MGSE9-12.N.Q.1 Use units of measure (linear, area, capacity,
rates, and time) as a way to understand problems:
a. Identify, use, and record appropriate units of measure
within context, within data displays, and on graphs;
b. Convert units and rates using dimensional analysis
(English-to-English and Metric-to-Metric without
conversion factor provided and between English and
Metric with conversion factor);
c. Use units within multi-step problems and formulas;
interpret units of input and resulting units of output.
MGSE9-12.N.Q.2 Define appropriate quantities for the
purpose of descriptive modeling. Given a situation, context, or
problem, students will determine, identify, and use appropriate
quantities for representing the situation.
MGSE9-12.N.Q.3 Choose a level of accuracy appropriate to
limitations on measurement when reporting quantities. For
example, money situations are generally reported to the
nearest cent (hundredth). Also, an answers’ precision is
limited to the precision of the data given.

MGSE9-12.A.SSE.1 Interpret expressions that represent a
quantity in terms of its context.
MGSE9-12.A.SSE.1a Interpret parts of an expression, such as
terms, factors, and coefficients.
MGSE9-12.A.SSE.1b Given situations which utilize formulas
or expressions with multiple terms and/or factors, interpret the
meaning (in context) of individual terms or factors.
