Act One:

The world record for the tallest structure made of Legos was set in Seoul, South Korea.  Check out the pictures and video below:

How much do you estimate that it costs for only the materials, to build this tower?

What other questions do you have?

Act Two: What information do you need











Here are some Lego prices from Amazon that you can use to figure this out.

As you come to an estimate, make sure that you show your thinking and process so that it is clear to other.  Teachers - you may consider having students create posters that show how they came to an estimate or consider showing different ideas through a document camera.
