People who build the zoo walls really need to know how high animals can jump. A jaguar can leap 10 feet high off the ground, and some kangaroos can rocket 20 feet through the air. An anteater, though, isn’t quite as bouncy…he probably needs just a 3-foot fence. Other animals might climb instead, so their walls had better be slippery. Good thing the giraffes can’t jump!

*Wee ones:* Which is higher, the antelope’s 8-foot fence or the anteater’s 3-foot fence?

*Little kids:* If a 6-foot anteater that tries REALLY hard can jump 3 feet, and you can jump 1 foot farther, how far can you jump? *Bonus:* A red kangaroo can jump 25 feet. If the stream around his pen is just 2 feet wider than that, how wide is the stream?

*Big kids:* If a red kangaroo makes 3 25-foot leaps in a row, how many feet does it travel? *Bonus:* If the zoo divides a 50-foot-wide square into 4 equal square pens, with a fence all around, a fence running through the middle back to front, and another through the middle left to right, how much fence does the zoo need?

Answers:

*Wee ones:* The antelope’s 8-foot fence.

*Little kids:* 4 feet. *Bonus:* 27 feet.

*Big kids:* 75 feet. *Bonus:* 300 feet total: 200 around the edge, then a 50-foot piece across and another 50-foot piece back to front.
