In this entertaining math adventure, Sir Cumference’s son, Radius, enters upon a quest. Quests were the thing to do for aspiring knights in the ancient land of Angleland (apparently now known as England on current maps). So Radius goes to rescue King Lell, and takes with him a medallion, very much like a protractor. He uses it to determine angles which help him to follow the clues to find the missing king. When he is successful, angles are named after similar places in his adventure, such as the Mountains of Obtuse. Plenty of math terms find themselves in the story, which make it all the more entertaining. Such a great way to introduce geometry to younger children!
