A.1 - Algebraic Expressions
A.1 The student will
a) represent verbal quantitative situations algebraically;
b) evaluate algebraic expressions for given replacement values of the variables.
- I can determine the total
cost of a family trip to the movies when the number of people and the cost of
tickets varies for each age group, and I can figure my total score on a video
game where different tasks give different points.
will always get the same result as everyone else when evaluating an expression
by following the set of rules called order of operations.
UNDERSTANDING THE STANDARD
2016 VDOE Curriculum Framework - AI.1 Understanding
· Mathematical modeling involves creating algebraic representations of quantitative practical situations.
· The numerical value of an expression depends upon the values of the replacement set for the variables.
· There are a variety of ways to compute the value of a numerical expression and evaluate an algebraic expression using order of operations.· The operations and the magnitude of the numbers in an expression affect the choice of an appropriate computational technique
(e.g., mental mathematics, calculator, paper and pencil).
The student will use problem solving, mathematical communication, mathematical reasoning, connections, and representations to
between verbal quantitative situations and algebraic expressions and equations.
practical situations with algebraic expressions in a variety of representations
(e.g., concrete, pictorial, symbolic, verbal).
algebraic expressions, using the order of operations, which include absolute
value, square roots, and cube roots for given replacement values to include
rational numbers, without rationalizing the denominator.
