The Cartesian Plane

Take graphing outside and make a giant coordinate plane to plot your human points. Young graphers are each given a coordinate for a particular shape and asked to make the geometrical shapes one by one. Those not plotted are to write down...

How do letters and numbers create a picture? Scholars learn to create input/output tables to graph functions. They graph both linear and nonlinear functions by creating tables and plotting points. 

Sal's goal in this video is to "familiarize ourselves with the x, y-coordinate plane." If your pupils have blank expressions when you present them with graphing problems, this video will be a great help to clear up the basics.

If your class struggles with graphing inequalities, or if your lecture could use some help from Sal, this video would be a great help. Sal's instruction is measured and patient, and viewers will walk away feeling more confident and...

So you have an ordered pair and you want to graph it. Just remember that the first value is plotted along the x-axis and the second value in the pair is plotted along the y-axis. So count left or right, then up or down and you have...

Find out what picture is hidden in this graph and work on coordinate graphing with this worksheet! Learners plot 66 ordered pair points on a Cartesian graph, then connect the dots to make a picture. This would work as an in-class...

Sketch graphs with the Graph Sketcher. Scholars graph functions on a coordinate plane. An interactive makes it as easy as inputting the function and clicking a button.

Just a couple of ways to look at some data regarding basketball free throw percentages for a specific player. Make a table and a coordinate axes graph. Plot the ordered pairs to get a nice visual to take a look at the data. Watch this...

Slopes are not just for skiing. Instructors introduce class members to the concept of slope and teach them how to calculate the slope from a graph or from points. The instructional activity also includes the discussion of slopes of...

Middle schoolers describe plotting functions on the Cartesian coordinate plane. They solve functions on paper and using an online tool to plot points on a Cartesian coordinate plane creating lines and parabolas.
