Is that a drum solo? Or the sound of a massive stampede? YOU decide when your buffalo finger puppet performs on this awesome drum set! It took a little work, but we figured out how to get this entire drum set on a single sheet of paper. Just cut, color, fold, and rock out!

We recommend reading Teach Your Buffalo to Play Drums, written by Audrey Vernick, and illustrated by Daniel Jennewein (Balzer + Bray, 2011). From the first time you brought that baby buffalo home, you knew he was destined for great things. So order a drum set and wait for the magic (and don’t forget a couple cases of earmuffs for the neighbors)!

You’ll need:

First, cut the drum set from the template. It will looks like this…

drum set step 1Decorate it with markers, and don’t forget to write the name of your band inside the circle of the bass drum! When you’re done coloring, flip the drum set template over:

drum set step 2Roll the lower drums inwards, and tape them to the back of the set.

drum set step 3Next, fold the tabs downward along the dotted lines. These are your drum heads. Use scissors to shape them to the tops of your drums, then secure them with tape.

drum set step 4Repeat the same process with the upper drums.

drum set step 5Now fold the long base of the drum set upwards, tucking the cymbal stands between the lower and upper drums.

drum set step 6Turn the set around, and stick small tape loops to the tops of each cymbal stand. Pinch two circles of tin foil onto the tape loops. Your cymbals are ready, and your drum set is done!

drum set step 7Use scrap paper from your template to fashion a pair of drum sticks and finger loops. Tape the sticks to the finger loops, and slide them over your fingers.

drum sticksFinally, your buffalo drummer! Cut and color the buffalo finger puppet from the template (or use the full color version here). Cut finger holes in the chest. Then ready your drum sticks, step behind the drum set, and JAM!

It’s Tambourine Time

it's tambourine timeThe credit for today’s simple project goes to my 6-year old daughter! She told me she wanted to make a tambourine, scrounged through art supply central at home, and came up with this a few minutes later.

4 things I like about this project: 1) Unlike the paper plate versions, this tambourine uses a plastic oatmeal container lid that won’t buckle or tear; 2) The surface of the oatmeal container lid makes the instrument sound more drum-like (and thus more like a real tambourine); 3) The bells are threaded through pipe cleaner pieces and attached with tape. This made it possible for her to make the project with zero adult assistance; Finally, 4) My kid’s a crafter! SUCH a proud mom right now.

Inspired by her project, I developed a slightly fancier version. It is a little more work, but the threading part of the project really helps build those fine motor skills.

finished tambourineYou’ll need:

  • 1 large oatmeal or yogurt container lid
  • 3 jingle bells
  • 3 pieces of pipe cleaner
  • 2 ribbons
  • Hole punch
  • Tape

First, punch 7 holes around the perimeter of an oatmeal or yogurt lid. Thread the ribbon through the holes, ending with all the ribbons meeting in the bottom-most hole.

tambourine ribbonsQuick hint for threading floppy ribbon through holes…create a “needle” using masking tape. When you’re finished, just unwrap the making tape, or cut it off the ribbon entirely.

masking tape needleThread a jingle bell onto a piece of pipe cleaner, fold it into a U, and and insert both ends into a pair of holes. Unfold the ends of the pipe cleaner and secure them to the back of the lid with tape. Repeat these steps with the remaining 2 bells.

A Day in Digitopolis, Part II

Radiance by Matt ElsonWho knew infinity could be so beautiful? I’ve returned with Part II of the Digitopolis event post (Part I can be found here) and thought I would start it off with one of the stars of the show! The above image was taken inside an Infinity Box, one of multiple creations by Los Angeles-based artist, Matt Elson. Matt’s boxes have been exhibited at colleges, science centers, festivals, and museums. He generously loaned us two (titled Radiance, and You & Me Together) for our math event.

