Ten terrible dinosaurs standing in a line, soon began to mess about until there were . . . nine.
Ten Terrible Dinosaurs, a lively counting book first published in 1997 and now reissued as a board book, is based on the characters from Dinosaur Roar!, a picture book that is now recognised as a modern classic. The rhyming text encourages children to join in, helping them to learn their numbers as they count down from ten to one, ending with a wonderful loud ROAR!
