| |Unit 7: Transformation on the Coordinate Plane | |

|Grade Level: 8th grade |Essential Questions: How would you describe the differences among translation, rotations, rotations, |Suggested Days: 14 |

| |reflections, and dilations? How can you determine what transformation was performed by analyzing the| |

| |original set of points and the points of the transformed figure? What connections exist between | |

| |transformations and congruence? | |

|Vocabulary: | |

|Correspondence |Mathematical Practices: Highlighted practices to be assessed. |

|Congruent figure |1. Make sense of problems and persevere in solving them. |

|Transformation |2. Reason abstractly and quantitatively. |

|Inage |3. Construct viable arguments and critique the reasoning of others. |

|Translation |4. Model with mathematics. |

|Reflection |5. Use appropriate tools strategically. |

|Rotation |6. Attend to precision. |

|Center of rotation |7. Look for and make use of structure. |

|Similarity transformations |8. Look for and express regularity in repeated reasoning. |

|Congruence transformations | |

|Dilation | |

|Center of dilation | |

|Scale factor | |
