Write About the Math
How do reflections help the game designer create a balanced, symmetric level?¿Cómo ayudan los reflejos a la diseñadora del juego a crear un nivel equilibrado y simétrico?
Say your answer to a partner first. Then write it, using at least two of these words:
Model: Reflecting over the y-axis changes the ___ coordinate because ___. — Student states reflecting over the y-axis flips the sign of the x-coordinate while the y-coordinate stays the same, so (3,2) becomes (-3,2).
