Almost. There are a few possible variations, but I would say:
"By the end of the class, I would like to see how well each of you has made a good butterfly to show to the other teachers."
Although there are many small changes, most are only to make the sentence run smoothly and sound natural to an English ear. The main alteration is the tense: by the end of the class, hopefully, the butterflies will be freshly-made and the manufacture can be referred to in the present perfect.
