July 11, 2017 9:00 am

Hold on to your happy meals, because math is about to take lunchtime to a new level. Take a bite out of tanwiches (tangram sandwiches) in this tasty activity!

Cool Summer Fun with Sponge Balls

July 14, 2014 8:00 am

Water balloon battles are great fun, but I like to “green” our family whenever I can. That’s where sponge balls come in. They provide cool splashtastic fun, just like water balloons, but can be re-used and won’t leave bits of latex all over the grass. And they’re easy to make!

Crazy Dogs for Mealtime Math Fun

June 30, 2014 8:00 am

You know we’re always looking for good reasons to play with our food, so here’s an easy way to add zing, and math, to a simple summer meal. All you need to get going is a pot of hot water, 20 or so strands of spaghetti, and a package of hot dogs or brats!

Edible Optics: Make Your Own Magnifying Lens

February 27, 2014 8:00 am

Watch it wiggle, see it jiggle. What is it? It’s an edible magnifying lens! You can mix one up with the packet of gelatin that’s already in your pantry, but it looks best when made with clear (and alas) flavorless gelatin.

Count on a Great New Year’s Eve

December 27, 2013 8:00 am

When my boys were young, I started a tradition of doing a family art activity* on New Year’s Eve. Our inaugural project was making a kind of winter count. A winter count isn’t a math competition, rather it’s an activity borrowed from the Lakota tribe in which they record tribal records and significant events from the year. Some winter counts have a single image depicting the most memorable event of that year, though others have more. These images were combined with oral histories to provide a record of the past.

Track Santa’s Journey Through the Night Sky

December 23, 2013 8:00 am

As a child I scoured the night sky on December 24 looking for Santa and his reindeer. My dedication paid off. When I was seven, I saw their dark shadows crossing a moonlit sky. Really! Nearly forty years later I remember the thrill of spotting the sleigh and calling members of my family to the large picture window in our living room so they could see, too.

Fun Fibonacci Holiday Cookies

December 9, 2013 8:00 am

Baking is a great way to get kids measuring and understanding fractions, but these cookies pack an extra math punch. I like to say that these fun cookies put the “fib” in Fibonacci based on their cool spiral pattern, that is close to, but not quite a famous spiral. They’ll also impress your guests, and they’re easy to make with young bakers.

Go Nuts for This Easy Thanksgiving Treat

November 25, 2013 8:00 am

As I was pondering Thanksgiving desserts beyond pie and beyond pi (because we should have more than 3 options for such a bountiful meal), I realized that with a few tweaks, I could turn a favorite Chanukah treat into a new Thanksgiving tradition. This is fitting given the unusual overlap between the two holidays. Thus, my edible marshmallow dreidels are now edible acorns. The faux acorns resemble spinning tops, so I suppose they can double for dreidels on this double holiday.
