Chalk Art Gone Wild! Try today's math challenge with your kids.

Have you ever drawn on pavement with chalk? What's awesome is that you have a ton of space and can draw huge pictures - much bigger than on a piece of paper. You can really go wild, like when over 5,000 kids together drew the world's largest chalk pavement art. Talk about huge: those little blocks in the corner of the photo are whole buildings! Drawn in Alameda, California in 2008, the record-breaking art was 90,000 feet wide and took just 15 hours, thanks to thousands of people pitching in. You could probably draw 20 square feet in an hour if you got on a roll.  Next time you go outside, you just might decide to turn your driveway into your own giant picture - at least until it rains.

Wee ones: If you're drawing one of the lizard's giant toes in the picture and 4 friends help you, how many of you are drawing that toe?

Little kids: If you helped out for 3 hours and started at 9 in the morning, at what time did you finally take a break?  Bonus: If that lizard has 4 feet and 4 toes on each foot, how many giant toes did they have to draw?

Big kids: If 5,000 people drew and each one used up 3 whole boxes of chalk, how many boxes were used?  Bonus: The chalk pavement art was 90,000 feet wide! If you yourself can draw 100 feet of width each day, how many days would it take you to draw the whole thing?

Answers:

Wee ones: 5 of you.

Little kids: 12 noon.  Bonus: 16 huge toes.

Big kids: 15,000 boxes.  Bonus: 900 days - which is almost 3 years.
