It is important for students to know what happens to the coordinates of points when they are reflected over the x-axis or the y-axis. This activity enables students to use Cabri Jr. to develop this understanding.

Determine the speed of Pac-Man in different units based on their timing of him across the x-axis. This video describes the problem: https://www.youtube.com/watch?v=TGd49bz1Q2w&feature=youtu.be

This is a very brief site giving the name physicists use when referring to this axis, and its general orientation in the Cartesian system.

The students will use a "real" 3D coordinate system. They will have 3 axes at right angles, and a plane (the XY plane) that will be able to slide up and down the Z axis. The students will then be given several coordinates and asked to...

A brief refresher on the Cartesian plane includes how points are written in (x,y) format and oriented to the axes, and which directions are positive and negative. Then students learn about what it means for a relation to be a function...

Copper axes from the Bronze age. Not drawn to scale.

This collection of five middle school math lessons covers the topic of plane geometry, specifically the concept of slope. The first lesson introduces young scholars to plotting points on a Cartesian grid using a Geoboard. Lesson two...

Short quiz covering the coordinate plane, axes, quadrants, origin, and plotting points.

Learners investigate the ellipse equation. The tutorial examines intercepts, foci, sketching ellipses, major axes,and minor axes. Examples with detailed solutions are included.

In this activity, students will identify and record ordered pairs from a coordinate plane. They will examine symmetry about the axes, reflections, and symmetry in nature. They understand geometric concepts like area and perimeter, and...

How do you build a frog from a single cell? Learn how body axes are established and nerve tissue is induced in frog embryos.

This algebra lesson explains some important rules about zeros (where graphs touch or cross the x-axis).

This lesson from Purplemath.com explains how to find x and y intercepts then shows exmples.

[Free Registration/Login Required] In this lesson, students will learn the basics of the coordinate plane including quadrants, x and y axis, ordered pairs and the origin. A 5 question quiz is included to see if they get it.
