Reading Passage
It was Valentine’s Day at Riverdale Elementary. The class was decorating cards and stringing red hearts on the walls. Mrs. Carter asked the students to keep it under their hat about the surprise for Principal Jones. Everyone nodded and zipped their lips.
Later that day, something strange happened. Right before the big Valentine’s party, a hush fell over the classroom. The cupcakes were missing! Nobody said a peep. Mrs. Carter looked around and asked, “Cat got your tongue?” The students just looked at each other.
Sam tried to speak, but his words were stuck in his throat. Lucy was tongue-tied, holding a note behind her back. “Speak in a whisper,” said Mrs. Carter. Lucy handed over the note. It read: “Check the art room.”
They all tiptoed over quietly, quiet as mice. There they found the cupcakes, safe and sound. Everyone laughed and gave Lucy a big smile.
The class promised to seal their lips about what really happened. Mum’s the word, they all agreed.
