Hello there,
Just thought I'd upload some materials but the links for my textbook aren't active yet.
This is the for the 천재교육 book, where the author is actually 이재희, not Judy Yin. I'm attaching a picture of the textbook to this post too.
Anyways, I made a review PPT for lessons 2-6 and edited a Kung Fu Panda bomb game from lessons 2-7. My kids are being tested before the semester ends so I thought this might be the case for a lot of other people too. The game isn't mine, so credit to whoever made the game! The review PPT is largely my own, save a lesson here or there. Enjoy :)
