## Standards with the same topic and subject but for other grades

Apply and extend previous understandings of multiplication and division to divide fractions by fractions.

Fluently divide multi-digit numbers using the standard algorithm.

Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation.

Fluently divide multi-digit numbers using an algorithm.

Fluently add, subtract, multiply and divide multi-digit decimals using an algorithm for each operation.

Compute fluently with multi-digit numbers and find common factors and multiples.

Interpret and compute quotients of fractions, and solve word problems involving division of fractions by fractions, e.g., by using visual fraction models and equations to represent the problem.

Interpret and compute quotients of fractions and solve word problems involving division of fractions by fractions.

Perform operations with numbers expressed in scientific notation, including problems where both decimal and scientific notation are used. Use scientific notation and choose units of appropriate size for measurements of very large or very small quantities (e.g., use millimeters per year for seafloor spreading). Interpret scientific notation that has been generated by technology.
