Divide with 1 and 0 MAFS.3.OA.3.7

Lesson Opening Write an equation that represents the following situation. Use the letter c to represent the unknown. Sharon has 6 cookies and 3 cookie jars. She wants to put the same number of cookies in each jar. How many cookies will she put in each jar?

There are 3 cookies and 1 jar. How many cookies are in the jar? Dividing with 1 There are 3 cookies and 1 jar. How many cookies are in the jar?

There are 3 cookies and 1 jar. How many cookies are in the jar? Dividing with 1 There are 3 cookies and 1 jar. How many cookies are in the jar?

Dividing with 1 There are 3 cookies and 1 jar. How many cookies are in the jar? 3 ÷ 1 = 3 Number of cookies Number of jars Number of cookies in each jar

Dividing with 1 There are 3 cookies and 1 jar. How many cookies are in the jar? RULE: Any number divided by 1 equals that number.

There are 3 cookies and 3 jars. How many cookies are in each jar? Dividing with 1 There are 3 cookies and 3 jars. How many cookies are in each jar?

There are 3 cookies and 3 jars. How many cookies are in each jar? Dividing with 1 There are 3 cookies and 3 jars. How many cookies are in each jar?

Dividing with 1 There are 3 cookies and 3 jars. How many cookies are in each jar? 3 ÷ 3 = 1 Number of cookies Number of jars Number of cookies in each jar

Dividing with 1 There are 3 cookies and 3 jars. How many cookies are in each jar? RULE: Any number divided by itself equals 1.

Dividing with 0 If there are 0 cookies and 3 jars, how many cookies will be in each jar?

Dividing with 0 If there are 0 cookies and 3 jars, how many cookies will be in each jar?

Number of cookies in each jar Dividing with 0 If there are 0 cookies and 3 jars, how many cookies will be in each jar? 0 ÷ 3 = 0 Number of cookies Number of jars Number of cookies in each jar

Zero divided by any number (except zero) equals 0. Dividing with 0 If there are 0 cookies and 3 jars, how many cookies will be in each jar? RULE: Zero divided by any number (except zero) equals 0.

Dividing with 0 If there are 3 cookies and 0 jars, how many cookies will be in each jar?

Dividing with 0 If there are 3 cookies and 0 jars, how many cookies will be in each jar?

Number of cookies in each jar Dividing with 0 If there are 3 cookies and 0 jars, how many cookies will be in each jar? 3 ÷ 0 = Number of cookies Number of jars Number of cookies in each jar

Dividing by zero is NOT possible. Dividing with 0 If there are 3 cookies and 0 jars, how many cookies will be in each jar? You cannot separate the cookies equally into jars because there are NO jars. Dividing by zero is NOT possible. 3 ÷ 0 = Number of cookies Number of jars Number of cookies in each jar

Dividing by zero is NOT possible. Dividing with 0 RULE: You CANNOT divide a number by 0. Think of the related multiplication fact: _____ x 0 = 4. Nothing times 0 will give you 4. If there are 3 cookies and 0 jars, how many cookies will be in each jar? You cannot separate the cookies equally into jars because there are NO jars. Dividing by zero is NOT possible. 3 ÷ 0 = Number of cookies Number of jars Number of cookies in each jar

What are the rules for dividing with 1 and 0?

Exit Ticket 5 ÷ 1 2 ÷ 2 0 ÷ 3 What is the quotient? Choose one of the expressions above and write the related facts for it.
