Straight-Forward App

As a homeschooling mother, I found this app to be a nice reinforcer to some of the concepts of animal classification I am teaching my first grader. It hits the major invertebrate groups and their important features. The app even teaches the name Cnidarian for jellyfish. I would suggest the app for elementary aged children. Also reading is not required, by touching the buttons next to the features, the app will read the information to the child.- A big plus so the child can do the app independently.
