  If you had to classify angles how would you do it?  How many groups would there be?  What would you name each group? What do you think?

  LG: Classify a given set of angles according to their measure  Kid Friendly: Name types of angles depending on how many degrees they are  What I think I know: Learning Goals

  Angles can be broken up into different groups  These groups are based on how many degrees, or in other words how much they turn  As an angle increases, the name changes  Sort of like how the moon changes and has different names for its phases! Classifying

 Type of AngleDescription Acute anglean angle that is less than 90° Right anglean angle that is 90° exactly Obtuse anglean angle that is greater than 90° but less than 180° Straight anglean angle that is 180° exactly Reflex anglean angle that is greater than 180° Full Rotationan angle that is exactly 360° Different types of Angles

  Draw the following angles:  0 degrees, 180 degrees, 360degrees  How are these three angles different? What makes this obvious?  Draw two different reflex angles  Draw a 90degree angle. What other angle could be shown using the same diagram?  Draw (approximately) a 20degree angle. What other angle could be shown using the same diagram?  Find the missing measurements: Mental Math Warm Up

  Find a way to creatively explain angles and specific classifications of angles  For example:  an educreations video (only a few iPads to use)  a comic  a song  a piece of artwork  other unique ideas  You must include ___ of the following words:  Angle, arc, arm, vertex, line segment, base line, right angle, acute, obtuse, straight angle, reflex Creative Math
