You’ve got to love this video of puppies skidding down the hall towards their food bowls. The 2 golden retrievers run down the same hall over and over — except they’re shown doing this about every 3 weeks. So through the video we see the puppies grow, and get a little better at rounding the corner without crashing. At 46 weeks (about 11 months old), the puppies are almost full size. Grown-up goldens stand about 24 inches tall and weigh about 70 pounds. But the pups are still “teenagers” agewise: they still don’t know how long their legs are, and trip over their goofy feet. Somehow, they still make it to dinner.
Wee ones: Point to the puppy on the left in the picture. Now point to the puppy on the right!
Little kids: How many big paws do those 2 puppies have together? Bonus: If the puppies had romped on camera at 11 weeks, then 14, then 17…what week number would have been next?
Big kids: The video filmed the puppies from the end of 11 weeks until the end of the 46th week. For how long were they filmed? Bonus: A dog’s age in “dog years” is 7 times the actual time they’ve lived, since they live shorter lives than we do. How long is 11 months in dog years and months?
Wee ones: See if you can tell your left from right.
Little kids: 8 paws. Bonus: 20 weeks, because they’re all 3-week jumps.
Big kids: 35 weeks. Bonus: It’s 77 months, which is 6 years and 5 months.
Laura Bilodeau Overdeck is founder and president of Bedtime Math Foundation. Her goal is to make math as playful for kids as it was for her when she was a child. 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.
