CCSS.Math.Cont.6.RP.A.1 ( Grade 6 ): Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities.

CCSS.Math.Cont.6.RP.A.2 ( Grade 6 ): Understand the concept of a unit rate a/b associated with a ratio a:b with b is not equal to 0, and use rate language in the context of a ratio relationship.

CCSS.Math.Cont.6.RP.A.3b ( Grade 6 ): Solve unit rate problems including those involving unit pricing and constant speed.

CCSS.Math.Cont.7.RP.A.1 ( Grade 7 ): Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units.

CCSS.Math.Cont.7.RP.A.2a ( Grade 7 ): 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.

CCSS.Math.Cont.7.RP.A.2b ( Grade 7 ): Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.

CCSS.Math.Cont.7.RP.A.2c ( Grade 7 ): Represent proportional relationships by equations.

CCSS.Math.Cont.7.RP.A.2d ( Grade 7 ): Explain what a point (x, y) on the graph of a proportional relationship means in terms of the situation, with special attention to the points (0, 0) and (1, r) where r is the unit rate.

CCSS.Math.Cont.7.RP.A.3 ( Grade 7 ): Use proportional relationships to solve multistep ratio and percent problems.

CCSS.Math.Cont.8.EE.B.5 ( Grade 8 ): Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways.

CCSS.Math.Cont.K.G.A.1 ( Kindergarten ): Describe objects in the environment using names of shapes, and describe the relative positions of these objects using terms such as above, below, beside, in front of, behind, and next to.

CCSS.Math.Cont.K.G.B.4 ( Kindergarten ): Analyze and compare two- and three-dimensional shapes, in different sizes and orientations, using informal language to describe their similarities, differences, parts (e.g., number of sides and vertices/“corners”) and other attributes (e.g., having sides of equal length).

CCSS.Math.Cont.K.G.B.5 ( Kindergarten ): Model shapes in the world by building shapes from components (e.g., sticks and clay balls) and drawing shapes.

CCSS.Math.Cont.K.G.B.6 ( Kindergarten ): Compose simple shapes to form larger shapes.
