Bill gets a new bike for his birthday. He loves to ride it around, but soon finds out how many wheels he needs! The Tiddlers series contains stories with a word count of fewer than 50 words for children who are just starting to read. A word list at the start of the book allows you to check the child"s ability to decode and understand each word before reading, providing a fully supported first reading experience. And a puzzle at the end of the story encourages rereading for pleasure.
