Students struggle to remember which axis on a coordinate plane is independent and which is dependent. Here's a simple trick from the 6th grade teachers at Jackson Technology Center.
Just look at your hand! When you hold your hand in front of you, your thumb is independent of your other four fingers. Those four fingers tend to hangout together - you might even call them dependent.
Just like in the coordinate plane, dependent is vertical and independent is horizontal.
Thank you, Brenda, Megan and Katie for this "handy" trick. ;)
