Number and operations. The student applies
mathematical process standards to develop and use strategies and methods for
positive rational number computations in order to solve problems with efficiency
and accuracy. The student is expected to:
(1) estimate to determine solutions to mathematical
and real-world problems involving addition, subtraction, multiplication, or
division;
(A) multiply with fluency a three-digit number
by a two-digit number using the standard algorithm;
(B) solve with proficiency for quotients of
up to a four-digit dividend by a two-digit divisor using strategies and the
standard algorithm;
(C) represent multiplication of decimals with
products to the hundredths using objects and pictorial models, including area
models;
(D) solve for products of decimals to the hundredths,
including situations involving money, using strategies based on place-value
understandings, properties of operations, and the relationship to the multiplication
of whole numbers;
(E) represent quotients of decimals to the hundredths,
up to four-digit dividends and two-digit whole number divisors, using objects
and pictorial models, including area models;
(F) solve for quotients of decimals to the hundredths,
up to four-digit dividends and two-digit whole number divisors, using strategies
and algorithms, including the standard algorithm;
(G) represent and solve addition and subtraction
of fractions with unequal denominators referring to the same whole using objects
and pictorial models and properties of operations;
(H) represent and solve multiplication of a
whole number and a fraction that refers to the same whole using objects and
pictorial models, including area models;
(I) add and subtract positive rational numbers
fluently; and
(J) divide whole numbers by unit fractions and
unit fractions by whole numbers.
