Math Picture Books to Love: Sir Cumference and the Great Knight of Angleland

Sir Cumference and the Great Knight of Angleland by Cindy Neuschwander
  • Target Skill(s): Identify Acute, Right, Obtuse, and Straight Angles; Measure Angles, Identify Parallel Lines
  • Book Synopsis: Radius, son of Sir Cumference and Lady Di of Ameter, wanted to be a knight. He practiced every day until his teacher said he was ready for his first quest. Radius then set out with a medallion given to him by his parents. While on his quest, Radius stumbled upon an old castle with a note attached to the door. On the note was a riddle with directions to reach a kidnapped King. With his horse, Radius used his medallion (a protractor) to find the correct angles and the right paths to take to find the King. Radius saved the King and received his knighthood. 
  • Math Involved: This books reinforces how to use a protractor to measure angles and emphasizes the use of geometric vocabulary to identify angles (right, acute, obtuse, and straight) and types of lines.
  • Questions to Ponder:
    • What are the four types of angles? Describe each.
    • What are parallel lines? 
    • What tool do we use to measure angles?
    • How do you measure angles?
    • What are degrees?
  • Activity Ideas: 
    • Create a medallion protractor for each student (some of the books include this). Have the students use the medallions to measure various angles. 
    • Have students find and identify examples of angles around the classroom. 
    • Provide students with angles to measure. Have students sort the angles into groups of knightly right, big, straight, and slight angles (like Radius's angles in the story).
