"I like to read every time of the day," said Maria, a student at Creel Elementary School in Australia. Maria's headmaster, Mrs. White, wants each of her 850 students and their families to learn the love of reading this year. She wants reading at home to become an activity of choice in every family, even during holiday breaks. "I truly realize reading should be an important part of everyone's life, and nothing should stop it." said Mrs. White. "The aim we want most of all is to help children understand they can enjoy reading, as well as practice their skills," said Hannas, an education researcher. He suggested parents take their children to the library and allow them to pick out books that interest them. Each night, students take home two books to read with their parents or other family members. They have to return the books the next day with a signed note from their parents showing that the books were read, and have passing tests that check how well they understand the books. "We're trying to get parents into the habit of reading with their kids." said the headmaster. "Nothing is better than sitting on a sofa with your child and reading and laughing." Through books, Mrs. Smith, a parent, said she's able to give her two daughters more experiences than she could. "I think reading opens all the doors and creates imaginations in children," she said, "I think if you read well, you can succeed in anything in life."
