### Long Division

Long Division is a step by step method for dividing the multi-digit numbers. It involves 4 basic steps: Divide, Multiply, Subtract, Bring Down, and then repeating the process.

Students often have difficulty in following the long division steps. A funny Acronym to remember these steps is:
Dirty Monkeys Smell Bad!

 Long Division Steps Poster

Here is my Long Division pack to learn and practice long division with easy to follow grid assisted worksheets.

This pack includes worksheets for 2, 3, and 4 digit dividends with single digit divisors. A total of 30 worksheets covering different types of problems with remainders and no remainders kind.

Acronym poster and answer key is included.

### Divisibility Rules

Divisible: When one number can be divided by another number without leaving a remainder.
For example, 6 is divisible by 3.

Divisibility rules of whole numbers help us to quickly determine if a number can be divided by 2, 3, 4, 5, 9, and 10 without doing a long division. These rules have a wide range of applications in mathematics like finding factors, determining prime versus composite numbers and simplifying fractions etc.

Knowing the divisibility rules will prepare students to work with larger numbers. You may introduce the concept in grade 4 and as a refresher for 5th graders.

Use these worksheets and a ready reference poster to have students familiarize and practice the divisibility rules. Included are 11 worksheets and 2 posters (both in Colored and Black & White versions) for dividing by 2, 3, 4, 5, 6, 9, and 10.

You may also print the poster as 2 copies per page and have students stick in their notebooks for quick reference.

You can buy this Divisibility Rules pack from HERE.

### Division Facts

Division is one of the four basic operations of arithmetic, the other being addition, subtraction, and multiplication. Once kids are fluent in multiplication facts, teaching division becomes easy. My today’s post is on introducing the concept of division to the young learners.

#### Introducing Division

Division is a sharing operation, where objects are shared equally into a number of groups.

Hands on Activity: Give 9 pennies or counters and 3 bowls to each child and tell them to put equal pennies/counters in each bowl.

If the result is as shown in picture, tell them - This is what the division is.

#### Multiplication and Division relationship (Multiplication and Division Fact Family)

Multiplication and Division has inverse relationship just like addition and subtraction.

Example:
Multiplication Equation:  4 x 5 = 20
The two division equations will be:
20 ÷ 5 = 4
20 ÷ 4 = 5

Similarly, we can derive multiplication equations from division equation.
35 ÷ 5 = 7

The two multiplication equations will be:
7 x 5 = 35
5 x 7 = 35

Understanding the multiplication and division relationship is very important in solving the division problems.

#### Division Vocabulary

Dividend: A number to be divided by another number.
Divisor: A number by which another number is divided.
Quotient: The result of division.

This division vocabulary poster is also included in my division packet.

You can use this division booklet to teach division facts up to 12 without a remainder. Worksheets covering the above concepts are included in this packet.

This division packet can be purchased from HERE
