Hands-On Geometry

Time and Place

Monday-Tuesday, June 26-27
9:00 a.m. to 3:30 p.m.
at the Head-Royce School in Oakland, CA


In this two-day workshop for teachers in grades 6-10, I will present kinesthetic and manipulative activities. This hands-on curriculum is intended to complement related work in paper-pencil environments: it serves to preview, review or extend key concepts in geometry. The activities can be used to enrich and enliven the high school geometry course, or to lay the groundwork for it.

  • Topics include angles, triangles, quadrilaterals, area, the Pythagorean theorem, congruence, similarity, "soccer angles", and tiling.
  • Tools include manipulatives (such as pattern blocks and geoboards) and puzzles (such as tangrams and pentominoes.)
  • Technology will be used to illustrate concepts.

These lessons were developed in somewhat heterogeneous classes, and reach a wide range of students. They provide support for the less visual by complementing the drawing and studying of figures, and enrichment for the more talented by offering deep and challenging problems. 

Guest presenter: Rachel Chou. 

This workshop does not overlap with Transformational Geometry.

I am happy to offer a workshop on Hands-On Geometry to your school or district. Contact me.
