2nd meeting with my German Partners (1)

I and my husband got German partners who are cute teenagers.
I'm going to organize the topics and contents that we talk about at the meeting whenever we meet. I will publish a post to include one topic. In other words, each post will have one topic because I don't have enough time to create a long post. I don't want to get any burden to create a post for this blog. If so, I will stop writing something for this blog. I think that is not good.

So, I will talk about 'numbers' in this post.

Actually, we had A2 German test yesterday. So, we talked about it at first. And I told them listening is the hardest part of it and I was so confused when I dictate numbers.
So, we practice to dictate numbers including phone numbers and time in German.

26 (sechsundzwanzig)
80 (achtzig)
110 (einhundertzehn)
.
.
.

0124667898 (null ein zwei vier sechs sechs sieben acht neun acht)
.
.
.
I am so confused when they say same numbers in a sequence.

And the time is worst part for me.
9.25 (fünf vor halb zehn)
8.45 (vieltel vor neun)
9.15 (vieltel nach neun)
9.45 (drei vieltel nach neun)
.
.
.

And then I taught Korean numbers too. They already knew it, but it's hard to memorize all. Now, I feel like Korean is difficult. I should have taken the course for getting Teaching Korean Certificate in Korea. I missed the opportunity. But, at least, I have a chance to teach Korean and study how to teach Korean. I'm happy with that. :)
Anyway, I arranged numbers and two way to call them like below.

Orange: just like names of numbers
Green: counting (ex: one ball - 공 하나, two balls - 공 둘)
Blue: counting days (ex: after one day - 하루 뒤, two days ago - 이틀 전)

I will talk about counting days more when I have time. :)
