6 Numbered Cubes

Cubes Banner


You'll need a set of six same sized cubes and some labels to number them 1 to 6. They'll be joined face to face as these two examples show.

You might begin exploring by putting them in a staircase like this:

The main thing to try is to add up the numbers that are visible as you walk around the staircase without moving any of the cubes. This staircase above gives a total of 78 - do you agree?  How did you count?

The exploration may begin with finding the staircase arrngement that would give the highest number and then the lowest number.

You could then try other shapes like the two at the top, each time searching for the highest and then the lowest.

What arrangement of what shape gives the highest/lowest possible?

You can extend the exploration by changing one of the rules and investigating further.



We'd love you to share how you've tried this and what you've discovered. You can add a comment below, or you can email us - your work may be featured in the showcase.


How does it work?

Probably best to read through a couple of times considering what each sentence means and if you are still stuck then reply to this with a question.

She sent in a lengthy pdf that is worth while looking at and it's published at https://nrich.maths.org/10918?part=solution.
