A question-and-answer book with a difference! Each of the 50 rounds covers one subject - from amphibians and Aztecs to weather and winter sports. The 20 questions in each round are carefully graded at three levels to build confidence and stretch knowledge-hungry minds, ranging from the really easy to the seriously challenging. Then comes the fun part - finding out the answers! Readers can jump to the quick answer section at the back of the book, or find out more by turning the page and hunting for the answer on two sumptuously illustrated and fact-packed pages.
