Congruence with Transformations Math Games

3 games

In this series of games, your students will learn 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. The Congruence with Transformations learning objective — based on CCSS and state standards — delivers improved student engagement and academic performance in your classroom, as demonstrated by research. This learning objective directly references 8.G.A.2 as written in the common core national math standards.

Scroll down for a preview of this learning objective’s games and the concepts.

Concepts Covered

Two figures are considered the same if one can be superimposed on the other. Reflections, rotations, and translations, and compositions of these, are called rigid motions. Rigid motions preserve the measurements of angles. Terminology for transformations (image, pre-image, and preserve) is used to describe the effects of rigid motions and other transformations. Two figures in the plane are said to be congruent if they have the same shape and size.

Experiment with translations (sliding a figure in a particular direction for a particular distance), rotations (rotate around a particular point called the center of rotation), and reflections (flipping a point or figure over a particular line called the line of reflection). Use transparencies to experiment with rigid motions. Given two congruent images on a plane in different quadrants, use two transformations to superimpose the pre-image onto the second image. Verify what happens after a figure goes through different transformations.

Image for Wave Interference - Waves
Wave Interference - Waves Estimated Duration: 10 minutes Make waves with a dripping faucet, speaker, or laser. Adjust the frequency and amplitude, and observe the changes in the wave. Design experiments to measure wavelength and wave speed. Note: Students will automatically move through this simulation after 10 minutes of playtime.
Image for Wave Interference - Interference
Wave Interference - Interference Estimated Duration: 10 minutes Explore how a pair of wave sources create an interference pattern. Adjust the source frequency and separation, and determine how to change the interference pattern. Identify points of constructive and destructive interference by eye, and by using the detectors. Note: Students will automatically move through this simulation after 10 minutes of playtime.
Image for Wave Interference - Slits
Wave Interference - Slits Estimated Duration: 10 minutes Put up a barrier to see how the waves move through one or two slits, and discover the resulting interference pattern. Determine how to change the pattern by adjusting the slit width and separation. Predict the location of the interference maxima and minima, and verify your predictions. Note: Students will automatically move through this simulation after 10 minutes of playtime.
Image for Basketball Master
Basketball Master Estimated Duration: 12 minutes Shoot a basketball through the hoop and answer some questions along the way! The game does not have any instructional content, it simply has review questions spread throughout.
Image for Waves Intro - Sound
Waves Intro - Sound Estimated Duration: 10 minutes Make sound waves with a speaker, and hear the tone it produces. Adjust the frequency and amplitude, and observe the changes in the wave. Design experiments to measure wavelength and wave speed. Note: Students will automatically move through this simulation after 10 minutes of playtime.
Image for Robot Chef
Robot Chef Estimated Duration: 18 minutes Congratulations, you are creating the first all-robot restaurant in the city! As you serve more customers, you will be able to build more robots to assist in delivering tasty treats. Attend Night School and answer questions to earn advanced robot chefs!
Image for Wavebot
Wavebot Estimated Duration: 16 minutes Join Dr. Camila and Wavebot as they discover the effects of waves on their environment. Play through all 8 levels of this puzzle and compete for the high score!
Image for Earthquake!
Earthquake! Estimated Duration: 20 minutes How good are you at predictions? Can you figure out when—and how powerfully—an earthquake will hit Square City? Triangulation is the key!
