Showcasing projects on Congruence Transformations Showcasing projects on Congruence Transformations

I had made the commitment to teaching my 7th grade math students how to code.  I had chosen the tools and roughly mapped out the pacing for the year. It was time to dive in! The first unit my colleagues and I decided to attack was a geometry unit on Transformations.

  • CCSS.Math.Content.8.G.A.2 Understand that a two-dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them.
  • CCSS.Math.Content.8.G.A.3 Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates.

I started the kids on some programming exercises to find their way around the coordinate grid, drawing lines, and using colors. I hoped the early exposure to coordinate graphing would pay dividends later! I knew it would likely be…
