I have an open class coming up with Grade 2 students. The lesson is based on topics found in Christian H. Kim's Middle School English 2 Chapter 11 but you don't need the textbook to be able to use this lesson. Would probably be OK for grade 1 and grade 3. This was taken from stuff that other people uploaded but edited and moved around a bit so credit goes to them (I can't remember their usernames).
 
I've uploaded a PPT and worksheets to use - There are 2 worksheets, one for Team 1 and one for Team 2 for the pair exercise. The back of both sheets are the same. Also included a relevant Blockbuster Game (which I've edited slightly but certainly didn't create) in case there's still time left at the end. Please give any feedback on how the lesson went and feel free to modify and reupload improved versions. Cheers

Part 1 - "Do you mind if...?" Battleships
(1) Go through the dialogue on slide 2, check SS understand meaning of "Do you mind if...?"  --> 5 mins
(2) Go through the next few slides explaining how to play the game.   --> 10 mins
(3) Students play the game in pairs (have them sit opposite each other and tell them to fold their papers over so their partner can't cheat. Maybe give candy to the winner of each pair to discourage cheating). --> 10 mins

Part 2 - That's quite different from
(1) Go through dialogue on the slides with students. Elicit meaning and discuss how western cultures see things differently etc. --> 10 mins
(2) Have SS circle the answers which they think fit together. Explain dialogue. Have SS practice dialogue together. --> 10 mins.

Part 3 - Blockbusters Game, Self explanatory.
