We've also started by diving in head first and quickly going through everything we've learned before, while sprinkling some new words in there just for fun. I was happy I remembered more hiragana than I thought I would, but I should have remembered more. So I have been doing lots of lines to help reinforce it in my brain:
In addition to hirigana, we worked on numbers. But not just numbers, we worked on numbers for counting things (because those two things are different in Japan). You pronounce a number differently when you are giving someone your phone number than when you are telling a person who many cats you have. Fun times!
I've been able to get a couple hours of studying and writing things down over and over and over again so I'm really happy about it. Tomorrow's study session will be awesome!
