Customizable Inscribed Angle Geometry Manipulative
Description
This Is A 6" Diameter Fully Customizable Geometry Manipulative That Can Be Useful In The Teaching And Learning About The Properties Of Angles, Inscribed Angles, Central Angles, Arc Lengths, And Arc Measures. Use With A Rubber Band Or Two To Discover The Relationship Between Inscribed And Central Angles . Holes For Small Nails Are Equally Spaced Around The Circumference Along With One In The Center. An Stl File Of A 6" Disk That Printed Well Is Also Included If You Don'T Want To Mess With The Customizer. If Planning On Using This To Complement Lessons On The Subject, Print A Classroom Set So Each Student Can Explore, Or At Least Print Enough So That Each Table Group Can Share One. Additional Materials Needed: Rubber Bands Small Nails ( I Used Some 5/8" Nails I Had In My Workshop With 0.8Mm Holes) To Tap Into Holes Hammer If You Like This, Check Out My Other Objects, Including The Non-Customizable Version Of This Manipulative At: Http://Www.Thingiverse.Com/Thing:2179477. Also, If You Want A Modification To This Design, Let Me Know In The Comments And I'Ll See What I Can Do. ***Updated 3/19/17*** - A New Version Was Modeled In Inventor (See The Version 4 Stl File, Not Added To Customizer File Yet) That Has 24 Central Angles (15 Degrees Each) Around The Whole Circle, Along With 12 Inscribed Angles Radiating 180 Degrees From A Single Point On The Circumference (7.5 Degrees Each). The Intent Is To Better Show The Relationship Between Central Angles And Inscribed Angles.
