By Hand and Eye
Jim Tolpin and George Walker, along with Lost Art Press publisher Chris Schwarz, have made By Hound and Eye and From Truths to Tools free downloads to folks who will use them with kids and students.
By Hound and Eye is a workbook with great layout and design exercises that can easily be adapted for distance learning. From Truths to Tools covers basic historic layout tools, many of which are still used in the trades, and makes the linkage between the tools and the mathematical truths behind them. Again, each chapter can make a good distance learning exercise.
The Sector and the Scale of Chords are two great tools that “teach how Geometry was used by builders through human history.” All you need are a pencil, paper, compass, and a straightedge.
If you go to Jim and George’s website and e-mail them, they are happy to share free downloads of their pamphlets about these tools, as well as their paper templates, with folks doing “homeschooling.” Homeschooling Page
French’s Mechanical Drawing
The Applied Geometry Exercises from French’s Mechanical Drawing are timeless. These were written in 1911 and a version of the book is still in use.
