Geometry
Determining the Specifications for a Sloped Ramp
Grade: 9 - 10
Subject: Geometry
Curricular Goal: Student will be able to find volume, slope, and use
estimation skills.
Introduction:
The ADA of 1990, (subpart A Title III) prohibits discrimination on the basis of disability
by public accommodations. It requires that places of public accommodation and commercial
facilities to be designed, constructed or altered in compliance with the accessibility
standards established. Contractors and/or engineers must use geometry and other math
knowledge when making these accommodations. One accommodation that requires this
knowledge is the construction of wheel chair accessibility ramps. Mathematics is
used for finding the slope, volume, area, and distance of each ramp, It is also used to
find the amount of concrete needed and the price it will cost.
Task:
Research and design a handicap accessibility ramp using the appropriate
guidelines for public use ramps.
Process:
1. Find the ADA requirements for a handicap ramp.
2. Determine the dimensions that satisfy the regulations after you get
the information from your teacher.
3. Determine the mat formulas for finding the slope, length , height,
and volume needed in the ramp.
4. Sketch a diagram.
5. Determine the cost of the cement needed.
