
    Finn Mac Cumhail, (pronounced McCool) leader of the ancient Fianna warriors, and gifted with “magic, insight and the power of words” when he was the first to eat of the Salmon of Knowledge, and ended up a giant. One of his rival giants, Benandonner, lived across the sea in Scotland. Benandonner wasn’t able to swim across the sea to Ireland for a proper gigantic challenge so Finn tore pieces of volcanic rock into columns to make the causeway to Scotland.

    Benandonner came across to Ireland and Finn’s house, where Finn was dressed up as a baby. Yes, a baby over 15 feet long! The “baby” bit the Scottish giant’s hand off and the Scot took off for Scotland, terrified at how big Finn himself must be if his baby was so big.

    1) If Finn was really a 15 foot long baby, how tall would the father be? (State any assumptions clearly.)
    2) Say a typical 6-foot tall Celtic Warrior weighs 9 stone. (Ancient weight measure.) How much might the 15 foot tall Finn weigh? (Weight, density being equal, corresponds roughly with volume.)
    3) If it takes three square yards of wolf pelt to make a fierce looking warrior garb for your typical 6 foot warrior, how many much material would Finn need to make a costume? If that takes two wolves for 3 square yards, how many wolves for Finn?
    4) Give the measurements (dimensions, area, volume, weight, etc.) of a giant sized something you might find in Finn’s house. (Iron cooking skillets feature heavily in the Benandonner story, but don’t feel limited by that.)
