Big-Jumping Bunnies

by Laura Overdeck

Horses are great runners and jumpers, and the best ones leap over fences in jumping shows. But a much jumpier animal now does this, too: rabbits! In this video, fluffy bunnies compete in rabbit show jumping. It’s hard to teach rabbits to do this: they aren’t as smart as horses, and have to stay on a leash so they don’t wander away (since they aren’t very smart). Sometimes their human friend has to “re-set” the bunny to a better spot to jump. But the winning bunnies make it over all 12 little hurdles. They also try to jump the highest and the farthest, with the world bunny long-jump record at almost 10 feet! Best of all, when you’re a big kid, you can try running the hurdles or jumping the long jump or high jump, too!

Wee ones: Bunnies have 4 legs. Get down on your hands and knees like a bunny, and pick up your back right leg!

Little kids: The checkerboard hurdle is the 4th one in the course. How many hurdles do the bunnies jump over before it? Bonus: If the 3rd bunny makes it over the checkerboard hurdle, then the 6th bunny, then the 9th, which bunny should make it next?

Big kids: The record-winning rabbit jump was 9 feet 10 inches. How far short of 10 feet is that? (Hint if needed: A foot has 12 inches.) Bonus: If each hurdle is 5 feet away from the next, how far does the bunny run from the 2nd hurdle to the 8th hurdle?

The sky’s the limit: If the bunny has just 5 hurdles left, and jumps only 2 of them, how many possible pairs of 2 hurdles could that be?

 

 

 

 

 

 

 

 

 
 

 

Answers:
Wee ones: Try to find your back right leg!

Little kids: 3 hurdles. Bonus: The 12th bunny.

Big kids: 2 inches short. Bonus: 30 feet.

The sky’s the limit: 10 pairs. There are 4 pairs that include the 1st hurdle (1-2, 1-3, 1-4, 1-5), then 3 new pairs include the 2nd hurdle (2-3, 2-4, 2-5), then 2 more include the 3rd hurdle (3-4, 3-5), and finally 4-5 is the last. So we get 4+3+2+1 = 10 possible pairs.
