|Unit of Instruction||Proportionality, Ratios, and Rates|
Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities.
Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0, and use rate language in the context of a ratio relationship.
|Learning Targets and Learning Criteria|
• understand that a ratio is an ordered pair of non-negative numbers, which are not both zero.
• explain the relationship that a ratio represents.
• create multiple ratios from a context in which more than two quantities are given and conceive of real-world contextual situations to match a given ratio (equivalent ratio tables, tape diagrams, double number line diagram).
• write a ratio that describes a relationship between two quantities.
• define the term “unit rate” and demonstrate my understanding by giving various examples.
• recognize a ratio written as a unit rate, explain a unit rate, and give an example of a unit rate.
• describe the ratio relationship represented by a unit rate.
• convert a given ratio to a unit rate.
• recognize that I can associate a ratio of two quantities, such as the ratio of miles per hour is 5:2, to another quantity called the rate.
• given a ratio, identify the associated rate, and identify the unit rate and the rate unit.
• given a rate, find ratios associated with the rate, where the second term is one and a ratio where both terms are whole numbers.
• recognize that all ratios associated to a given rate are equivalent because they have the same value.
This week we are starting our Ratio Unit and will be focused on practicing the concepts in class using IXL, Mathspace and worksheets as well as taking notes and completing notebook activities.
We did start a new unit this week, there are no homework assignments. We are mostly taking notes and completing class work.
Upcoming Assignments: Due Friday, December 15 “Ratio/Unit Rate Homework”
TEST ON FRIDAY DECEMBER 15 Equivalent Ratios and Unit Rates
Students are able to complete additional practice on both MathSpace and IXL
