Pantry Dilations
I noticed that many snacks in my pantry showed dilated images of the food on the packaging. After snapping a few photos myself, and gathering feedback from folks in the #MTBoS on Twitter, this resulting activity provides students with some unique measurement opportunities. Additionally, Desmos sliders help students visualize dilations to informally test their scale factors (thanks to Dave Johnston for the suggestion). This is a less formal introduction to the concept of dilations in the coordinate plane. Math and food - what more can one ask for? :-) Looking for dilations activities with consideration for specific coordinates?
