Lesson Point:
English-style Romaji

The Plan:
The object of this is to practice the English style of romaji.
The kids are generally taught the Kunrei-shiki or Nihon-shiki style of romaji at elementary school. Unfortunately, while useful to Japanese speakers, these stlyes are not very intuative to English speakers who have never learned Japanese. Thus, most words that have come into use in English use the Hepburn style of romanization. The kids have to learn to use this at the jr. high level.
There is a table of the different styles here on Wikipedia.
After explaining this to the kids and getting them to practice with their own names, this is a quick follow up. All of the words can be used in English, though some of them are not popular words depending on where you live. Feel free to adjust the words to your own region.
The explanation at the top of the page is about how there are some words that have their roots in other languages and then asks what the meaning of each of the English words below is.
After getting all the answers sorted out, it's a good idea to go over how the words are pronounced in English, and how the meaining is sometimes slightly different.
