Ratio Notation and Relationships

CONCEPTUAL

Mathematics›Ratio & Proportion|Ages 12—14|ID: mt_yK51ZnKA8m

Understand that a multiplicative relationship between two quantities can be expressed as a ratio; use ratio notation; simplify ratios

Mastery Evidence

Explain why 'for every 2 red beads there are 5 blue beads' can be written as 2:5 or as 2/5 of the blue count
Identify the multiplicative relationship in a table of values (e.g. y is always 3 times x)
Connect the ratio a:b to the fraction a/b and to the linear function y = (a/b)x

Assessment Prompt

“Can [child] explain why a ratio like 3:4 is really the same as the fraction ¾ — and show how that relationship connects to a straight-line graph through the origin?”

Curriculum Standards5 alignments

7.RP.2Common Core State Standards for Mathematics

Recognize and represent proportional relationships

Recognize and represent proportional relationships between quantities.

7.RP.2aCommon Core State Standards for Mathematics

Decide whether two quantities are in a proportional relationship

Decide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin.

7.RP.2cCommon Core State Standards for Mathematics

Represent proportional relationships by equations

Represent proportional relationships by equations. For example, if total cost t is proportional to the number n of items purchased at a constant price p, the relationship between the total cost and the number of items can be expressed as t = pn.
