Here is the lesson I used for my grade 2 middle school class, lesson 6. This is what I did....
Warm up: Review what I did last lesson (weather lesson)
Engage: Talk to students about grammar by showing the sentence structure and explaining what kind of verbs (infinitive verbs: Dongsa Wan-hyeong).
Read the listen and number section and pause after each number to ask if they might have better opinions (works really well with my classes).
Say the correct order using the slides (just look at the slides).
Study: Talk to students about what they think they should do for the different situations (slides 11-15). Slide 11: if you push the button you get tons of money, but someone in the world will die. Slide 12: Your mother and boyfriend/girlfriend are drowning. Slide 13 & 14: Questions are on the slide, but ask students what they would do if the plane went down and they could only grab 2 things. Slide 15:It is stormy outside and the bus isn't coming. You have room to help one of these 3 people (the old lady, your best friend of the girl of your dreams)
Activate: Worksheet using fill in the blanks. After reviewing the worksheet show pictures from the slide show and ask students what they should do and why.
I originally used keynote so the transitions in the ppt. file might need to be adjusted.
