## Ratey the Math Cat Common Core Standards

Standard | Standard Description |

6.RP | Understand ratio concepts and use ratio reasoning to solve problems. |

6.RP.1 | Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. |

6.RP.2 | Understand the concept of a unit rate a/b associated with the ratio a:b with b not equal to 0, and use rate language in the context of a ratio relationship. |

6.RP.3 | Use ratio and rate reasoning to solve real-world and mathematical problems, e.g. by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations. |

7.RP | Ratios and Proportional Relationships |

7.RP.1 | Compute unit rates associated with ratios and fractions, including ratios of lengths, areas and other quantities measured in like or different units. |

7.RP.2 | Recognize and represent proportional relationships between quantities. |

7.RP.3 | Use proportional relationships to solve multistep ratio and percent problems. |

8.EE.5 | Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed. |

8.F.2 | Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). For example, given a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change. |

8.F.4 | Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values. |
