| |Unit : 3 Slope | |

|Grade Level: 8th grade |Essential Questions: How does slope relate to unit rate? How do slopes of proportional relationships |Suggested Days: 15 |

| |relate to one another? How can you use similar triangles to verify the slope of a line? How is the | |

| |equation y=mx derived? How is the equation y=mx+b derived? What are the differences between linear and | |

| |non-linear functions? | |

|Vocabulary: | |

|Constant of variation |Mathematical Practices: Highlighted practices to be assessed. |

|Direct variation |1. Make sense of problems and persevere in solving them. |

|Linear equation |2. Reason abstractly and quantitatively. |

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

|Slope-intercept form |4. Model with mathematics. |

|Point-slope form |5. Use appropriate tools strategically. |

|Standard form |6. Attend to precision. |

|x-intercept |7. Look for and make use of structure. |

|y-intercept |8. Look for and express regularity in repeated reasoning. |
