Perky Pack of Penguins

March 1, 2016

Penguins are those cute birds who waddle around on the ice, but swim as smoothly as fish. We’ve talked about their cool black and white coloring, but our friend and fan Jordan F. asked us, how many penguins are there in the world? (along with sending a great picture!) There are many “species” or types of penguins, and scientists have counted up some of them by taking pictures from way up in space. There are about 8 million chinstrap penguins, which is a great name for a penguin, and about 8 million adelie penguins. Then throw in 4 1/2 million king penguins, and almost 1 millionemperor penguins. Magellanic penguins, named after the explorer Magellan, number around 3 1/2 million, and southern rockhopper penguins with their funny feathery heads add another 2 million. But those are no match for the 18 million macaroni penguins! When you add in other species, it come to around 48 million birds…and a lot of cute baby penguin chicks each year.

Wee ones: If an iceberg has 8 chinstrap penguins and a rockhopper penguin floating on it, how many penguins is that?

Little kids: If we have 4 mama chinstrap penguins and each lays 1 egg, once the eggs hatch how many penguins do we have?  Bonus: If you add in their 4 dads, now how many penguins is that?

Big kids: If you add up just the 4 1/2 million king penguins and 3 1/2 million Magellanic penguins, how many penguins is that?  Bonus: Can you “spell” 48 million as a number, using digits?

The sky’s the limit: If you pick a few pet penguins, and you have twice as many king penguins as rockhoppers, twice as many emperors as kings, and 28 penguins in total, how many king penguins do you have?

 

 

 

Answers:
Wee ones: 9 penguins.

Little kids: 8 penguins.  Bonus: 12 penguins.

Big kids: 8 million penguins. The 4 + 3 give you 7, and the 1/2 + 1/2 give you another 1 million. Bonus: 48,000,000.

The sky’s the limit: 8 king penguins. If you have 2 kings and 4 emperors for each rockhopper, that makes a set of 7. Together 4 of those sets make 28 penguins total, and 4 sets will have 4 x 2 or 8 king penguins.
