Lesson Overview
Lesson Title:
Damaging Angles

Mrs. Cindy Nash (Primary)

Brief Description:
Learn about the relationship between supplementary angles in car accidents

Topics Introduced:
Transportation Engineering (need for guardrails)

Transportation, Distribution, and Logistics Curriculum Framework Components Addressed:
Transportation Systems/ Infrastructure Planning, Management and Regulation
Suggested Grade Levels:
9th Grade
10th Grade
11th Grade
12th Grade

Standards Taught:
12.4.6 Math 2006
12.4.7 Math 2006

Lesson Information
Learning Expectations:

Students will be expected to learn how geometry concepts influence their everyday life

Plan Of Action:

Students will use hot wheel cars and white boards to learn about linear pairs and supplementary angles.

Data Set Used:


Materials Needed:

Individual white boards placed on the floor, against a wall, or if you have non-carpeted floor, you can just measure the angles directly on the floor with tape

Hot wheel cars

Other possible option:

Use of a launch or ramp to start the cars

Preparation Period:

There is no prep period for this.  The students do everything you need.  If you want to show videos, you can search on You Tube or Teacher Tube.

Implementation Period:

One class period:

Five minutes drawing the angles onto the whiteboard

Ten to Twenty Minutes doing the chart and crashing the cars

Ten to Fifteen minutes going over the implications in the real world.

Science, Math, Engineering and / or Technology Implications:

The importance of quardrails on the sides of roads, and how the concepts of reflection angle, linear pair of angles and supplementary angles impact crashes.

Unexpected Results:

The students liked the activity, but they didn't like the fact that it dealt with math.  We need to do more things to show students that math can be fun.

Considerations for Diversity in Education:

No extra necessary considerations needed.
