Unit 2 Arithmetic Operations Including
Division by a Fraction Grade 6 Math 

Unit Length and Description: 25 days In Unit 2, students
extend their knowledge of dividing whole numbers by unit fractions using
visual models and equations to divide whole numbers by fractions and
fractions by fractions to solve word problems. During this unit, students
develop procedural fluency. Students become fluent in the use of the standard
division algorithm. Students also
become fluent in the use of the standard algorithm as they add, subtract,
multiply, and divide multidigit decimals. The focus of instruction is on
operations and number sense. The use of estimation strategies supports
student understanding of decimal operations. Students extend
their understanding of greatest common factor and least common multiple that
began in Unit 1. Students find the greatest common factor of two whole
numbers less than or equal to 100, they understand that the greatest common
factor of two prime numbers will be 1, they use the greatest common factor
and the distributive property to find the sum of two whole numbers, and
students use the least common multiple of two whole numbers less than or
equal to twelve. 

Standards:


Enduring Understandings: ·
The
relationship of the location of the digits and the value of the digits is
part of understanding multidigit operations. ·
Operations on decimals and whole numbers are
based upon place value relationships. ·
When we divide one number by another, we may
get a quotient that is bigger than the original number, smaller than the
original number, or equal to the original number. ·
Least common multiple and greatest common factor are helpful
when solving realworld problems. ·
Multiplication
and division are inverse operations. 
Essential Questions: ·
What role does place value play in multidigit
operations? ·
How can the distributive
property help me with computation? ·
When I divide one number by
another number, do I always get a quotient smaller than my original number? ·
Which strategies are helpful
when performing operations on multidigit decimals? ·
What kind of models can I use
to show solutions to word problems involving fractions? ·
How can I check a division
problem?
