Recognize volume as an attribute of solid figures and understand concepts of volume measurement.

Convert among different-sized standard measurement units within a given measurement system (e.g., convert 5 cm to 0.05 m), and use these conversions in solving multi-step, real world problems.

Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions.¹

Solve real world problems involving multiplication of fractions and mixed numbers, e.g., by using visual fraction models or equations to represent the problem.

Interpret multiplication as scaling (resizing), by:

Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction.

Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.

Find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.

Read, write, and compare decimals to thousandths.

Use place value understanding to round decimals to any place.
