Here is a brief expaination of what the x-axis is from Mathworld.wolfram.com.
My favorite things to do with an x-axis was mapping coordinates and finding their slope. In 7th grade I took algebra I'd love to shade the different sides of the lines with my collection of highlighters.
Here some activities your kids can do.
- Make a map of a local park on a piece of graph paper or just make up your own map. Make the x-axis and y-axis and number them. Plot out trees and major areas of the park (playground, tennis courts, fountain, etc).
- Label the coordinates for them.
- Can you find the slope between two trees or park features?
- What is the distance between the most distant points (hint you may need to make a right angled triangle to figure it out).
- Take a corner of the classroom or standard corner. Distinguish which one will be the x-axis, y-axis, and z-axis.
- With a measuring tape, plot out one item in the room such as a desk. Here are some tips on xyz drawings. Drawing 3D shapes can be pretty fun.
