Even though there’s only 1 cat and 4 deer in this picture, all the animals look confused and a little suspicious. It makes sense that the little cat would be nervous. While cats typically weigh 8-12 pounds, deer can weigh 150 pounds. And both animals have a top speed of about 30 miles per hour. The real question is, which one can rule the world? A deer can have 1 to 4 babies in a year, while cats can have up to 12 kittens per year. In the end, cats might take over!
Wee ones: How many animals can you count in the photo?
Little kids: If a deer and a cat try to race, how many legs do they have together? Bonus: Deer antlers can grow 1 inch per day. If you grew an inch a day, how tall would you be 1 week from now?
Big kids: If the lead deer weighs 200 pounds and the cat weighs just 12 pounds, how many pounds heavier is the deer? Bonus: How many cats that size would have to get together to outweigh the deer?
Wee ones: 5 animals: 4 deer plus the cat.
Little kids: 8 legs (4 on each). Bonus: Different for everyone…add 7 to your height in inches.
Big kids: 188 pounds more. Bonus: 17 cats, since 16 cats will weigh just 192 pounds.

Her mom had Laura baking before she could walk, and her dad had her using power tools at a very unsafe age, measuring lengths, widths and angles in the process. Armed with this early love of numbers, Laura went on to get a BA in astrophysics from Princeton University, and an MBA from the Wharton School of Business; she continues to star-gaze today. Laura’s other interests include her three lively children, chocolate, extreme vehicles, and Lego Mindstorms.
