I love the football ppt and will be using it.

Here is my lesson plan for Part 1, Prepositions of Place powerpoint, and a Memory game that I modified from my 5th Grade lesson last year

I used this last year to teach prepositions:  in, on, under, over, in front of, behind. 
My students looooved it as it keeps going faster and faster.  Check out the hand movements at the end.  If you teach them the movements and the song and then doing it together it can take quite a few mins of lesson time.

Here are my lesson plans for Parts 3 and 4
We are going to make a mini-book with prepositions that I found on the fifth grade thread from last year
Attached is the ppt to show how to make the book and a word file to print out the template - you may want to change "beside" to "next to" if you have been using the We Are Busy Beavers song

Here is a worksheet with vocabulary, key sentences, listen and speak 1 & 2, Story Time, Bingo game, and a wordsearch. The vocab and key sentences also have the Korean. For homework they must write their vocab and key sentences 3 times. If they did then the next class we can play the bingo game.
Also I have made a New Words PPT. For each slide,  we practice saying the new word. Then the Korean meaning comes up. Then a sentence that the words goes in.
Hope you find all this helpful. There are so few resources with this book.
