Multi-Digit and Fraction Computation

Objective

Divide multi-digit whole numbers using the standard algorithm.

Common Core Standards

Core Standards

?

• 6.NS.B.2 — Fluently divide multi-digit numbers using the standard algorithm.

?

• 4.NBT.B.6

• 5.NBT.B.6

Criteria for Success

?

1. Divide multi-digit whole numbers using partial quotients.
2. Understand the connection between the standard algorithm for division and partial quotients.
3. Apply the standard algorithm for division to solve problems.

Tips for Teachers

?

• In fifth grade, students found whole number quotients with up to 2 digit divisors and 4 digit dividends using various strategies. In sixth grade, dividing multi-digit whole numbers is a fluency expectation. This lesson reviews partial quotient strategies from fifth grade and students are guided toward understanding the standard algorithm as an efficient way to compute. Ensure students have opportunities to build towards fluency throughout the unit and the year. See our Guide to Procedural Skill and Fluency for additional information and strategies.
• The following tools or materials are useful for this lesson: large graph or grid paper for computations, calculators to check answers.

Remote Learning Guidance

If you need to adapt or shorten this lesson for remote learning, we suggest prioritizing Anchor Problem 2 or 3 (benefit from worked examples). If students have a strong grasp on using the standard algorithm to divide whole numbers, then this Anchor Problem can either be skipped or done independently.
