 Refresher
The purpose of this section is to provide you with some resources to review in preparation for the lesson ahead. These resources may include videos, interactive applets, mini-lessons, and flash games to help you recall previously learned concepts. You can use these resources either before or after you try the questions in Are You Ready? Your teacher may also direct you to this section to review specific concepts.
In earlier lessons of this module, you mainly worked with the first quadrant of the coordinate plane. In this lesson you will be working with all four quadrants.
Complete the following game to see if you are ready.
The “Maze Game” activity allows you to practise point-plotting skills by moving a robot through a mine field to a target location.Go to “Quadrant” at the Mathematics Glossary website to review the definition of a quadrant in the coordinate plane. You will also be able to see how the quadrants are named.
