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

Beginning Long Division

Introduction 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
