From Dinosaur to French Fry

October 11, 2018

When you think of a potato, you probably picture a brown, boring lump. But not all potatoes look like that. Just ask our fans Parker and Kenley M. Their family farm grows thousands of potatoes, and as you see here, some of those lumps grow into really great shapes like hearts, hands, ducks and dinosaurs. Since the kids see potatoes all day and night, they asked us, how many potatoes would it take to feed the world? Well, mashed potato recipes tell us to cook 1/2 pound of potato per person, which works out to be 1 potato each. So 8 billion people need 8 billion potatoes for that one meal. Turns out that we each eat about 69 pounds of potatoes each year…the question is, how many of those look like ducks?

Wee ones: When you slice through a normal-shaped potato (or look at it from the end), what shape do you see?

Little kids: Potatoes can be brown, red, or golden. If you have 2 potatoes of each color, how many potatoes do you have?  Bonus: If 2 of those potatoes are dinosaur-shaped, how many aren’t?

Big kids: If a regular potato weighs 1/2 pound, a duck-shaped potato weighs twice as much, and a dinosaur-shaped potato weighs twice as much as the duck, what do all 3 weigh together?  Bonus: If you eat 2 potatoes each week, and every 6th potato starting with the 6th is duck-shaped, in what week will you eat your 3rd duck?

The sky’s the limit: If each of the world’s 8 billion people eats 69 pounds of potatoes this year, how many pounds is that – and how many potatoes? (Trick for multiplying: 8 is 2 x 2 x 2, so you can just double the number 3 times! Another trick: what if it were 70 pounds a year, and how different would that be?)
