Math Mentor Text: Sir Cumference and the Great Knight of Angleland

Happy Sunday! Did you miss that hour of sleep this morning? I didn't, because I overslept anyway! :-P
I want to share a fun math book with you that we used this week: Sir Cumference and the Great Knight of Angleland! The author, Cindy Neuschwander, has a bunch of these math adventure books. This one is perfect for geometry! Amanda actually shared about it in August- you can read her post here... and Bethany shared about it in this post!
In this book, Radius is on a quest to become a knight. He has had training from Sir D'Grees where he learned to make a "knightly right angle," and doubled it to make a straight angle. He has a circular medallion (protractor) that he uses on his quest to rescue the missing King of Lell (and his two twin dragons: the Pair of Lells- get it??) ...his quest involves following the directions of acute, right, and obtuse angles.

I had already taught my students how to identify angles using the activity from my geometry pack.
As I read, we practiced making the angles on geoboards and measuring them with our own protractors! Anytime you pull out a fun manipulative like this one, you have to let them "play" for a few minutes and get it out of their system. ;o) 
But then we got right to work! They made different angles with the rubberbands...
...and practiced using our protractors to measure the angles!
Do you have any great math books you use in your classroom? Link them up with Collaboration Cuties!

  2. I love the idea of using the geoboard to create angles that you can measure with your protractor. I wish I would have known about this back when I still taught math because it is such a great idea. Thanks for sharing!

  7. First of all your fresh site looks great! I can't wait to get mine spruced up. Secondly, thanks for the great ideas. I am starting my geo strand unit (after about ten thousand snow days) and this will be great fun!!! Thanks again and keep the great ideas rolling!!!
