BIG IDEAS:
(Content standards, assessment anchors, eligible content) objectives, and skill
focus)
Numbers, measures, expressions, equations, and inequalities can
represent mathematical situations and structures in many equivalent
forms.
M11.A.1.3.1 Compare and/or plot irrational numbers at the
approximate location on a number line.
M11.A.3.1.1 Simplify expressions using the order of operations
to solve problems (any rational numbers may be used).
M11.D.2.1.1 Solve compound inequalities and/or graph their
solution sets on a number line (may include absolute value
inequalities).
M11.D.2.1.3 Write and/or solve a linear equation from given
problem situations.
