Below you will find the answer key as well as three versions of this Fish Anatomy Labeling worksheet to allow for differentiated instruction or teaching different grade levels. I used the tracing words with kindergarten, then first and second grade used the cut and paste version, but if you prefer not to use scissors and glue there is a version where they can write the labels.This took us about 30 minutes, depending on the class, and I did it with my kindergarten, first, and second grade classes
