Adapted slightly from some of the other materials on here. Thanks to the contributors.
I've included a 4 corners game on both slides as depending on time and how the class ran would depend on which class it was used in. If you have less time you can make it a sitting exercise - split the class into teams, the team guess a number, writes it down, if it matches the one you select they get a point.
The dialog vocabulary has lots of Korean translations as my Grade 2's are lower level.
For the dialog activity, set a timer of around 5/6 mins depending on the level of your class. When they finish bring it up to you, write the order number they finished in then dish them out again to mark.
