Phones in class animation

Animation progress so far:

In this lesson I began to create my animation showing how phones should be used in class. Firstly I made an extra layer then I added a symbol for each drawing of the phones. When I had made each symbol and dragged the first one onto the background layer and added a keyframe at the beginning and the end, in the middle I added a motion tween motion and moved the image off the frame, I will do this with the rest of the symbols until I am pleased with my animation.

This is my animation, it was different than I hoped the end product to look like because I lost a couple of symbols. The animation is supposed to be giving out a message to say that you should not be using social networking sites online and it should always be on silent. What this animation misses is that phones can be useful at times, for example using a calculator on your mobile phone can be quicker and more effective. There is a print screen of the calculator above the animation which shows that it is supposed to be in the finished animation however I somehow lost it. 

Final animation:

Although I had a problem with losing my work I managed to get all the frames that I needed. In another lesson we were asked to make a soundtrack for the video therefore I have to make a YouTube video, here is the link.
