Idioms are special phrases that say one thing but mean something different. People use idioms to make their talking more fun and easy to remember. For example, if someone says, “It’s raining cats and dogs,” they don’t mean animals are falling from the sky. They just mean it’s raining very hard. Idioms are like puzzles in a sentence. When you figure them out, they help you understand the message better.
Children in the USA hear idioms in school, at home, and even on TV. Learning these phrases can help kids talk better, read with more understanding, and enjoy stories more.

Reading Passage
It was Valentine’s Day at Brookside Elementary. Ms. Carter’s class was having a party with games and treats. Before the fun started, she said, “Put your thinking caps on we’re going to play a word riddle game.”
While the kids were solving clues, Jake spilled the beans about the surprise cupcakes. “Jake!” said Maya. “You let the cat out of the bag!”
Then it began to rain outside hard. “It’s raining cats and dogs,” Ms. Carter said as they looked out the window.
Liam told a joke to break the ice with the new student, Emma. She laughed, and he felt butterflies in his stomach. They played musical chairs, and Emma won. “She really went the extra mile to win that game,” Jake said.
Just before snacks, Mia whispered, “Keep an eye on those cupcakes. I think someone’s eyeing them.” Noah pretended he knew nothing. “Cat got your tongue?” Mia asked.
Ms. Carter smiled. “Let’s not cry over spilled milk if someone drops a cookie,” she said. Then the cupcakes arrived, and everyone was on cloud nine.
