In this week’s Apps Gone Free series, we are sharing with you four good apps you might want to try on your iPad. These apps are on sale today at least in the Canadian and American iTunes App Stores. Our favorite app in this collection is Visual Anatomy which we have reviewed in multiple posts in the past. Visual Anatomy is especially helpful for science teachers and students. It provides over 500 high resolution anatomy images with 3D rotational models to assist students in their learning of the human body. We have also included TableDrum which we think might be of some help to music teachers.
