Thanks for visiting NZMaths.
We are preparing to close this site and currently expect this to be in June 2024
but we are reviewing this timing due to the large volume of content to move and
improvements needed to make it easier to find different types of content on
Tāhūrangi. We will update this message again shortly.

Students use their knowledge of cartesian coordinates and linear equations to pop bubbles with a laser. The bubbles have integer values which the student sums to score points.

The student is given a starting point for a 'laser' and is asked to enter coordinates for a finishing point. The goal is to choose a point that means the laser pops as many positive bubbles and as few negative bubbles as possible.
Only the positive quadrant of the coordinate plane is used.
