This ppt is so great I used it for middle school too (took out the colouring). I also showed some pics from my summer vaca back home. Then, I made a speaking comparison game. You will need dice (they're only 300 won at Art Box

or some other point-awarding tool.
Pre-game: Have the students fill out the worksheet (I did one example together with the class, and let them work in small groups to finish). They don't have to finish, but this worksheet will help them play the game.
How to play: If you can, put students into groups of two. First player chooses a grey category card, and then must give one example. If they say a correct sentence from within that category, they can roll the dice and receive those points. Then, they can choose a white card. The white cards are pretty self-explanatory, but if your students are shy or don't like being silly you might want to change a couple of them.
The "BATTLE" white card is fun, and you'll be surprised what your students come up with! It REALLY gets them talking. To battle, player 1 and player 2 take turns making comparisons between Canada and Korea for that category. They continue until one player cannot make a sentence. That player must surrender half of their points to the battle winner. (If they don't have points to surrender, the winner receives 10 pts).
To simplify:
1. Grey card
2. Make sentence
3. Roll dice
4. White card
Player 2's turn. Repeat.
This worked MUCH better than I expected it to, so I hope it works well for you too ^^
