Reading Passage
It was Library Week at Lincoln Elementary, and the students were more excited than ever. On Monday, Ms. Carter told the class they would start a book club and read a mystery novel together. Jake, who’s a total bookworm, could hardly wait. When they got their books, he cracked a book right away and started reading.
At recess, Lily said she was trying to take a leaf out of Jake’s book by reading more often. Emma, who had trouble with chapter books, said they used to be a closed book to her. But now she had a reading buddy to help her.
During reading time, Sam whispered, “This story is a real page-turner!” They all nodded. Later that week, the principal came to class and said, “You’re all in my good books for reading so much.” Everyone cheered.
On Friday, they had a contest to write a book report. Jake read his aloud. “Don’t judge a book by its cover,” he said. “This story is full of surprises!” Ms. Carter smiled and said, “That was great now turn the page and get ready for our next adventure.”
