I am going to modify the assignment since the names are so regular.
All the vowels are just ㅇ+ the vowel. ㅐ&ㅔ are just ㅏ or ㅓ+ㅣ. There is no sense in writing those a bunch of times.
All consonants but three (ㅅ,ㄱ,ㄷ) follow the same patrern. To use ㅁ as an example: 미음.
The double consonants just have 쌍 (not to be confused with 짱, the first syllable of the noodle dish) meaning "double" or "twin" in front of them.
If this assignment seems useful to you, write three regular consonants, three double ones, and the three irregular ones three times. I trust you all with the vowels.
More regular progress should pick back up soon.
