Advanced Multiplication

Introduction to multi-digit multiplication

Two digits times one digit

Set 1:     multiplication 1     multiplication 2     multiplication 3     multiplication 4     multiplication 5

Set 2:     multiplication 6     multiplication 7     multiplication 8     multiplication 9     multiplication 10

Division – Introduction to Remainders  [CCSS Standard.4.NBT.B.6]

Simple division w/ whole number quotients up to 12, divisors up to 12, and remainders

Example:  50 ÷ 8 =  

Division Remainders 1    Division Remainders 2    Division Remainders 3    Division Remainders 4    Division Remainders 5

Beginning Long Division

ILong Divisionntroduction to long division  [CCSS Standard.4.NBT.B.6]

Step 1:  Simplest examples – one digit divisor which fits into the first digit of the dividend.  These are the easiest samples to learn the steps to long division.  

 With grid and clues…

Set 1:     long division 1     long division 2     long division 3     long division 4     long division 5

Set 2:     long division 6     long division 7     long division 8     long division 9     long division 10

With grid but no clues…

Set 1:     long division 1     long division 2     long division 3     long division 4     long division 5

Set 2:     long division 6     long division 7    long division 8      long division 9     long division 10

No grid, no clues.  You’re on your own…

Set 1:     long division 1     long division 2     long division 3     long division 4     long division 5

Set 2:     long division 6     long division 7     long division 8     long division 9     long division 10

Step 2:  Now a twist – one digit divisor which does not fit into the first digit of the dividend.    

With grid and clues:  Long Division 1     Long Division 2     Long Division 3     Long Division 4     Long Division 5

With grid but no clues:   Long Division 1     Long Division 2     Long Division 3     Long Division 4     Long Division 5

No grid, no clues:      Long Division 1     Long Division 2     Long Division 3     Long Division 4     Long Division 5

Step 3:  Now with remainders.    

Remainders with grid:

 w Remainders 1     w Remainders 2     w Remainders 3     w Remainders 4     w Remainders 5

w Remainders 6      w Remainders 7     w Remainders 8     w Remainders 9     w Remainders 10

Remainders without grid:

 w Remainders 1    w Remainders 2      w Remainders 3    w Remainders 4    w Remainders 5
