The first instance of Drawing lines is located in the 4th grade (U.S.) Math Mission. This exercise uses an interactive geometry sketchpad to understand lines, rays, and line segments.
Types of Problems
There is one type of problem in this exercise:
- Draw the situation: These problems asks the student to use the interactive pad to draw a situation involving lines, rays, and line segments. They are also expected to answer a question about endpoints and direction of these geometric objects.
This exercise is easy to get accuracy badges because the instructions are clear and the manipulative is well designed and usable. Speed badges are hard because the user has to be fast with moving and clicking.
- The questions are only three types.
- A line has no endpoints because it extends infinitely far in two directions.
- A ray has one endpoint and extends infinitely far in one direction.
- A segment has two endpoints and so it has a finite length and extends infinitely far in no directions.
- Map makers use rays, lines, and line segments to draw streets and roads on maps.
