ひとつ〜とお

Section 4 のみなさん、

スモール(small)さん asked me how to write hitotsu~tô in hiragana.

1　ひとつ
2　ふたつ
3　みっつ
4　よっつ
5　いつつ
6　むっつ
7　ななつ
8　やっつ
9　ここのつ
10　とお　(This is irregular. If you follow the rule, it is supposed to be とう.)

If you want to use hiragana tomorrow, go ahead! If you are not sure, you can add Roma-ji right next to hirgana so that you won't lose any points. ;)
