Sir Cumference and the roundabout battle

Gr 2-5-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.-Meaghan Darling, Long Hill Township Public Library, Gillette, NJ © Copyright 2015.

Rounds 2, the castle steward's son, uses rounding to calculate the number of bows and arrows Sir Cumference and his archers have for defense. The arrow count isn't high enough to defeat the castle's attackers, so Rounds 2 comes up with another plan. Mathematical thinking is modeled well, and the series' trademarks--amusingly groan-worthy puns and acrylic illustrations set in the Middle Ages--make their usual appearance. (c) Copyright 2016.

"Another great harvest day! But wait--who's that?" asked Edmund Rounds, the castle steward. He pointed to a few small tents just visible among the trees.             "It's probably travelers bedding down for the night," answered Sir Cumference.             Just then the steward's son bounded up the stairway.             "Ah, Rounds 2, keeping track of everything in the castle?" asked Sir Cumference with a smile.             The boy nodded. Everyone called him Rounds 2, since he and his father were both named Edmund.             "Papa, I've finished the counts you asked for," he said, handing his father two scrolls. As the castle's next steward, Rounds 2 was his father's assistant.             "Wonderful!" exclaimed Steward Rounds. "Let's look these over during supper."
