Canon has gone all out to produce the most impressive collection of paper craft printables I've ever seen. Your students will absolutely love them.
The premise is simple: First, you select from one of the categories such as art, architecture, transport, fantasy or my personal favourite craftown that allows you to print out templates for items to make an entire paper city.
Next, print out the template and instructions.
Then, Construct. Some are very simple and others are quite complex but each one is rated for difficulty so you can decide what to to attempt and leave out.
Finally - You could work these into an art lesson, a maths lesson about 2D and 3D shapes, or even use them as props in a digital animation. You are only limited by your imagination.
Please take a look at Canon's Paper Crafts today as it won't disappoint and best of all it's free.
