June 11 is Corn on the Cob Day, a great time to celebrate a very math-y food. The kernels are actually seeds, and every ear of corn grows an even number of rows. Most ears have 16 rows, which hold 800 kernels in total. We use corn to make more than 3,500 things, including cereal, peanut butter and marshmallows. The starch is also used to make fireworks, glue, and batteries. Very cool, but the foods sound yummier.
Lace up: Corn can grow in many colors: purple, green, blackish, bluish, red, white, and of course yellow. How many colors is that?
Jog: A number is even if it can be cut into 2 equal parts. What numbers from 1 to 10 are even?
Sprint: If an ear of corn has to have an even number of rows, can it have 15 rows?
Hurdle: If you eat every 3rd row of corn as you go 1 full time around a cob with 16 rows, at most how many rows can you eat without passing where you started?
High Jump: A bushel (8-gallon barrel) of corn holds enough sugar to sweeten 400 cans of soda. If you drink 1 of those cans, how many cans are left?
Answers:
Lace up: 7 colors.
Jog: 2, 4, 6, 8 and 10.
Sprint: No, because 15 isn’t even.
Hurdle: 6 rows at most: rows 1, 4, 7, 10, 13, and 16.
High Jump: 399 cans.
