What’s the biggest picture in the whole world? Well, the biggest drawing by 1 person, Ravi Soni, covers 6,781 square feet – about the size of a football field! But Canadian cyclist Stephen draws by riding his bike while holding a GPS tracker, which traces his path as a red line on the map. This makes miles-wide pictures of unicorns, dinosaurs and other doodles!

*Wee ones:* If you want your drawing to have 5 colors, and you have pink, blue, green, and yellow chalk, do you have enough colors?

*Little kids:* If your drawing of a purple and white tiger covers 2 rows of sidewalk squares with 4 squares in each, how many squares have you covered? *Bonus:* If it took Ravi 7 months to draw his huge pencil drawing and he started in March, when did he finish?

*Big kids:* If you take 11-inch-long sheets of paper and lay 9 of them end to end, how long a picture can you draw? *Bonus:* Which way do you get to draw more neon green giraffes: 4 on each of those sheets, or 6 on every other sheet starting with the 1st?

Answers:

*Wee ones:* Not quite — you have 4 colors, which is less than 5.

*Little kids:* 8 squares. *Bonus:* In October.

*Big kids:* 99 inches. *Bonus:* More if you draw 4 of them 9 times, which gives 36 giraffes; the other way you draw 30 in total (6 per sheet on 5 sheets of paper).
