Cookie Mining

Yesterday as a wrap up to our unit on minerals we used cookies to explore the economics of mining.

Carefully removing the topsoil, and vegetation before mining for chocolate chips.

Carefully mining.  The tools are expensive to replace. 

Complete focus.

My miners are all hard at work.

They could purchase up to 5 minutes to mine.
They understood the value of those 5 minutes.

Will the extra money be worth the investment?
