Describe a ratio
Describe how two quantities compare using an ordered pair of multiplicities.
Complete a ratio table
Scale both quantities by the same factor and organize equivalent pairs.
Find a unit rate
Divide both quantities to find an amount for one unit.
Find a percent of a quantity
Connect percent, fractions with denominator 100, and multiplication.
Divide fractions
Interpret fraction division through measurement and reciprocal multiplication.
Find a GCF or LCM
Analyze factor and multiple structure without relying on isolated lists.
Compare signed numbers
Use position and context to compare positive and negative quantities.
Interpret absolute value
Separate a number's direction from its distance to zero.
Plot in four quadrants
Interpret signs as horizontal and vertical directions from the origin.
Evaluate whole-number exponents
Interpret an exponent as repeated multiplication of equal factors.
Evaluate a variable expression
Substitute a value while preserving grouping and operation order.
Solve a one-step equation
Use inverse operations while maintaining equality.
Represent an inequality
Connect a boundary, strictness, and direction to infinitely many solutions.
Find polygon area
Split triangles and quadrilaterals into familiar area models.
Reason about prisms
Connect nets and layers to surface area and rectangular-prism volume.
Describe a distribution
Use center, variability, and shape together to describe numerical data.
