Sir Cumference Gets Decima’s Point

Another great “addition” to the upper elementary math adventure series,  Sir Cumference Gets Decima’s Point by Cindy Neuschwander and illustrated by Wayne Geehan.

Follow Decima the ogre baker as she figures out how to divide her deserts for more and more hungry diners. When she thinks she finally has enough, disaster happens. How will she provide equal portions to everyone who wants them?

Hidden in the story of baking antics is a solid background in decimals. The endnote explains how it works in more straightforward mathematical terms.

Books like these that mix fact and fiction can be hard to categorize, but can play an important role in helping children who struggle with certain math concepts. Looking at the problem from a different perspective may be just the ticket to the understanding train.

Sir Cumference Gets Decima’s Point deserves a “place” in any math library. Might be a good choice for young readers who enjoy imaginative stories, as well. Add a copy to your reading list today!

Middle Grade Nonfiction Books for Pi Day

Did you know that next Saturday is Pi Day? Pi Day is celebrated on March 14 (3/14) as a fun way to honor the mathematical constant π, which is 3.14… This year Pi Day will have extra significance because on 3/14/15 at 9:26:53 a.m. and p.m. the date and time will represent the first 10 digits of π!

The traditional way to celebrate Pi Day is to bake a pie decorated with a π symbol and share it. This year, why not pull out some middle grade children’s books about pi and share those as well?

Sir Cumference and the Dragon of Pi (A Math Adventure) by Cindy Neuschwander and illustrated by Wayne Geehan

Not exactly nonfiction, but a classic for Pi Day, this book is the second of a very popular series that turns common math concepts into memorable stories. Meet the regulars in King Arthur’s court, such as Sir Cumference, his wife Lady Di of Ameter, their son Radius, and the carpenter, Geo of Metry. When Sir Cumference turns into a dragon, can his family and friends use math to save him? Although it looks a bit like a picture book, the concepts are actually for middle grades.

Why Pi? (Big Questions) by Johnny Ball.

Why Pi? is not just about pi, but is a general history of all things math. It covers how humans have used numbers and measured things from the past all the way to the present. Pages are bright colors, some contrasted with black like the cover. This is a follow-up book to the award-winning title, Go Figure, by the same author, which contains information about why all the world’s phone numbers appear in pi.
