HW/Geometry

Tuesday, 1/8 HW

Math

  • pg. 100,101,102 f/b (it's about 20 very easy problems and 5 thinkers!)
  • HOTS POW
ELA
  • Spelling Contract
  • Read 15 minutes on your lexile level


Yesterday we begin our geometry exploration!  Today we explored angles and polygons with marshmallows and toothpicks! 


http://www.mathsisfun.com/definitions/right-angle.html  on the bottom of the definition there is a moveable angle-maker/shower :)  The kids loved using it today! 

Review our vocabulary words every night.  We add words to our Geometry Glossary everyday.
*We have a quiz tomorrow on lines and angles.

Polygon:  closed (all sides are connected), plane (flat) figure with straight sides (no curves!)
Right Angle:  an angle whose measure is exactly 90 degrees.
Acute angle: an angle that is less than 90 degrees. 
Obtuse angle:  an angle that is greater than 90 degrees but less than 180 degrees
Bonus:  straight angle:  a 180 degree angle (straight line)

line:  a straight path of two points that goes on and on in both directions
ray:  a part of a line that has one endpoint and goes on and on in the other direction
angle:  formed when two rays have the same endpoint

Yesterday we read The Greedy Triangle - you can read along here:  http://www.youtube.com/watch?v=kPuI4XyyZUE
