(4) Number and operations. The student applies mathematical process standards to develop and use strategies and methods for whole number computations and decimal sums and differences in order to solve problems with efficiency and accuracy. The student is expected to:

• (A) add and subtract whole numbers and decimals to the hundredths place using the standard algorithm;

• (B) determine products of a number and 10 or 100 using properties of operations and place value understandings;

• (C) represent the product of 2 two-digit numbers using arrays, area models, or equations, including perfect squares through 15 by 15;

• (D) use strategies and algorithms, including the standard algorithm, to multiply up to a four-digit number by a one-digit number and to multiply a two-digit number by a two-digit number. Strategies may include mental math, partial products, and the commutative, associative, and distributive properties;

• (E) represent the quotient of up to a four-digit whole number divided by a one-digit whole number using arrays, area models, or equations;

• (F) use strategies and algorithms, including the standard algorithm, to divide up to a four-digit dividend by a one-digit divisor;

• (G) round to the nearest 10, 100, or 1,000 or use compatible numbers to estimate solutions involving whole numbers; and

• (H) solve with fluency one- and two-step problems involving multiplication and division, including interpreting remainders.
