  • Great and fun lesson. I included a game which was a list of 10 inventions ranging from the wheel to the internet- students in groups had to chronologically place the date of the invention.

  • I've used this a couple of times as a basic for a short project, and it works well. I usually set a context for their chindogu inventions, with a task of improving the school environment they're in. My guiding question is 'how can we design and promote a product that enhances the [summer school name] experience?', but with the caveat that it has to be a bit 'unuseless'. After planning and designing in pairs, I use Jamie Keddie's elevator pitch lesson ( as the basic for introducing the concept of a two-minute sales pitch. The students then write a sales pitch, peer correct it, and then have a sales fair competition in which they compete to attract investments from 'investors' (visiting students from other classes armed with a budget of fake money). The sales fair is an open 'free-for-all', so students also have to use language to attract/flatter visitors ('hey Sir, you're looking good today. Do you have a minute to spare? Have you ever had a problem with...?')

    There's so much you can do to extend this excellent lesson plan :)

  • Quite, Nick 2. The production phase is always create your own chundogu

  • This lesson is fantastic, thank you so much. I did it with a one-on-one student and we filled about 75 minutes, and I also did it with a class, and it raised much debate! It filled about 90mins. I also added a few more images that I found online, and some discussion questions.

    Thanks for uploading it, much appreciated.

  • I did this lesson yesterday with a group of teenagers and it lasted about an hour and twenty minutes. But that was with the extension activity - which I think is integral.
    I asked my class to brainstorm some inventions of their own then choose the best one and do a presentation pitching that invention to the class. They had to come up with a name, a slogan then draw it on the white board and explain the basic idea. I made the rest of the class rate each one of the inventions out of 5 in 4 different categories: "Is it unique? Is it convenient? Is it innovative? Is it creative?"
    I think this is a great lesson, my students found the inventions in the plan really funny and they were very enthused to make their own.

  • How could you stretch this lesson to 90min!?
    ..More like 25, if that.
