The idea of a grade in the road is called the slope (known as rise over run, a bigger number means a higher or steeper slope of the surface compared to it being flat, or horizontal. Slopes are seen everyday in life; just recently our class studied trigonometric functions and finding the length of a side in a right triangle given an angle and the length of a side, or finding the angle of the slope and given the length of two sides, finding both solutions when plugged into the right equation.
Slopes can be found in our lives such as when we drive along hills, using less gas and simply letting the car go on its own when we have a steep hill, or using a lot when we go up a hill. The amount of slope or "grade" can also be seen directly at school as we occasionally have large thunderstorms, flooding our lower campus due to the gradual but large steepness of the school.
