Lots of kids like to draw for fun, whether with crayons or markers, fingerpaint or melted chocolate. The fun doesn’t have to end when you grow up, though. If you’re great at drawing, you can get paid to draw as your job! Look at Jim Paillot, who draws the pictures or “illustrations” in the Bedtime Math books. He gets to draw all day! He has drawn not only our books, but also dozens of My Weird School books as well as others. By the way, some drawings are more work than others. Spot art of just one animal or person. like the girl here from Bedtime Math 2, doesn’t take long to draw, but full page “illos” have to fill the whole page with color and scenery and more. When you add up all those books and the drawings on each page, you see quickly that drawing is not just great play, but hard work, too.

Real-Life Treasure Hunt

You never know what’s buried in your backyard, and for one California couple, their yard held real treasure. When they saw a can sticking out of the ground, they dug it out and ended up finding eight cans filled with 1,427 gold coins! The mix of $5 coins, $10 coins and $20 coins was minted (made) between 1847 and 1894, back when Americans used coins for those amounts. If you add up all those $10s and $20s, the coins have a total face value of almost $28,000. But they are worth far more than that, because the older a coin, the fewer of that coin we still have, and so the more that coin is worth. One of the coins is worth over $1 million all by itself, and all together the collection is estimated at $10 million. So what do you do when you suddenly find $10 million of coins in your backyard? Bury them again, of course! But just to be safe, they picked a new spot.
