Jack McKee is a builder/designer who started volunteering in the schools when his kids were in school.
"Much to my surprise kids were appreciative of the hands on activities I did (many copied from old science books) and I went on to teach woodworking and science for the city Parks Department. Parents and teachers kept asking about both woodworking and my set of Builder Boards so I wrote two books: Woodshop for Kids and Builder Boards," writes McKee on his website www.woodshop4kids.com.
McKee's YouTube page also includes videos on builder boards and other projects.
