Interactive Middle school math activity about geometry concepts. Combines audio, kinesthetic, and visual learning styles.

1. Tri-kinetic Challenge!!! Linda Weatherford Middle School Math Methods Prof. Irving Lubliner October 4th, 2011

2. A Bit of Angle-ing First! Right Angle (Exactly ninety degrees) Acute Angle (Less than ninety degrees) Obtuse Angle (More than ninety degrees)

3. Triangle Time Right Triangle (Contains a right angle) Acute Triangle (All angles are LESS THAN 90o) Obtuse Triangle (Contains an angle GREATER THAN 90o)

4. Where are the Equivalencies? Equilateral Triangle (All sides and all angles are equal) Isosceles Triangle (Two equal sides, and two equal angles) Scalene Triangle (NO equal sides, NO Equal angles)

5. Time to get Kinetic! Rules: Everybody participates Each shaper must be blindfolded while in motion (NO peeking!) Everybody is respectful and safe to others

8. Further Thoughts… What did you learn from our activity? Can triangles have more than one description? Why do equilateral triangles always have sixty degree angles? Can an Isosceles triangle have an obtuse angle?
