Ask anyone if they know where the Olympics was this year (answer, Rio) Play the intro song.

Go through the ppt. Have kids read. At the end ask them what is the most interesting thing they know about the Olympics. They can talk about this in pairs.

Go through the next few slides. Between slides is a controlled practice with a lot of different years that kids can say. Call on individual students for this. (Years like 306 are "three oh six")

Go on to the mother slides. Have kids read the demo sentences and then make up on their own. Then get two kids to come to the front. One says a mother sentence and the other has to write what s/he hears.

Play "My mother did..." 2 students come up in front, the first says something cool (and made up) about mom - "My mother plays basketball", the next says something cooler about mom - "My mother played basketball in the Olympics" and so on. If a kid can't come up with anything, the other kid wins. Demo a few times in front of class, then the students can do it themselves in pairs. If there's time they can do fathers, grandparents, etc. If you want to incorporate the years you can make them start with "In [year], my mother..."

Play the "year 2525" song. Kids won't be able to follow all of the words but hopefully they'll enjoy the strange images.