You and Me Together by Matt ElsonThe boxes are designed to be infinite, interactive environments that play with your perception and inspire inquisitiveness and wonder. They were in constant use during the event, and there were lots of shrieks of amazement, enthusiastic explosions of “Cool!” and long, drawn out utterances of “Woooooow…”

infinity marissaDigitopolis was not without its celebrities, including the King of Numbers himself. I speak, of course, of the Mathamagician.

mathamagiciansThat’s real-life mathamagician Brent Ferguson on the right, grinning away under the pointy hat covered with equations. He’s math faculty at the Lawrenceville School, and in 2013, he was awarded the National Museum of Mathamatics’ Rosenthal Prize for innovation in math teaching. On the left is Dr. Dan Fishman, a high school math teacher, who, like Brent, has unbridled enthusiasm for all things math.

Together, Brent and Dan staffed the “Ask the Mathamagician” table. Kids could walk up and ask them any question they could possibly think of involving math. We had prompt cards on the table to get things started:

Why do you like math?
What’s an irrational number?
What’s the biggest number there is?
Why is math important?
Why does a negative times a negative equal a positive?
Is zero a number?
What’s a perfect number?
What’s that crazy math thing with the exclamation point?
What’s an imaginary number?
Know any good math jokes?
What’s your favorite equation?

Brent and Dan brought a whole bunch of math toys and puzzles with them. It was an irresistible treasure trove of numerical goodies.

mathamagician 2Also at the Mathamagican’s table were three Digitopolis “tourism” posters for families to take home (the posters were inspired by this fantastic NASA concept). The first two posters are by Princeton University senior, Aliisa Lee. The third poster is by freshman Demi Zhang.

city poster by aliisa leemines poster by aliisa leeevent poster by demi zhangA quick word about the Mathamagician’s costume. The robes and hat were made by freshman James Jared, who ingeniously modified this Jedi robe. Then Casandra used silver and gold metallic fabric markers to draw real, honest-to-goodness math equations on them. We snapped a couple shots so you can get the full effect!

robes 2robes 1The Mathamagician wasn’t the only celebrity in Digitopolis that day. Does this gentleman look familiar to you?

albert einsteinYup, it’s Albert Einstein. Or rather, professional reenactor Bill Agress playing Albert Einstein. Mr. Einstein circulated the event floor, chatted with kids, answered questions about his life and work, tried an activity or two, and posed for pictures. And yes – he wasn’t wearing any socks.

In addition to being one of world’s most famous theoretical physicists (and no slouch at mathematics either), did you know that Einstein was a resident of Princeton? He emigrated here in 1933 to join the faculty of at the newly-created Institute for Advanced Study.

The Historical Society of Princeton put together a terrific mini-exhibit on Einstein in Princeton (my favorite is that photo of him wearing the fuzzy slippers). Families were invited to take home a map of notable Einstein haunts around town as well.

historical societyThey also whipped up an Einstein quiz for kids to try (the answers, by the way are B, A, B, C, B, C). The prize was a cool little puzzle. I found some terrific ones at Oriental Trading Company (the ones below are from the “Mind Teaser Game Assortment”).

maze prizesElsewhere in Digitopolis, another math wizard was hard at work. This is Emile Oshima, a junior at Princeton and master of the Japanese abacus. Next to him is senior Rei Mastsuura.

abacus races 1In addition to having Emile and Rei teaching kids how to use an abacus, Emile raced kids (and parents!) armed with electronic calculators to see who could reach the product of 3 x 3 multiplication problems faster. Emile always won. He was lightning fast!

abacus races 2Meanwhile, at another event table, another calculator was keeping kids busy. But this calculator was rather…odd.

crazy calculator 1The “Crazy Calculator” was designed by the Princeton Society of Women Engineers using 2 Makey Makey sets. Have you seen Makey Makey? It’s pretty awesome. Each set consists of wired alligator clips, a small central board, and computer software.

