Sneaky Math

sneaky mathWant a side of math with that story time? From simple to semi-sophisticated, here are some ways I’ve worked math into my library programs!

COUNTING SUPPLIES

There are multiple steps in my story time projects, and some of those steps involve selecting certain amounts of art supplies. So we’ll count together. For example, if the kids need 2 pipe cleaners for their project, I’ll hold out a bunch of pipe cleaners and count aloud as each kids selects them, “One…two! Great!”

NUMBERED SUPPLY CONTAINERS

During projects, I’ll often put  a line of supplies on the windowsill, and kids walk down the line and select certain amounts of supplies from each container. I used to use post it notes to mark the number needed on each container….

Sometimes, I’ll have a project that requires a diagram to demonstrates how much of something is needed. For example, this rainbow cloud project needed to be covered in cotton balls, so I drew a diagram showing how many balls needed to be attached, and how many cotton balls you’d need in total. Numbers, beautiful numbers.

I’ve also been known to sneak math into story time projects, like this lemonade stand that involves counting, sorting, and sequential thinking.

Now who’s up for something a little more…elaborate?

In 2012, my library hosted a large-scale Robin Hood event. I knew we just had to do something on taxes. But how were we going to design something that involved taxes, math, Medieval history, but was also simple enough for kids of various ages to grasp quickly? The answer came from my brilliant event assistant Katie. We would design a tax wheel game based on Hi Ho Cherry-O.  We called it “Your Tax Dollars at Work.”

tax wheelHi Ho Cherry-O is a classic early math game involving counting and numbers. The game is driven by a spinner that dictates whether you add or remove cherries from your basket during game play. But what if the spinner for our version pointed to various Medieval taxes, the game pieces were coins? We could even throw some Robin Hood characters on the wheel. Perfect.

We knew needed to go big and durable at such a large, crowded event. So I ordered a 36″ blank roulette wheel from Spinning Designs Incorporated. The company was very tickled by the novel use of the wheel. Perhaps that’s why they gave me a fantastic (and much appreciated) deal on a wheel that had “minor surface imperfections” (which I honestly could never find).

Then Katie and I researched the different types of taxes from Robin Hood’s day. There were a lot (honestly, who taxes you for churning your butter?). We also had to find a way to gain coins back during the game.

Ultimately, we came up with the following “Lose” and “Gain” categories.

Lose Coin

  • Travel tax
  • Churn your butter tax
  • Bake your bread tax
  • Pay your lord
  • Grind your grain tax
  • Sheriff steals
  • Prince John takes all
  • Land tax

Gain (or at least not lose) Coin

  • Harvest time
  • May Day
  • Good day at market
  • Robin Hood gives you coins

As you can see, there were more ways to lose your money than gain it. We intentionally designed the game that way. There were going to be so many people at the event (3,500 actually) we wanted the game play to average 3 minutes so lots of kids could have multiple turns. If you’re interested, here are the complete game instructions.

game boardsWhen all your coins were gone, the game was over! As a “consolation” prize, kids got a chocolate foil-wrapped coin. Kids with food allergies or dietary restrictions got to take home one of the metal replica coins.

The “Your Tax Dollars at Work” wheel and game boards were drawn by Kemi Lin, an amazing Princeton University student artist. She did it all. By hand. With packs of Sharpies. After the event, the game was donated to the Somerset County library system. Long may it live!

The Perfect Boggart

the perfect boggartNeed a boggart in a suitcase to transport to your next Defense Against the Dark Arts class? We can make that happen! Imagine a suitcase innocently resting on a tabletop (or handsome leather chair). But then, just when you least expect it, it jumps and bumps as the boggart inside tries to escape!

I created this suitcase boggart for a Harry Potter event my library hosted, and it was very much enjoyed. Best of all, it was super simple to make. The secret behind the boggart is this:

weazel ballMeet the “Weazel Ball.” It’s a pet toy with a rotating motor inside it that causes the ball to scoot around randomly, pulling and twitching the furry weasel on top. It’s meant to drive cats and small dogs crazy, but I knew it would be the perfect boggart. I purchased this one on Amazon for $6.

In addition to the Weazel Ball, you’ll need a suitcase or trunk. The 12″ X 18″ suitcase pictured in this post is made of decorative cardboard. I found it at Michael’s Crafts on the 40% discount shelf, so it cost $15. Woot woot!

My suitcase was smooth on the inside, but if you use something with a textured wood interior, you might consider removing the furry weasel from the ball so it doesn’t snag on the wood and slow the ball down.

interiorThe most important thing when selecting your suitcase (or trunk) is the ability to latch or padlock it shut. This will prevent young skeptics from pulling up the lid and shouting “Daaaaad! I told you there’s no boggart in here!”

latchesThe other thing you’ll need are spare batteries. If you haven’t heard from your boggart in a while, the battery may have run out (the Weazel Ball uses a single AA). Depending on how long the event is, you’ll want several on hand.

You could get ambitious and put more than one Weazel Ball in the suitcase (I’ve only tried one). But if the suitcase is threatening to bounce off the table, put some no-skid rug runners or self-adhesive foam pieces on the bottom to help it stay in place.

Worth the Splurge III

box portraitI use a fair amount of boxes for my projects, and what wonderful boxes they are!

While said projects can be done with tissue or household boxes, I admittedly splurge on these 100% recycled gift boxes from Nashville Wraps (the “economy matte white” ones are shown above). Why? Oh, let me count the ways:

  1. They’re packed flat, which makes them super easy to store (and since my storage is limited, this is a huge plus).
  2. They offer a blank template to begin with (instead of having to cover a tissue box with white paper, for example).
  3. They hold up really well to marker, crayon, tape, white glue, glue sticks, and hot glue.
  4. These dandy boxes also come in brown, which I’ve used to make this adorable little produce stand, this fantastic boat hat, this splendid garden, this candy factory, this bouncy bed, and this creepy carrot basket.
  5. They’re 100% recycled! And I love me some recycling.

So, how much of a splurge are these boxes? Well, if you want to buy a case of the white 4 ½” X 4 ½” x 9” size (which I use pretty often – see this monster feet project, this dog project, this ice cream truck, this robot marionette, and this dragon), you can buy a case of 100 for $26.50. That’s 27 cents a box. Pretty good!

They come in different sizes of course. I used a white 4″ x 4″ x 4″ box for this dentist project, this hot air balloon project, and this floating island. You can buy a case of 100 for $15.90 or, 16 cents a box.

Shipping can add some cost. The good news, however, is that Nashville Wraps offers flat rate or free shipping (plus a small handling fee) when your order reaches certain levels. I take advantage of this by estimating what I need for a year and placing one BIG order to get a break on shipping. The cases of boxes easily stack in a closet or under a table. Nice!
