Can you say what I did in my last vacation

[Nena Tamayo Valverde]

Hi, I need help with this question: Can you say what I did in my last vacation. I'm asking this because I wrote an essay for my daughter (13), she's taking english at school, and the title was "What I did on my last vacation", because she's learning how to use the past tense, and her teacher told her that the title was wrong, that it should be "What I did in my last vacation".

Hello Nena

There are three possible prepositions for that context. The first one is more common than the others:

1. on my vacation
2. during my vacation
3. in my vacation

Hope that helps.