Attach the alligator clip to anything that conducts electricity, and you can do all sorts of crazy things. Turn bananas into a keyboard, or use Play-doe like a video game controller. The Women Engineers used all sorts of things to build their calculator – tin foil, wet sponges, water, metal objects, shaving cream, flowers, even high fives!

crazy calculator 2Interspersed with the other event tables were five “Pop Up History” activities that tied together math and history. These tables were designed to be simple, stand-alone, and un-staffed.

global counting 1At “Global Counting,” kids could see diverse numerical systems on a big display board (the book Go Figure: A Totally Cool Book About Numbers (DK, 2005) was very helpful in this regard). Then, kids copied their favorite number system on a 3.5″ x 17″ strip of paper, and used yarn to turn it into a little scroll.

global counting 2At another table were Möbius strips, a must-have for any hands-on math event. Discovered in 1858 by German mathematician August Ferdinand Möbius, the strip demonstrates how a piece of paper can have only one side! All it takes is a 2.5″ x 28″ piece of poster board, tape, and some instructions.

mobius stripsAnother hands-on math must-have? Tangram puzzles. Originating in China, tangram puzzles were first introduced to Europe in the 19th century. There are plenty of inexpensive tabletop tangrams out there, but we decided to splurge on some giant foam floor size versions (thinner ones purchased from SimplyFun, chunkier ones from Fat Brain Toys). Later, these were donated to a local non-profit family shelter.

tangram puzzlesThe fourth Pop Up History table was called “Tally Hides.” Some American Indian tribes kept track of important things by making tally marks on animal hides and tree bark. Definitely a cool way to count!

tally hides 1Before the event, we cut 9″ x 12″ pieces of brown paper into the shape of a hide. During the event, kids wrinkled the paper, flattened it out, and used markers to draw the wildlife they’ve seen around their homes and town. Then, they estimated how many times they’d seen each critter, and made a tally mark next to it. The project is originally from The Secret Life of Math (Williamson Books, 2005).

tally hides 2The final history table was called “Tile Tessellations.” Decorating surfaces with tiles spans many cultures, and many centuries. But did you know that the geometry in Early Islamic art was so intricate, it was unrivaled for over 500 years?

tiles 1Kids put their tiling and tessellating skills to work by gluing 3/4″ paper tiles to a 6″ x 6″ square of tagboard. This project was really bright and beautiful.

tiles 2That’s it for history – how about some games? JaZams, our local family-owned toy store hosted a event area called “The Game is Afoot.” JaZams chose 8 math games for various age ranges, and set each of them up on a series of tables. Kids could drop by to play the waaaaay popular Rubik’s Race…

game is afoot 1Or entire families could take a break and play Number Ninjas.

game is afoot 2Heck, maybe you could even beat Einstein at Qbitz! After the event, the games were donated to a local non-profit family shelter.

games is afoot 3For the musically adventurous, there was “Musical Fractions,” an activity composed by senior Matt Smith and freshman Demi Zhang. Kids used percussion instruments (assorted floor drums, wood blocks, maracas, a wooden fish, claves, and sand blocks) to learn how to play, and recognize, wholes, halves, quarters, and eighths. They also learned about musical structure and patterns.

musical fractionsEach instructional session ranged between 10 to 15 minutes. I wasn’t able to catch an entire one, but I did manage to grab a few seconds of this one. Just listen to those fractions!


I have one last thing to share with you. Team Digitopolis in their awesome event t-shirts.

front of shirtsAt big events like this, my staff and I wear costumes so that people can find us quickly in the crowds (helloooo Victorian Steampunk spelunker). For Digitopolis, however, I decided to go with t-shirts, and asked student artist Aliisa Lee to design them. Here’s a closer look at her beautiful cityscape!

digitopolis by aliisa leeOn the backs were our favorite numbers. Let’s hear it for 9, 2, and 11! Woot woot!

back of shirtsI’d like to send a million, trillion, zillion, googolplex thanks to everyone who made this event possible, and who generously gave their time to make math fun, approachable, unusual and fun. An extra shout out to the Princeton University students, and the student athletes who volunteered so energetically and enthusiastically! Thank you so much, everyone!
