Sir Cumference and the Roundabout Battle

  • 1695

By: Cindy Neuschwander / Illustrated by: Wayne Geehan

The castle is precisely under attack. Can Rounds 2 figure out a way to help?

Despite having to learn how to make accurate counts of the castle's stores of food, supplies, and weaponry, Rounds 2 decides to investigate a group of strangers camped nearby. When he reports back that an enemy is lying in wait, everyone moves quickly to defend the castle.

But wait! Will Rounds 2 be able to figure out how many bows and arrows they have to create an appropriate battle plan?

Using rounding techniques to figure out the totals more quickly, Rounds 2 is just in time to help stave off a potentially disastrous attack.

Wayne Geehan's whimsical illustrations are full of action and adventure, while accurately diagramming rounding techniques.

School Library Journal

This latest series installment uses stories involving a knight named Sir Cumference as jumping-off points to explore mathematical concepts tackles rounding. Edmund Rounds and his son, Rounds 2, are responsible for keeping an inventory of items at Sir Cumference’s castle. When Rounds 2 hands over his latest counts for inspection, Edmund notices that the number of bread loaves and butter pots has not been totaled. Rounds 2 admits that adding is the difficult part. As they total the items together, he finds that it is much easier to calculate numbers in groups of 10 (10, 20, 30, etc.). His father tells him that for some items, such as the number of bees in the hives, it’s acceptable to come up with an approximate number. To thank his father for his assistance, Rounds 2 sets off to count the bedding of some travelers passing by but discovers that the men are enemies intent on attacking the castle. As Sir Cumference prepares for battle, he asks Rounds 2 to retrieve the bow and arrow counts. While these items have been counted, they have not yet been totaled, and Rounds 2 is left to complete the calculations himself. By rounding up or down to the nearest 10, Rounds quickly completes the task in what soon becomes known around the castle as the Rounds 2 Method. VERDICT Complete with the illustration style and subtle puns expected of the series, this title will be enjoyed by fans of the previous books.


A young boy, Rounds 2, learns to round off numbers as he must quickly determine how many bows and arrows there are in the midst of battle. A new addition to the Sir Cumference series, the story is entertaining, and the math is delivered with a practical application. Because of the dearth of information on this subject, this may prove highly useful. The acrylic-paint-on-canvas illustrations are rich with color. The people are somewhat stiff, but their eyes are full of personality. An old word for a beehive, skep, is used, which may send some readers to the dictionary.
