Bedtime Math fan Sydney B. asked us, what’s the longest finger anyone has ever had? Read on to find out and do some “hands-on” math!
Have you ever wondered how much you’d need to eat if you ate just donuts, or just carrots, or just cake? For some foods, it’s a smaller amount than others. And an app called Calorific shows you just how much of some foods equal 200 “calories.” Read on to do the math and find out just how many donuts and carrots equal the same amount!
Canned food isn’t just for eating. Each year, people get together and build cool-looking statues out of them for an event called “Canstruction.” Read on to do the building math in playing with your (canned) food.
A palindrome is a word that is spelled the same backwards and forwards, like toot and racecar. Can you think of any others? It turns out numbers can...
Imagine being 75 years old… and still being the baby of the family. That’s what life is like for Eugenia D’Cruz, who has 11 older brothers and sisters!...
Sometimes you look at your everyday life and decide you need a change – a big change. And one way to get that is to repaint your bedroom. Lots of colors, lots of eye-hurting patterns – something that will make a statement.
If you could repaint your room, and could go as crazy as you wanted, what colors would you use? Of course, the fancier you get, the more carefully you have to plan.
When we drive on the road, we can’t all just go every which way. We have to stay on one side, and wait our turn where roads cross. Stop signs help, but really busy crossings need traffic lights. The traffic light, that cute red, yellow and green trio, was patented (made official as an invention) on this day in 1923. Actually, the very first electric traffic light was invented in 1912 by Lester Wire, a policeman in Utah fed up with all the traffic; you can imagine, after hundreds of years of slow horse-drawn carriages, what it was like to have this speedy, loud thing called a car suddenly show up. So Wire borrowed the idea of railroad signals to make a traffic light, which had just red and green for stop and go. Then in 1920, Detroit cop William Potts built one with 3 colors (red, orange and green). As you see here, people have tried other designs, like this funny dial one from Australia, but the three-color light is what keeps most of us from crashing into each other today.
Waffles are yummy no matter what shape they come in. But it must be a lot of fun to eat keyboard-shaped waffles – especially when there are so many square holes to catch the syrup! Read on to eat up the math in this funky invention.
Bedtime Math fan Arun W. just asked us a question we’d never thought about: how many Cheerios are in a box of Cheerios? Read on to find out, and add up the big fun in these little Os!
The New Year is a popular time to start “resolutions,” or promises to become a better person. But just how long does it take for that promise to stick? Read on to do the New Year’s math in resolutions!
