Here is one way to use the applet as a whole class activity.
  • Show this applet on the screen.
  • Students try to remember the positions of the ships before they are hidden.
  • Teacher hide the ships. Turn on the axes with or without grids. (Use the top right Style Bar.)
  • On this blank coordinate plane, students start suggesting points that may 'bomb' the ships. Coordinates can be entered in the Input Bar at the bottom.
  • After some trials, show the ships and discuss the results.
  • Attention can be put on describing and comparing the points or their relations.
