Transformation Math Games - Translation, Rotation, Reflection Games: Recognize motion as a slide (translation), turn (rotation) or a flip (reflection)
This visually challenging game helps students understand congruence through translation (slides), rotations (turns), or reflections (flips). At the beginning, when the board is completely open and no squares have been filled in the game doesn't appear to be too difficult. After all, we're just filling in patterns of squares, right? Well, as players keep filling in the board, it's more and more challenging to find ways to slide, turn, and flip the available shapes to fit the remaining blank squares. Some of the most mind-bending are the rotations. They're not obvious at all and it sometimes takes quite a bit of mental gymnastics to figure out if something really will fit.
Common Core Mathematical Standards
8.G.1 Verify experimentally the properties of rotations, reflections, and translations.
8.G.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.
8.G.3 Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates.
