Using All the Angles in Ninth Grade Geometry

The geometry balloon project described in this video was an exciting task that drew upon at least five core curriculum areas: surface area, volume, right triangle trigonometry, polygons and proportion.

The project certainly involved some 21st century technologies, as students used the multiple award-winning Geometer's Sketchpad software, and then transferred data to Inkscape, an illustration tool that can be used with our laser cutter. Students used the laser cutter to cut out all the polygonal panels to exact sizes.

The students then constructed the projects in the IdeaLab, and sometimes in the Upper School art room. This final step makes this a good example of the Strategic Vision goal to rethink space, as students divided their time between their regular classroom, the IdeaLab and the art room.

We encountered challenges along the way, but these enthusiastic ninth graders persevered to success.

Also, in this topic we again talked about the multicultural roots and examples of geometric art and architecture throughout the world, with particular mention of Islamic art, which focuses on geometric shapes with spectacular results, as in the Alhambra, in Granada, Spain.
