This term the year 8 DT class will be creating their own character designs to be used on a childrens activity pack. To introduce them to this design software I have put together a short clip on using the basic tools in Pixelmator, such as working with layers, paint bucket, magic wand, shapes and adding text.
This is a great piece of software to use as an alternative to the pricey Photoshop.
Pixelmator also have a large number of tutorials on their website which pupils could also view. http://www.pixelmator.com/tutorials/#basic-tutorials
