A maths problem for you...that will come to fruition in the year 3183

Try this on your DCs!

An artist wants to celebrate the passage of time. They have 10 blocks and he is going to put them in a pattern.

4 blocks, then 3 blocks on top, then 2, then 1 - so 10 blocks.
The first block is put in position in 2024. Then every 10 years, another block is put down.

So the last block will go down in 2124 - after 100 years has passed.

Right?

I'm not sure what your question is?

But 10 blocks with 1 every 10 years takes 90 years not 100, as you start at time zero not at time 10.

If you watch the video, an artist is celebrating the passage of time in a town in Germany.

Laying 120 blocks over "1200 years" - with a plan to celebrate the last one in 3193. The first one was laid in 1993.

If you ask your DCs when the last block will be laid - or how many blocks do you need so you start in 2024 and end in 2124, it would be interesting to see what they say, especially if you say every 10 years and it's 100 years later - so get them thinking about 10 and 100.

Ah, I see, you mean will they make the same mistake?

It's set in stone and has already happened.
It's the fence post problem.

The last block will be put down in 2014 won't it?

So 90 years after 2024? (assuming you meant 2114?)

That's a pain for their centenary celebrations when they lay the last stone 10 years earlier!!

There is an inverse example also.

Hold up both hands and ask DC "How many fingers and thumbs do I have?". When they say "10!" take one hand and count down "10-9-8-7-6...." then hold the other hand up without counting it down and say "Plus 5 equals 11!"

Gets them every time.

I like that - playing with their mind.

I do wonder if the blocks will be around in 3183? I bet concrete won't be used - and who knows if the original blocks will still be in 1 piece?
