The kids at home were required by their Reading teacher to read at least 3 stories from their book for the entire month of September.
You bet my own kid was all picky when it comes to reading long and short stories. So, to encourage him to read, I let him pick the story that he likes best to make reading more pleasant.
And, if in case, he just want short stories, I let him pick 2 - 3 stories to compensate for the short selections. Further, after the reading, we ask questions to make sure that he has understood what he has read.
But, giving your child perks after a home reading can encourage more until he gets the habit of reading without being told.
