A Mini-Mini-Kangaroo

August 30, 2019

Kangaroos think big. They can jump 9 feet high in the air and leap more than 20 feet in one jump, right over a whole car. So what can a mini kangaroo do? Check out Scotty, the baby tammar wallaby here. He’s so small that he can sit in your hand or inside a shoe! He weighs only 10 ounces (about 3-4 candy bars), and drinks milk from an eye dropper. Over a million wallabies like him live on Kangaroo Island off the coast of Australia. Let’s do the math to find out how far they can jump!

Wee ones: Baby kangaroos start small, too. Who weighs more, a 5-pound wallaby or a 4-pound baby kangaroo?

Little kids: If you can fit 2 cute wallabies in each of your hands, how many can you hold all together?  Bonus: One pound has 16 ounces in it. How many more ounces does the 10-ounce Scotty need to gain to weigh 1 pound?

Big kids: If Scotty can jump 10 inches, an almost-grown-up kangaroo can jump 110 inches, and a baby kangaroo can jump the number halfway between, how far can the baby kangaroo jump?  Bonus: How many feet is that, and how does that compare to your height? (Reminder: A foot has 12 inches).

The sky’s the limit: If a growing kangaroo can hop 11 times as far as a wallaby and that’s 90 inches farther than the wallaby, how far can each one jump?
