COMMON CORE STANDARDS FOR MULTIPLICATIONPerform 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 23 x 45

The model looks like

2345

AREA METHOD FOR MULTIPLICATION

TRADITIONAL MODEL OF MULTIPLICATION

COMMON CORE STANDARDS FOR DIVISION5th 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
