As an agriculture teacher I find this app an asset to the teaching toolbox because there will be many days I will be gone and need to keep my students on track. This app would easily allow me to record my lesson and have the sub play it for the students. The interactive abilities that come with it make it easy for my students to know what to do, when. This also makes it harder for students to get behind on work when they have missed because they were sick or for extra-curricular activities. Another go to use for this is when students need to present an idea. They could record it and submit it anytime. This is a free app you can get through iTunes. I see this app being useful for students of all ages grades first through twelfth.
