Well done to everybody who found ways to make 18 using these dice in a corner. Kiran, Eeraj, Igla, Hassan and Ze-shaan from Crumpsall Lane Primary School in England investigated ways of making 18 using two dice:

Well done for finding so many solutions with two dice! The final picture is slightly unclear but this represents the solution:

2 4

Harry and Jack from Canberra Grammar School in Australia found four possible solutions using three dice:

Take a look at Harry and Jack's full solution to see their thoughts on this problem.

We received a solution from another Jack at Canberra Grammar School in Australia, who sent in these solutions for four and five dice:

Jack said:

I cannot show all pictures because the file size is too big!

That's a shame, Jack! I think there's one solution that nobody has found so far (that isn't just a rearrangement of one of the other solutions). If anybody thinks they have found it, please email us.
