Have you ever made anything out of clay? Clay starts out soft, and you can roll it, shape it, and carve designs into it.

Read on to see if the pieces of this masterpiece were able to be put back together – and do the math!

When a building isn’t the right size for what we need, we have some choices. We can add onto it, we can knock it down and build a new one, or we can just move to another building. Or you can just move the whole building, as one company did back in 1930. You can bet that required a lot of planning and math!
