The Iron Giant" to my junior high students. The film is 90 minutes or so and fits comfortably in a 2 lesson block. That left me with what to do with my elementary kids. I thought I could show them the same film but their lessons are 45 minutes and with greetings, roll call and so on that gives us about 35-40 minutes of useful time to watch something.
So I scoured the web and found a good youtube video of the series from ALF. If you are unfamiliar, ALF is a 1980s sitcom about an alien life form ALF that crashes on the roof of a garage of a family. The family then take the ALF in and he becomes part of their home. I got very lucky and was able to find the pilot episode and some English subtitles to match. I looked everywhere for Japanese subtitles but couldn't find anything. It would help kids to understand the plot better.
youtube video in Japanese to watch at home. After the film I asked many questions and kids that answered first and correctly got a sticker. It was a great break from the humdrum of studying and I think kids genuinely liked ALF. I'm glad I got to share a part of my childhood with them.
