Lesson 4 Points and Lines All Around
Let’s find parallel and intersecting lines all around us.
Warm-up Which One Doesn’t Belong: Four-sided Shapes
Which one doesn’t belong?
Activity 1 Spot Lines and Line Segments
Here is a map of a neighborhood in Staten Island, New York.
On the map, find and label the following items:
4 line segments of different lengths
3 pairs of parallel lines
2 pairs of lines that are not parallel
(Consider using different colors for the different types of lines.)
In the words WHALE and JOY,
which letter has:
No parallel segments?
Exactly one pair of parallel segments?
More than one pair of parallel segments?
Only one segment?
If you have time… Which does the uppercase alphabet use more: parallel segments or intersecting segments?
Activity 2 Draw and Design with Lines
Draw a sketch of a part of our classroom and be sure to include:
at least 3 pairs of parallel line segments
intersecting line segments that make square corners
intersecting line segments that don’t make square corners
Trade sketches with a partner and find the specified lines in each other’s sketches.
Here are some symbols and logos that you may recognize. All of them have intersecting and parallel line segments.
Design a logo with at least 8 parallel segments and 8 intersecting line segments.
Use a ruler for any straight parts of your logo.
Which segments of the letter Z are a pair of parallel lines? Draw the lines.
Sketch a line that is parallel to the third segment in the Z.
