Free Write about Divide and Zero

DIVIDE
A mathematic concept
The opposite of multiply
Sharing among people
ie, have a pie or cake at birthday party, and you have ten guests, how much can each person get
ie, when we go out having dinner with friends, and we want to split the cost equally, use division as well


ZERO
It’s nothing, like empty
If the price of something is zero dollar, it means it’s free!
0 --> it’s a circle

Zero is in the middle of the number line
It’s the division between positive and negative numbers
It’s neither positive nor negative
It’s by itself

Anything add or subtract zero doesn’t change anything, stay the same
Zero times any number is zero
Zero divides any number is zero
0! = 1

0 degree Celsius is really cold
Get 0 on the test is really sad : (
