Here's what I have been doing for Grade 3, Lesson 7. I have some slides from my vacation that you might want to remove, or swap out for your own. I just wanted to tie in the theme of "Finding Korea Around the World!"
My Grade 3s are doing speaking tests after the break. For the speaking tests, I'm having them choose one thing about Korean culture to talk about, so we've been spending a long time on the worksheet, editing and practicing.
I haven't gotten to the telephone game portion of it yet. I have played this version with other classes, though, and I will have to warn you that while fun, it is kind of a nightmare to score! If you do go ahead and play it, it might be useful to get your co-teacher involved on scoring this one.
