I made this Power Point for Unit 8 of my high school student's textbook "High School English I" by Anna Dahland Kim (with the orange cover). This is a unit based on the 1960's in the USA. I showed them slides about the fashion, music, politics and cultural changes of this time, trying to describe how exciting it was to be a teenager during that decade. The students stayed pretty interested, mostly because they knew who some of the people were and they called Bob Marley's dreadlocks "Reggae hair".
To follow up the power point, I printed out a list of key words, names of people from the slideshow and "things" like the Vietnam War and hippies and put them in a box. I would print the same words 2-3 times, and highlight them with a different color. I used these for a "review" game in the following week's class. I split the class down the middle to make 2 teams. Each student had to come up, draw a piece of paper, and act or draw until their team guessed the word for the point.
Here's how I did it:
One color meant that the student had to silently act out the person or thing without using any sounds.
Another color meant the student had to draw on the whiteboard/chalkboard the person or thing without using any words or symbols.
The third color meant the student could TALK like the person (i.e. JFK) saying something like, "I was a president but I was shot" so the students have a better hint.
The PPT with the YouTube video clips lasted almost the entire 50 minutes with discussion and explanation of some of the new words like "assassination". The following week, I did a quick review of the PPT and then we played the Pictionary/Charades game for the rest of the class, and it lasted the full 50 minutes.
