Resources
There are many links on the Schedule page.
Geometry Labs
Much of the work we will do is based on my book Geometry Labs. I did not include a handout in the packet for every activity drawn from the book. Geometry Labs includes many more labs than I have time for in the workshop, plus answers and abundant teacher notes about all the labs. It is available for free download on my Web site. The site also includes corrections, extensions, and suggestions from users of the book.
Angles: Chapter 1
Puzzles: Chapters 2, 4
Polygons: Chapter 3
Symmetry: Chapter 5
Triangles and Quadrilaterals: Chapter 6
Tiling: Chapter 7
Area: Chapter 8
Pythagorean theorem: Chapter 9
Similarity and Scaling: Chapter 10
Henri Picciotto’s Math Education Page
Some of the work will be based on material that is available elsewhere on my Web site. On some of those topics, there are many more documents available on the site than you have in your packet. You'll also find teacher notes, some answers / solutions, and pedagogical / philosophical comments. Relevant pages for additional materials and ideas:
Geometry Labs Template documentation
General
Special papers
Angles
Blank "pie chart" worksheets, and a GeoGebra file to make your own blank pie charts.
Symmetry home page (includes a unit for grades 4-6, parts of which would be great for middle school)
Geometric puzzles home page (especially pentominoes and supertangrams)
Not exactly geometry, but hands-on and visual: Fraction Arithmetic on Grid Paper
See also the GeoGebra page on this site.
If you'll be teaching a high school geometry course
Urban School’s Math 2 (when I worked there)
See also Transformations for transformational proof
Cutting a rectangle, rearranging the pieces to make a square: solution in two cuts, three pieces
Working with Pentominoes
by Henri Picciotto
Available from Didax. Includes an interactive DVD of the whole book which allows you to project any page, solve puzzles on-screen, search, and more.
