Algebraic reasoning. The student applies mathematical
process standards to develop concepts of expressions and equations. The student
is expected to:

(1) represent multi-step problems involving
the four operations with whole numbers using strip diagrams and equations with
a letter standing for the unknown quantity;

(A) represent problems using an input-output
table and numerical expressions to generate a number pattern that follows a
given rule representing the relationship of the values in the resulting sequence
and their position in the sequence;

(B) use models to determine the formulas for
the perimeter of a rectangle (l + w + l + w or 2l
+ 2w), including the special form for perimeter of a square (4s)
and the area of a rectangle (l x w); and

(C) solve problems related to perimeter and
area of rectangles where dimensions are whole numbers.
