Multiply multi-digit whole numbers using the standard algorithm and verify each product with a second method such as partial products or area model.

Divide whole numbers with up to four-digit dividends and two-digit divisors, and interpret remainders in context.

Evaluate numerical expressions containing parentheses, brackets, and braces by applying order of operations in the correct sequence.

Translate simple verbal statements into expressions with a letter standing for an unknown, then solve for that unknown.

Multiply and divide decimals by powers of ten, and state the direction and number of place shifts for each operation.

Multiply decimals to the hundredths using a model and the standard procedure, then compare the two results.

Estimate decimal sums, differences, and products before computing, and judge whether an answer is reasonable.

Add and subtract fractions with unlike denominators by finding common denominators, and simplify results.

Solve fraction word problems involving the same whole, using visual fraction models to justify each step.

Interpret a fraction as division of the numerator by the denominator, and convert between improper fractions and mixed numbers.

Multiply a fraction by a whole number and by another fraction, using an area model to show the product.

Divide a unit fraction by a whole number and a whole number by a unit fraction, and explain each quotient using a story context.
