When it comes to anyqs, I find that the ones that interest me the most are the images or videos that blow my mind by sheer scale. A seven wonders of the world sort of deal rings deep within my soul, and so I offer you MEGACOIN!
Act 1 - The Coin
HOLY CRAP THAT IS HUGE! Here is where I would ask "How much is this coin worth?" Let students ask questions. I am debating if I want to let them know it is made of pure Gold or should I let them follow any rabbit trail they want. They'll probably guess it's gold.
Act 2 - The measurements
There is a lot that goes on with this one. We have volume, density, rates, ratios, it is all fantastic!
Act 3 - The Reveal
And the final answer is...
I have actually been able to think of a few cool sequels based on this (which makes me happy since this is the hardest part for me).
- What could the dimensions for a true million dollar coin be? A billion dollar coin? A trillion dollar coin?
- Using the following chart, how much would this coin be worth today? Did the people that bought these make a good investment?
