How to play

  • Using the 5x8 (5 eights) grid standing tall, find the longest pathway you can, travelling along the lines of the grid from the top to the bottom of the grid.

  • Then, find the shortest pathway that you can find.

  • Your pathway can’t go along the side borders of the grid and you can't go outside of the grid either!

Watch the next video to find out what to do next.

What to do next

  • Turn your grid paper so it lays flat, so you can see a 8x5 grid (8 fives).

  • Can you make a longer pathway now that you have turned your grid paper?

  • Can you make a shorter pathway?

Finally, watch the last video.

Investigate further

  • Create different pathways that have exactly 12 steps.

    • How many pathways can you create that are exactly 12 steps?

  • Create different pathways that have exactly 15 steps.

    • How many pathways can you create that are exactly 15 steps?

  • Create different pathways that have exactly 30 steps.

    • How many pathways can you create that are exactly 30 steps?
