It's raining cats and dogs.
It is raining very hard
Break a leg
Good luck
Under the weather
feeling sick
Hit the hay
Go to bed
When pigs fly
Something that is never going to happen
On cloud nine
Very happy
Go the extra mile
To go above and beyond
Feeling blue
Feeling sad
Giving someone the cold shoulder
Ignoring someone
The early bird
Someone who wakes up early
My mom was Fed Up with me
She was tired of my behavior.
Put your best foot forward.
Try your best
A piece of Cake
When something is easy
To give a hand to someone
To help
My grandma was as sweet as pie
When someone is very friendly
Getting up on the wrong side of the bed
Being grumpy
When your mom tells you to cut it out
Stop what you are doing
If someone says you have a sweet tooth
Once in a blue moon
Something you don't do very often
What is an Idiom?
A phrase that has a different meaning
Pulling someones leg
Letting someone off the hook
Giving someone a second chance for what they did.
Killing two birds with one stone
Doing two things at once
Don't judge a book by its cover
Don't judge something by its appearance (what it looks like)
