The topic Measuring segments appears under the 7th grade (U.S.) Math Mission. This exercise connects the numerical concept of length to the geometric concept of segment using a number line.

Types of Problems

There is one type of problem in this exercise:

  1. Find the length of the segment: This problem has a number line with four labeled points. The student is asked to find the length of the segment that connects two of the given points.

    Find the length of the segment

Strategies

Knowledge of absolute value representing length reinforces the idea of this problem, but is not necessary to complete it.

  1. The length of a segment is the distance between it's endpoints.
  2. The distance between two points on the number line is the absolutely value of the difference between those points' coordinates.
  3. Another way to find the distance (which is faster on shorter lengths) is to manually count the number of spaces between the endpoints.


Real-life Applications

  1. Measurements are used for many things, such as cooking, and for placing carpet.
