Potato Head Gets Ahead

Have you ever played with a Mr. Potato Head toy? You stick colorful body parts – arms, ears, eyes, nose, mustache, mouth, shoes, hat, and pants – into a potato shape, and make all kinds of silly faces. You can also set a world record. One kid named Matilda put together a Mr. Potato Head in less than 6 seconds, beating the old record! 


Wee ones: If you put 2 arms, 2 ears, 1 nose and 1 mouth on Mr. Potato Head, how many parts is that? Count them up! 


Little kids: if you make a wacky Mr. Potato head with 3 arms, 5 noses and 2 mouths, how many more noses than arms does he get? Bonus: Matilda also wants to set the record for putting together Mr. Potato Head while blindfolded. That record time is 15 seconds. Count down from 15 to see how quick that is! 


Big kids: When Mr. Potato Head was invented, the kit only cost $0.98, but you had to supply your own potato – really! If you bought 1 kit with a $5 bill, how much change would you have left to buy potatoes? Bonus: Mr. Potato Head once got 4 votes to be the mayor of Boise, Idaho. If the winner got 130 times as many votes, by how many votes did the winner win? 


The sky’s the limit: If you’re racing to put 1 arm, 1 eye, 1 nose and 1 mouth on Mr. Potato Head, in how many orders can you stick them on? Example: arm-eye-mouth-nose is different from eye-arm-mouth-nose… 

Answers:

Wee ones: 6 fun potato parts. 


Little kids: 2 more noses than arms! Bonus: 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1! 


Big kids: $4.02. Bonus: 516 more votes, since the winner got 520 votes. 


The sky’s the limit: There are 4 x 3 x 2 x 1 = 24 ways. The short way: if you had just 3 parts, each of the 3 could go first, leaving 2 choices for the 2nd spot (AE, AM) and then just 1 choice for the last (AEM, AME). There are 3 branches like that, so it’s 3 x 2 x 1. A 4th part makes 4 of these full sets of 6. Now the long way, which looks like Wordle: AEMN, AENM, AMEN, AMNE, ANEM, ANME (that’s your first branch of 3 x 2 x 1), EAMN, EANM, EMAN, EMNA, ENAM, ENMA, MAEN, MANE, MEAN, MENA, MNAE, MNEA, NAEM, NAME, NEAM, NEMA, NMAE, NMEA.
