With Halloween just a week away, lots of us have decorated our homes for the big day. And if you’re a little creeped out by all those giant spiders and webs on people’s bushes — even though you know 3-foot-wide spiders probably aren’t real — you can try glowsticks for something a little less yucky and a little more colorful. No matter what you use to decorate, though, there’s sure to be lots of math!
Running a zoo is a lot of work: feeding all the animals, scooping their poop, and keeping critters from chasing (and eating) each other. For that last one, building the zoo is an even bigger project. You’d be amazed at just how high some of those animals can jump – and how high those fences have to be!
100 is a great number, and it’s even better if it’s your age — and you’re a math teacher. Madeline Scotto just turned 100 years old last week, and is still working 3 days a week as a math-team coach. It just goes to show that it’s fun to play with numbers at any age.
We’re loving the site Papermatrix, where super-talented people show us how to weave strips of colored paper into wild-patterned boxes, balls, and other shapes. And these cool crafts have a ton of math in them.
Of all the animals who blend into what’s around them using shape and color, the leaf-tailed gecko might be one of the coolest. It lives on the island of Madagascar, and looks just like the way it sounds: with a tail that looks like a leaf. And that’s not the only cool thing about it.
Soccer balls are fun to kick around and do cool tricks with. There’s lots of math in soccer balls, too, like the different shapes on them. It’s one sphere that’s full of surprises.
If you’ve ever played with a calculator, you might have seen that some screens make the numbers using all straight lines, and those numbers look like letters when turned upside down. But even when they stay right side up, numbers made of sticks give you all kinds of games to play.
There are about 320 million Americans – right now, at least. But how many have we ever had? This isn’t the easiest number to figure out. In 2011 one group did just that, though. And the numbers may shock you!
If you live in America, you might want to carve a pumpkin for Halloween, or at least roll a couple onto your front lawn for decoration. Well, you’d better get your muscles in shape if you’re buying your pumpkins from farmer Keith Edwards, who’s grown 7 huge pumpkins that together weigh over 7,000 pounds!
When animals hunt for food, sometimes they bite off more than they can chew. That seemed to be the case with this eagle. Luckily a fisher nearby happened upon the eagle to help it out.
