OA.2 - Division Review

Let's review our 4 ways to divide, and then complete practice problems!

What is division?

• Division is when we take the TOTAL amount and BREAK IT APART into smaller groups

• When something is evenly distributed, or broken part, you are dividing!

• You can divide up money, food, shells, baseball cards, etc.

Equal Groups

• Look at the divisor to know how many groups to make

• Look at the dividend to know how much we need to divide

• Divide the dividend by placing that number of dots into the circle

• Count how many are in 1 circle to find the quotient

Arrays

• Use the dividend for the number of items

• Use the divisor to determine how many go in each row

• Count the rows to determine the quotient

Repeated Subtraction

• Subtract the divisor from the dividend

• Subtract the divisor from that answer

• Continue subtracting until you reach 0

• Count how many times you subtracted to find the quotient

Using Multiplication

• Look at the dividend and divisor

• Think, "what times my divisor will equal my dividend?"

• Consider your fact families to find the missing number
