You know how movies (like Lord of the Rings) have special extended editions. Jenn blogged on “My Homeschool 101″ about decimal street idea and then created her own special extended edition of it.

She called it, “an extended version teaching place value to the trillions.”

Decimal Street (special extended edition)

“I made blue comma cards with the names of the lakes that they use with it to teach extended place value.”

526,767,081,196

You would need a LOT of blocks to build that number
