===== 例文 =====

For each of these examples below, an English translation is provided in a hidden box.

    * ++answer | That teacher gives out homework every time there's class.++

==== 数量詞 ====

    * ++answer | Each page of this book is interesting.++
    * Note that <wrap fg=royalblue>ページ</wrap> is not a time or distance, so おきに cannot be used.
  - 電車が１０<wrap fg=royalblue>分</wrap>__ごとに__くる。
    * ++answer | The train comes every 10 minutes.++
  - 電車が１０<wrap fg=royalblue>分</wrap>__おきに__くる。
    * ++answer | The train comes every 10 minutes.++

===== 以外 =====

One exception to note for <wrap fg=royalblue>数量詞</wrap> is that ごとに and おきに have different meanings in the case of talking about 1 of something.

  * １年__ごとに__  = one time in one year
  * １年__おきに__ = one time in two years 

Presumably this is because おきに implies that the instance lasted for a year? I'm not sure. FIXME
