Due to the animations not being supported, this presentation needs to be download to view clearly. During lesson students should have a copy of slide 4 and 13 to construct the maps themselves. This is very challenging, but students loved it! Give plenty of think time and try teaching techniques such as think-aloud, student collaboration, student lead teaching, and math talk moves. Encourage them to think BIG!

1. Objectives
Review: properties of line segments and angles.
Finding missing angles.
Constructing and labeling diagrams of angles.
Materials:
3 page handout
Pencil
4 colored pencils
Protractor

2. Pop vocabulary lesson on adjacent angles.
Adjacent angles have a common side and a common
corner point, the vertex point.

3. Follow the clues to graph and
discover missing angles.

Ms. Richard
If Landon walks on Blanco street and Preston walks on Cedar street, will
their paths ever cross?
Preston leaves his house and walks east along Lake street he then turns north on
Cedar what angle turn did he make?

20. Highlight the acute,
obtuse and right
angles in different
colors
The acute angle of Preston’s house and Lake st. is 30
degrees. Solve for the missing angle in the right triangle.
Estimate: Which angles on the map could be 65 degrees
Lake
Cedar

Ms. Richard
Draw a straight line from Preston's house to Landon's
house. Label it Berry Ave.
How can the triangle be
classified?
Preston’s
Landon’s
Do you see a triangle?
Legend
Highlight it and enter
information in your Legend.

21. Highlight the angle
between Carmichael
and Cori.
What kind of an
angle is it?
Question # 1

22. On Saturday
Jordan leaves his
house and walks
northeast on Arrow
street. Amanda
leaves her house
and walks northeast
on Carmichael.
Will they ever cross
paths?
Question # 2
Parallel

23. Are Pleasant and
Arrow street
perpendicular?
Are Pleasant and
Carmichael street
perpendicular?
Question # 3

24. What is the measure of
missing angle in the right
triangle?

25. Question # 5
Find the angle of
Amanda’s back
yard. The angle
with the “?” mark.

26. Bonus!! What other angles can you find!! Take a
close look . Label the new angles on your map.
Find the angle of
Amanda’s back
yard. The angle
with the “?” mark.
