This week I’ve spent most of the time on transformations, so if students have explored the progression of lessons, they would hopefully by now have an understanding of what translations, rotations, reflections and dilations are, including properties. This means they understand the difference between rigid and non-rigid transformations, know the different properties about orientation, corresponding sides and angles, just to mention a few. Today’s two activities are basically practicing those properties in different ways. The first activity, Transformations – Where Am I Now? focuses on applying the properties of transformation (both rigid and non-rigid) in a coordinate grid and determining coordinates of transformed images, based on a specific transformation and directives. The second activity, Transformations – How Did I Get Here?, is using the properties of transformation to determine WHAT combination of transformations were done to map a preimage onto a given image, and also things like finding the line of reflection or the point of dilation, all of which require an understanding of the properties of transformations.
Here is the link to the two activities and the one video that gives an overview of both.
