Hi, I'm Rachel, and today we're going to be going over teaching lines and line segments for the third grade. So a line is something that goes on forever in both directions that's straight, a straight line that goes on forever in both directions, whereas a line segment does not. It ends. A line segment we can define, that should be a straight line, as the shortest distance between two points. It is not just one point. It's important to define also what one point is, but a line segment is connected by two points and it's important that the third graders understand that it's the shortest distance between two points because a line is not like that, right, that's like a very long way to get from point A to point B, right, it's very confusing. A line is just the shortest distance like that. And it's a line segment when it has these two end points here and it's a line when it goes on forever. So it's nice to show them you know, in a figure like a triangle, right, these are made up of all line segments, but if you are graphing a line on a graph and it goes on forever, this is a line because it goes on in both directions forever, not a line segment. It's also good to show a ray which goes on in one direction forever but it starts from a point. So it's kind of like in between a line and a line segment. I'm Rachel and thank you for learning with me today.
