This book would be appropriate for most classrooms from 1st to 3rd grade. The little girl in the story, Sophie, falls asleep and dreams about a garden. This takes my mind a few different ways for lessons because there are a few things I could cover. The first thing to come to mind is letting the children draw out their own happy place and asking them to write a short summary about why they would consider it their happy place. I would let them share this with the class. Another lesson idea could be repetition or sequencing. The little girl keeps exploring finding one thing after another. Each time she finds something new she says the same thing, "Somebody will be looking for this!"
