Most material for building should be items found outside or imagined for drawing ideas or blueprints.  Other tools need may include rope, duct tape, cardboard and cutting tools.

Also, a journal or scrapbook! We're going to spend the summer building the most amazing forts so we want to make sure we have somewhere to help hold onto the ideas and memories. 

It would also be nice for each student to have a way to document their week's build with either pictures or video.

Saws, hatchets and knives are obviously very useful for cutting old branches to size and stripping leaves, but we all vary in terms of what equipment we have, what we allow our children to use (dependent of course on age and exposure) and under what level of supervision.  Please assess your child's level and what tools you feel the students can or cannot use.
