Fascinating Coordinate Geometry Exercise

8 12 2012

Today Year 9 revised finding the midpoint of an interval, slope and equation of the line and its perpendicular.

I gave them a grid of their names and they worked with the student next to them, using their grid coordinates to answer the questions.

They said it was much more interesting than working from the textbook.

This is the file Student Coordinates I used to generate the names. Notice the tabs at the bottom. I generally use the 4 quadrants to make it a little more challenging for more able classes.

Another teacher shared it with me years ago. It is a real gem.
