Aligned Standard

M.EE.6.RP.1: Demonstrate a simple ratio relationship.

Grade Level Standard

This is aligned with the following California State Standards:

  • 6.RP.1 - Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. For example, The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak. For every vote candidate A received, candidate C received nearly three votes.

Linkage Level Descriptions

Initial Precursor

Communicate understanding of a unit by recognizing a group of countable objects. Communicate understanding of wholeness by recognizing an object that has all the parts joined together. Recognize parts of an object and the whole object.

Distal Precursor

Recognize two glasses with an equal amount of liquid.

Proximal Precursor

Divide familiar shapes, such as circles, squares, and/or rectangles, into two or more equal parts. Demonstrate understanding of a unit fraction (e.g., 1/4) as the quantity formed by one part when a whole is partitioned into n (e.g., 4) equal parts. Recognize a fraction as a number expressed as a quotient of two integers in the form a/b, with b not equal to zero.

Target

When shown two groups of objects, one group with one object and another group with multiple objects (e.g., 4), recognize that there are four times as many objects in the second group as in the first group. When shown two groups of objects, one group with one object and another group with multiple objects (e.g., 4), represent a many-to-one ratio of the parts as 1:4 or 1/4.

Successor

When shown two groups of multiple objects (e.g., one group with two objects and another group with three objects), recognize that for every a objects in the first group there are b objects in the second group (e.g., for every two objects in the first group, there are three objects in the second group). When shown two groups of multiple objects, represent a many-to-many ratio of the parts (e.g., 2:3).
