“To Infinity and Beyond!”

February 1, 2013

In the movie Toy Story, battery-run astronaut Buzz Lightyear thinks he can actually fly – and when he does try to fly, he yells, “To infinity and beyond!” So what is infinity, exactly? In math, infinity means that numbers just keep on going: no matter how big a number you can think of, you can always add one and just make a bigger number.  We’re sorry, Buzz, but there’s no way to go beyond infinity.  But as we look at some other milestone numbers, we’ll see that even non-infinite numbers can be pretty big and pretty cool.

Wee ones: What is the biggest number you can count to on your fingers and toes all together?

Little kids: What is the largest two-digit number?  Bonus: What is the largest three-digit number?

Big kids: While you may know “Google” as a search engine, there is actually a very large number called a “googol” that is a 1 followed by 100 zeroes!  How many more zeroes does this number have than in a thousand?  Bonus: How many more zeroes does this number have than in a million?

Wee ones: Count your fingers and toes!

Little kids: 99.  Bonus: 999.

Big kids: 97 zeroes.  Bonus: 94 zeroes.

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 while still in diapers, 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.
