The Best French Fry

It’s hard to find someone who doesn’t like French fries. Who doesn’t want to munch on a hot, crispy, salty stick of potato? But not all fries are equal: there’s always a best – or biggest – French fry out there. The longest fry in the world was a curly fry that stretched 34 inches! That should be enough for dinner.

Wee ones: If you slice through a potato and look at the flat side you cut, what shape do you see?

Little kids: If you eat 3 fries with ketchup and 6 without, how many fries do you eat?  Bonus: If you dip your 2nd French fry in ketchup, then your 5th, then your 8th…which one do you dip next?

Big kids: How much taller than that 34-inch French fry are you?  Bonus: You can cut about 25 fries from 1 potato. How many potatoes do you need to make 100 fries?

The sky’s the limit: If 8 potatoes make 200 fries, and 12 potatoes make 300 fries, and 20 potatoes make 500 fries…what’s the pattern, and how many fries do 44 potatoes make?

Wee ones: An oval, or possibly a circle.

Little kids: 9 fries.  Bonus: Your 11th fry.

Big kids: Different for everyone…find out your height in inches, then subtract 34. Bonus: 4 potatoes.

The sky’s the limit: 1,100 fries. You take the number of potatoes, divide by 4 and tack on 2 zeros. Why? Because multiplying by 25 is like multiplying by 100 and then taking 1/4, since 25 is 1/4 of 100.
