COMMON CORE STANDARDS FOR
MULTIPLICATION
Perform operations with multi-digit whole numbers and with decimals to hundredths.
CCSS.MATH.CONTENT.5.NBT.B.5
Fluently multiply multi-digit whole numbers using the standard algorithm.
CCSS.MATH.CONTENT.5.NF.B.4
Apply and extend previous understandings of multiplication to multiply a fraction or
whole number by a fraction
CCSS.MATH.CONTENT.5.NF.B.6
Solve real world problems involving multiplication of fractions and mixed numbers,
e.g., by using visual fraction models or equations to represent the problem.
MULTIPLICATION FACT FLUENCY
It is imperative that your child knows their multiplication
facts Fluently!.
Students should be able to solve 60 multiplication facts
in less than 2 minutes.
BAR MODEL FOR MULTIPLICATION
This is a conceptual model of a multiplication problem.
If the problem is
The model looks like
23
23 x 45
45
AREA METHOD FOR MULTIPLICATION
TRADITIONAL MODEL OF MULTIPLICATION
COMMON CORE STANDARDS FOR DIVISION
5th grade CCSS.MATH.CONTENT.5.NBT.B.6
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.
6th Grade CCSS
Compute fluently with multi-digit numbers and find common factors and multiples.
CCSS.MATH.CONTENT.6.NS.B.2
Fluently divide multi-digit numbers using the standard algorithm.
CCSS.MATH.CONTENT.6.NS.B.3
Fluently add, subtract, multiply, and divide multi-digit decimals using the standard
algorithm for each operation
