Short Description

In this exercise kids will learn to give exact orders while moving each >others through the grid.

Preparations

  • Print the empty grid for everybody
  • Print the example grid for everybody
  • Prepare grid in the class room floor with tape or string
  • Choose obstacles (they can be what ever that fit to the square of grid)
  • Plan few different grids with obstacles

Script

Planning the route

  • Give students the example grid paper
  • Instruct them to write or draw instructions to the paper (if drawn they can do it with arrows for example)
  • Instructions They can use are: Move forward, Turn left or Turn Right

Testing the route

  • After planning the route let students try their route in the grid made to class floor
  • Alternatively they can draw the route with pen to their own paper or on a blank example grid
  • If they find bugs they can fix them and try again

Designing new grids

  • After Testing their route students can design new places for obstacles and test their route plan again
  • Usually after this the old route doesn't work anymore, so they have to plan new one

Questions to think

  • Is there impossible grids?
  • Is some plan invincible?
  • How could the plan be made better? (could we use conditions?)
