Grade Six Introduction to Angle Geometry

We began out introductory lesson with kinesthetic representations of obtuse, right, and acute angles.

Next, we participated in several prior knowledge activities; leading up to student- created definitions of each angle. Next, we searched the classroom for an example of each angle. Students worked against the clock to record one example of each while moving around the room.

Finally, we introduced the protractor as a measurement tool. We took to the playground to find examples of angles around the school property. What a fun Friday we had today!

acute angle - 70 degrees          obtuse angle - 140 degrees           right angle - 90 degrees 

obtuse angle - 140 degrees          right angle - 90 degrees           reflex angle - 270 degrees
