Earlier this week, we continued our studies learning about line segments and rays. For this lesson we used two simple materials to complete the lesson. We used straws for the line segments, and paper for the points. 

First we cut four squares and labeled them a, b, c, and d. This represents the points that will be used in between each line segment. 
 

 

 
We then split the edges of each straw, and placed one "point" on the edge to create a ray.  
 
To create the line segment we placed another "point" at the opposite end of the straw. 

We continued this process until we created a rectangle, which we later used to learn about measuring the perimeter. In the process of creating the rectangle, we learned about perpendicular lines and parallel lines.  
 
 
After my son had created the rectangle, he then used the ruler to measure the perimeter. 



After measuring the perimeter, we then added the lengths of all sides and wrote down the process using "P" to represent the word "perimeter".
