I just changed most of the questions, updated some and kept a few. Also updated the worksheet notes and put them on the slides too.
I tried the original but it was too difficult for my students - several only got one correct. With this one at least half the class could get half the answers right.
I used it as a short introduction to the grammar but use it as you like.
I just had them write the answer to the Powerpoint questions individually on the worksheet (Japanese OK) and then showed the answer on the TV.
Slide 15 is specific to me so you may want to change it.
Thanks to the original uploader.
