Parallel lines are always the same distance apart and never meet.



We use arrowheads are used to show that lines are
parallel.
See how these lines have one arrow the, because these ones are also...

In this video we look at more examples of plotting straight lines onto graphs. This time the equations are a little trickier - such as having fractions for the gradients. When completing the table of values, if the equation has fractions...

This visual math puzzle, or math logic puzzle as some teachers call it is perfect for grades 3, 4 or 5. I loved to use these math warmups before class every day to encourage students to start thinking mathematically and to share their...

There’s a deep connection between gravity and time - gravitational fields seem to slow the pace of time in what we call gravitational time dilation. And today we’ll explore the origin of this effect. And ultimately, we’ll use what we...

Physics progresses by breaking our intuitions, but we’re now at a point where further progress may require us to do away with the most intuitive and seemingly fundamental concepts of all—space and time.

Michael Jordan's legendary slam dunk from the free throw line has been calculated at 0.92 seconds of pure hang time. But how many seconds could Jordan have gotten were he doing the same jump on Mars? Or Jupiter? Andy Peterson and Zack...

Today's math curriculum is teaching students to expect -- and excel at -- paint-by-numbers classwork, robbing kids of a skill more important than solving problems: formulating them. Dan Meyer shows classroom-tested math exercises that...

If you've ever taken a science or math class, you've probably seen the name "Bernoulli" -- and maybe you assumed it was one person, but that family had a squad of mathematicians.

Understanding the 8 times table! In this video, we’ll explore patterns, use a number line, and discover real-life examples that make learning multiplication meaningful and fun. This approach focuses on understanding—not memorization....

In this math video we will use a relationship to graph a line. We will interpret the real world situation given as an ordered pair (x, y). We will use the unit rate ( or slope) to create and write ordered pairs. We will plot the points...

In this video, the teacher explains how to use the vertical line test to determine if a graph represents a function or not. They go through four examples and also show how to find a missing value in a table to make it not a function. The...

In this video, the teacher explains how to use the vertical line test to determine if a graph is a function or not. The viewer is presented with four graphs and asked to identify which one is not a function. The teacher demonstrates...

The video is an educational lecture on line charts and their use in visualizing time series data. The presenter explains how line charts are primarily used to display data with time as one of the variables, and demonstrates how to read...

Draw a line plot of the volume measurement of liquids found in the school’s laboratory and answer questions about them.

In this video, Mrs. C demonstrates how to add positive and negative numbers using number lines and provides clear rules for adding integers without the need for a number line. By following these rules, students can easily determine the...

Suppose we want to count the number of brothers and sisters each student has in John's class and then represent the information in a line plot.

This video explains how to determine if a relation is a function using mapping diagrams, tables, and the vertical line test. The lesson covers the concepts of inputs and outputs, ordered pairs, and the definition of a function as a...

In this video, the teacher explains how to write equations of lines in point slope form using a given point and slope or two given points. The video also covers how point slope form relates to slope and how to convert point slope form to...
