    Have you met Sir Cumference? He’s such a wonderful person, along with his wife, Lady Di, and son, Radius. His friends can’t be beat either - King Arthur, Geo of Metry, Sym, Sir D’Grees, King Lell, Per, Countess Areana, Vertex, Sir Tangent, Sir Lionel Segment and others.

    Living in Camelot under King Arthur, Sir Cumference and his buddies must work through many complications that require mathematical and logical thinking. During visits to such places as the Mountains of Obtuse, Angleland and the Isle of Immeter, people must be rescued, clues must be found and problems must be solved!

    The stories are full of action and suspense that have kept my children enthralled time and time again. The author, Cindy Neuschwander, is an absolute genius in the creativity of these books! It’s beyond me how the books not only have a great plot, but teach math concepts within the storyline – and don’t lose any qualities of living literature in the process!

    Depending on the book(s) you read, the following concepts are covered:

    * Circumference
    * Diameter
    * Radius
    * Pi
    * Angles
    * Lines
    * Measurement
    * Perimeter
    * Area
    * 3-D shapes
    * Counting by 10’s, 100’s, 1,000’s

    Any child 1st grade and above will enjoy listening to the stories, but older children (4th grade and higher) will most likely grasp the math concepts best. I used to check the books out from the library until I almost wore my card out rechecking them! Now, I’m the proud owner of each and every one. (A CM homeschool can never have enough living literature on the bookshelves, can it?)
