Geometry

Before Christmas the students began their Geometry Unit.  The students learned the definition for line segment and end points.  They made a cube and a pyramid out of gumdrops and tooth picks.  The gum drops were the end points and the tooth picks were the line segments.  The students wrote in their math journals to analyze the number of end points and line segments.
Here is the entry they completed in their math journal.
How many line segments does a square have?
How many line segments does a cube have?
How many endpoints does a square have?
How many endpoints does a cube have?
How many line segments does the star have?
How many endpoints does the star have?

The geometry vocabulary:
line segment  endpoint   parallel  intersecting
