Back in the days of Camelot, people knew geometry, but they learned it in adventures instead of textbooks. Per of Ameter played a game created by the Countess Areana in which they figured the outside edges and inner pieces of shapes made with the same size squares. Their skill at this game allowed them to solve several mysteries on the Isle of Immeter through a few escapes, as the island was protected by a sea dragon. Finally Per solved all the puzzles, and the sea dragon delivered a locked from the Countess Areana giving Per ownership of the island. When the two children returned from their adventure, Sir Cumference named the measurement of the outside edge of any flat, straight sided shape perimeter, after Per, who now was the Lady of Immeter. The inside of the shapes was called Area, after the Countess Areana who designed all the puzzles they solved. And so, as you will know if you have read this book, this is a cute, abbreviated account of the true way geometry really evolved.
A handy chart on the last page explains in mathematical terms the formulas described in the book.

Great math aide
This book, and series of books, is a great aide in teaching math concepts. They personify the concepts, give kids visuals to associate with so they can remember what each concept/term means. The stories are cute, not contrived, and do a play on words quite a bit.

Cir Cumference Series Awesome find Great Fun Math resource
The entire Sir Cumference Series are a wonderful way to entertain children while teaching math concepts. They don't even realize they are learning, they enjoy the stories. Each story connects math applications in ways children understand and can apply. What a wonderful gift. :)

Excellent for tying literature to mathematics.
Excellent for tying literature to mathematics. Children love these books and so do I!

Even in Middle School they still like to be read to
This whole series of books is wonderful. The story line for a middle school level is somewhat elementary, but the students still LOVE them. They remember the terms and even bring them up during lessons. I think even at the middle school levels, the kids really like being read to and these books ,as silly as they seem when read at that level, help solidify these key geometry concepts in a fun kind of way. They take about 10-15 minutes to read out loud. Highly recommend!
