I'm not sure how many people are using these Dong-ah books, but I'm teaching 3rd and 4th grade with them and thought I'd upload some of my materials in case it can be useful. Basically I'm just tweaking material from other textbooks on Waygook, so a big thank you to the original posters.

You can sign up on the Dong-ah website with your co teacher's help and access the e-book and other materials. Here is the web address: http://www.douclass.com/

Chapter 1: Hello. My Name is Cindy
Key words/expressions PPT (from the douclass website)
Fast Reading PPT (I use this activity as a warm up for every lesson to drill vocab and translation. The students tend to enjoy it. The PPT is split into 3 sections: 1st, say the English word and then the Korean word as it appears. 2nd, say the Korean word while looking at the English word. 3rd, say the English word while looking at the Korean word).
Bingo Words (Listening game)
Who's Behind (Speaking Game)
Pass the Ball (Speaking Game)
Mission Impossible (Writing Game)

Again, all these PPTs are taken and tweaked from other posters, so a big thank you to the original posters!
