8th Grade High School Mathematics I: Relationships between Quantities

Reason quantitatively and use units to solve problems.

M.1HS8.1

Not covered
Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays.
(Content unavailable)

M.1HS8.2

Not covered
Define appropriate quantities for the purpose of descriptive modeling.
(Content unavailable)

M.1HS8.3

Not covered
Choose a level of accuracy appropriate to limitations on measurement when reporting quantities.
(Content unavailable)

Interpret the structure of expressions.

M.1HS8.4

Interpret expressions that represent a quantity in terms of its context.

M.1HS8.4.a

Not covered
Interpret parts of an expression, such as terms, factors, and coefficients.
(Content unavailable)

M.1HS8.4.b

Not covered
Interpret complicated expressions by viewing one or more of their parts as a single entity. For example, interpret P(1 + r)^n as the product of P and a factor not depending on P.
(Content unavailable)

Create equations that describe numbers or relationships.

M.1HS8.5

Not covered
Create equations and inequalities in one variable and use them to solve problems. Include equations arising from linear and quadratic functions and simple rational and exponential functions.
(Content unavailable)

M.1HS8.6

Partially covered
Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.

M.1HS8.7

Partially covered
Represent constraints by equations or inequalities, and by systems of equations and/or inequalities, and interpret solutions as viable or non-viable options in a modeling context. (e.g., Represent inequalities describing nutritional and cost constraints on combinations of different foods.)

M.1HS8.8

Not covered
Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations. (e.g., Rearrange Ohm’s law V = IR to highlight resistance R.)
