Do you have some restless rovers in the house? How about sending them out to build and navigate a custom labyrinth or maze…for less then five dollars! This idea came courtesy of the Princeton Buddist Meditation Group, which hosts this little labyrinth in the community space behind their center.
You’ll need:
- Open space
- Rocks
For starters, you need a bit of open space. Any patio, porch, driveway, or sidewalk will do. If you’re in an apartment, you can always clear a room or build a tabletop version.The only other thing you need? Rocks! Bags of these are available at home improvement stores and garden centers. A 0.4cu foot bag of white rocks at Lowe’s, for example, is just $3.98.
To create the labyrinth, simply line the rocks up to form the walls of your winding path, and off you go! If you don’t want to create your own design, there are plenty of labyrinth templates available online for you to replicate.
What’s the difference between a labyrinth and a maze? A labyrinth is a single winding path that ends in the center of the creation. The focus is on the journey. In a maze, the path has choices, dead ends, and may or may not end in the center. The focus is on entering and exiting.
This rock labyrinth can certainly be modified to become a maze. The beauty of using rocks is that you can switch things up at anytime! And if you’d like a slightly crazier maze challenge, why not try our “No Right Turn” maze here?
This intrepid bear marionette marches over all obstacles in our library landscape… searching for new friends and a cozy place to call home!
This marionette is designed with simplicity in mind! First, cut the bottom off a small box.Then cut the box down to about 2.25″ tall. Punch two holes in the top of the box, and thread a 29″ piece of string up and out of both holes like so:
Tie the free ends of the string to a wooden dowel rod. If the top of your box has a lid like ours did, make sure to tape it down tightly.
To make the bear’s legs, cut 2 toilet paper tubes in half. Punch 2 holes in the top of a half, then thread a 10″ piece of string through the holes like this:
Repeat the above steps with the remaining three legs, then tape all 4 legs to the inside “ceiling” of the box. Here’s a shot of the underside of the box with the leg strings taped in place.
Did you notice the black button in the image above? We hot glued that to the inside rear of the bear to counterbalance the button on the bear’s snout. It helps keep the marionette from leaning forward too much.
When the bear marionettes were finished, we encouraged kids to pull books off the shelves and use them to create mountains, walls, ramps, bridges, and paths for their bears to travel across. A few kids also made cozy little places for the bear to nap. Awwwww!
As you can see, we had a paper bowl tunnel, a bumpy drinking straw “path,” green pipe cleaners acting as vine wickets, and a blue construction paper river. We used tagboard to make a bridge, as well as a ramp and an elevated pathway. At the bottom of the box lid are the “goals”…paper cup halves cut down to various heights. Want to fill things out a little? Add construction paper foliage:
You can also add fabric (or construction paper) flowers for some pops of color!
To play, drop a bouncy ball in anywhere, then navigate through the obstacles and foliage by tilting and turning your box top. The ball goes in a cup, you win! Bonus fun – use multiple balls at once, or play with one kid at each end of the box top!
We’ve all wanted to jump into books. Who doesn’t, for example, want to go to Diagon Alley and hit the shops? Join Hazel for stories in the Honeycomb? Explore Babilonium with Candy Quackenbush? Or sail the skies with Matt Cruise on the Aurora? Part of my job at the 
But before I get started on all the details, I’d like to introduce our event collaborator, 
Bedtime Math brought 3 fantastic activities to the event: Spy Training, Beach Ball Party, and Glow-in-the-Dark Geometry. Here’s Spy Training, which was all about codes and ciphers…
And here’s Beach Ball Party, which involved counting, stacking, and chasing beach balls determined to make a break for it.
It also involved Ellen Williams (who you last spotted being pelted with marshmallows in 
Some kids decided to use the original plastic connectors that came with the bracelets to make unique geometric creations. Here’s one of my favorites. A series of loops that, when spun, becomes a sphere!
The mines were stocked with an assortment of wooden numbers. I used 4″ numbers I found online at Woodcrafter. If you’d like a cheaper option, I recommend printing paper numbers on card stock.
The mines were staffed by high school volunteers from the Arts Council, who were suitably decked out in miner helmets.
Elsewhere in Digitopolis was the “Fibonacci Forest,” hosted by the 
The Watershed also did a cool fractal tree project. It involved a half-sheet of green paper, brown markers, and rulers (here are the 
We decorated the finished fractal trees with bird and leaf stamps, but you can also just use markers or color pencils.
And speaking of wildlife, how about some zebra math? We were delighted to be joined by Princeton University Professor 
Some researchers believe that zebra stripes exist to confuse predators. So Dan and his constituents developed “Dazzle Confusion,” an iPad game in which kids “become the lion” and tried to tap black, white, or striped moving targets to determine which one is most difficult to hit.
At the end of the game, the program tabulated the kids’ results and displayed them on a large screen. As the event progressed, the results continued to accrue. This lead to conversations about data collection, measurement, central tendencies, and averages.
It’s worth noting that although there was much variation on kids’ “strikes” on the targets, there was a strong trend (p < .08) showing that the striped targets were hardest to hit! How’s that for some real world math?
Here’s a screen shot of the game, which was created by sophmore Lucy Lin. If you’d like to test drive the game yourself, here’s the 
The game was cool, but even cooler was the fact that there was another laptop running tandem to the gaming laptops that showed all the algorithms behind the Scratch program. And volunteers were on hand to answer any and all questions about computing. They also had a couple of encryption puzzles for kids to crack.
For those who prefer their math undiluted, the Princeton University Mathematics Club came out en force to host a “Playful Problems” table. Here, kids found a plethora of logic puzzles, word problems, visual puzzles, calculator tricks, the works!
There were 12 different activities for children ages 4-10. The activities ranged from easy to moderately difficult. Here’s an example of our simplest puzzle, which was created by Casandra Monroe (whom you first met 
Below is a list of what we offered at the event table. In addition to using Google to find some of these puzzles, Math Wizardry for Kids (Barron’s, 1995) and How to be a Math Genius (DK Children, 2012) were terrific resources.
By the way, did you notice the cute play cart parked in the upper right corner of the above image? That’s one of our “Trio of Treats.”
I always try to include something for the littlest patrons, so I bought 3 adorable food carts and stocked them with math play sets. The food carts are by KidKraft (Sweet & Sunny Lemonade Stand) and the play sets are by Learning Resources. We used Piece-A-Pizza Fractions, Number Pops, and Count ‘Em Up Popcorn.
One of the most popular event tables, however, was “Visit the 4th Dimension.” It was hosted by 
At the event table, kids learned about the different dimensions (1st is a line, 2nd is a square, 3rd is a cube, 4th is a tesseract). ScienceSeeds brought their 3D printers to the event and made models. You can see a tesseract in progress below. Awesome.
Kids could also make 3D models of their own using drinking straws and plastic connectors. You can buy the plastic connectors online (from Strawbees). However, scienceSeeds has a die cut machine and was able to purchase the die cuts (from Accucut) and make their own connectors from plastic sheets (from Grafix).
Like I said, their table was hopping – they estimate they went through at least 3,500 straws!
The thing I liked most about the project is that there was no limit to the shape, size, or intended use of the 3D models.
