# Drive Your Own Lego Car!

Guess what: now you can drive a Lego car just like little Lego people do, and without having to wear those snap-on pants. Raul Oaida built a real human-sized car out of Lego! He used half a million Lego pieces, and the car can drive up to 20 miles per hour. But what if you made another vehicle out of your own favorite toy?

Wee Ones: What shape is a car tire?

Little Kids: If the 10th piece in the side door is black, how many yellow pieces come before it?
Bonus: If the 12th piece is black in the next row, then the 14th piece in the next, then the 16th in the next…which piece is black in the next row?

Big Kids:  The car uses 500,000 pieces. If each of the 2 doors uses 100,000, how many are left for the body of the car?
Bonus: If the windshield uses 24 Lego windshield pieces with 6 pieces across in each row, how many rows tall is it?

Wee Ones: A circle (or in 3D, a “torus”).

Little Kids:  9 yellow pieces.
Bonus: The 18th piece.

Big Kids: 300,000 pieces!
Bonus: 4 rows tall, since 6 x 4 = 24
