Week: 5
Lesson 8 – Divide Multi-Digit Numbers
Standard: 6.NS.B.2
Fluently divide multi-digit
numbers using the standard
algorithm.
Essential Question
Can I divide multiple digit numbers by
using the standard division algorithm?
I can divide multi-digit numbers
using the standard algorithm.
I can use repeated
multiplication and subtraction
to divide multi-digit numbers.
Big Idea
Apply previous skills of concrete models
and various strategies in previous grades
over division.
Vocabulary
Quotient, partitive, quotative,
inverse, bar model expression,
estimate, partial quotient,
algorithm, division, compatible
numbers, divisor, dividend
Grade: Sixth
Learning Targets
Fluently divide multi-digit numbers
using standard algorithm. (4 digit by 2
digit)
Use context of question to properly
align the problem.
Interpret what the quotient means or
stands for
Recognize the unknown shows the
type of divison needed. (parititive or
quotative) (p.78 teachers’ edition)
Ready Resources
Journal Task
1. How in your words are
multiplication and division
considered to be inverse
operations?
2. Describe what actually is done
during the performance of the
division algorithm. (multiply and
subtract)

Resource
In sixth grade the foundation of division has been laid in previous grades
using manipulatives. Here is a video that you could share with the class that
models division of multi-digit numbers with students that are having difficulty
with the concept of division.

Strategies:
Review fair sharing or repeated
subtraction
Use inverse operations to help with the
skill.
Use compatible numbers and
estimation to help with mastery
