Design Thinking: The Hippo Roller

I saw this on Facebook and harked back to my PD on design thinking. The cation to it was "Your idea doesn't have to be complicated to be used". A new invention that fits the needs of a situation and makes beneficial impact. A great clip to show as an example of how thinking a little different and not necessarily more complicated can successful.

Pattern of Transformations in one lesson....Achieving the impossible!

This year we are using a new resources. It approaches and orders concepts differently than previous years. So far we have looked at linear, inverse, exponential and started looking at quadratic. The first year using a new resource always throws up its own set of little hurdles. Todays hurdle was teaching transformations in a cramped timeline.

The class started by revising homework and reviewing the types of functions we have seen and introduce the idea of a parent function.

Here we reviewed the characteristics of linear, quadratic, reciprocal, absolute and square root functions.

Each student got a blank table and series of graphs, by which they were to come up with some generalizations about how changes in the equation generated transformation of the graph. I asked them to color each function differently to make the sheet less overwhelming and draw their eyes to the transformation.

This lesson worked best when all parts of the lesson were done. It was a two part lesson where the introduction and graphing was done in one (sent away to come up/finalize generalizations). Then start the next with compare and share and move into transformation of quadratic a in turning point form. 

Overall worked well :)

Pythagoars Pile Up

I have seem the Trigonometry Pile Up activity sheet many times and stumbled upon this adaptation for Pythagoras. Its called Pythagoras Pile Up by Jan Litchenberger. Great way to practice the skills and develop visual interpretation.
