Adding detail to my story

I am learning to add detail to my story like What,Why,Where,Who,When,How.  I use It In my story to make It more interesting.  For example, I said we did 2 hours of badminton in my story.  I told the reader how long we played badminton for.  It is tricky to remember full stops.  I am proud of remembering to use capital letters.  Next I want to work hard at remembering to use full stops.
