Graphing Parabolas

12 08 2013

A friend showed me a photo of them on a wave in Fiji. I instantly saw an application of the topic of Graphing Parabolas for Year 10 so I prepared the following sheet. I rotated the photo so the parabola was essentially aligned with the y – axis. 

My instruction to the class was to find the equation of the parabola. Most of the students decided to draw the parabola over the grid. One group worked out the equation and opened Geogebra to check their result.

Another group drew the grid over the wave and then worked out the equation.

The flexibility of approaches and engagement in the lesson was wonderful to see.
