Geometry
Lines, segments, rays
Grade Level
Expectations
•Identify and draw segments, rays, and lines
that are perpendicular, parallel, and
intersecting (G-5-E)
•Identify, describe, and draw intersecting,
horizontal, vertical, parallel, diagonal, and
perpendicular lines, rays, and right angles in
the real world (G-5-E) (G-6-E)
Big Idea
Geometry is everywhere! We realize
that different types of lines, line
segments, points, and rays do not only
exist on paper but in our world. We
see geometric figures like road signs,
buildings, houses, and other items in
our environment.
Guiding Questions
Can we identify and
describe the
characteristics of points,
lines, segments, and rays?
straight path that
goes on forever in
both directions
Parallel Lines
lines that
never cross,
even if they
are extended
Railroad
tracks
Intersecting Lines
lines that
cross at
one point
Perpendicular Lines
lines that form
square corners
(90’ angles)
where they cross
Write what each line shows.
Parallel lines, intersecting lines, or perpendicular
A.
B.
C.
Part of a line
with 2 endpoints
part of a line
having only
one endpoint
the point
at the end
of a ray
Draw a line to connect
the geometry word with
it’s real life picture
Where 2 roads cross

The things that
shine from the sun
window
Q-tips, cotton swabs
• Ray
Railroad tracks
Imagine you are an artist…
Draw a line. Don’t forget what
your endpoints should look like.

Great job!
Now you are a Geometry Genius!
As you can see, we can relate
geometry to things around us.
