This lesson is originally from eatyourkimchi.com on How to talk about your vacation.  I modified it a little and attached a worksheet.

The worksheet was actually a challenge for my students so, I didn't get to do the second page. The second page might be a bit hard for 1st graders, but this lesson can be used for all three levels. You may want to get a crossword or do a game if your students happen to be faster than mine.

 I also showed a video of my vacation which took up some time. Remember to check the slides.
