Lesson plan based on a hinged dissection
Breaking Away from the Mathbook: Creative Projects for K-8
Pat Baggett and Andrzej Ehrenfeucht have posted a lesson plan based on the
swing-hinged dissection of the equilateral triangle to the square.
Triangle to square: A hinged dissection
I especially like the way the hinges are incorporated into the design,
using the thick foam rubber that makes up the pieces. Nifty!
And the animations on the webpage are really effective, too.
Student activities based on the book
Kearsarge Regional Middle School
April 2003: Every spring, Kim Sharp,
a middle school mathematics teacher,
designs a project called "Geometry Playtime" in which each student
in his pre-algebra class builds a model, a game,
or a display of some geometric curiosity. The 6th graders
are then invited over to view the results.
After reading my book,
Kim decided to have the projects in 2003
be based on hinged dissections of squares.
