Pumpkin Seed Math Games

Kathy J. —  October 20, 2014 — Leave a comment

If you carve a pumpkin for Halloween or make pumpkin pie from scratch, you’re going to have a lot of pumpkin seeds. You can put them to good use by turning them into “dice” and playing math games this fall.

First, you’ll need to remove, clean, and dry the seeds. After scooping the pulp from your pumpkin, place it in a bowl of water and gently rub the stringy pulp off the seeds. Rinse them in a colander and let them drain. Prepare a baking sheet with a layer of parchment paper. Do not add any oil. Spread seeds in a single layer on the paper. Bake in an oven preheated to 300 degrees Fahrenheit for 30-40 minutes to dry them. Store them in a plastic bag or airtight container.

These seeds were baked for just over 30 minutes at 300 degrees. After they have cooled, they will be ready to become instruments of learning.

The kind of dice you make will depend on the game you want to play, but for all games the basic idea is the same. Players will toss the seeds and the side that lands face up is the number they will work with. You’ll want to select seeds that are more flat than rounded. Remove any transparent skin that remains on the seeds, so it won’t dissolve in the marker ink and make a mess. Use a regular fine Sharpie or other permanent marker. I find that the extra fine markers tend to dry out while writing on the seed. You can use any color, but for some games the color matters. You’ll also want to establish a top and bottom of the seed. I write all the numbers with the point of the seed on the bottom so 6s and 9s don’t get confused. 

Here are some games you can make:

To make a game of “Count the Dots,” draw dots on one side of each seed as shown.

Count the Dots

This works well for young children learning to count. Take six pumpkin seeds. On one side of each seed draw dots like those on a die. Leave the other side blank. To play, toss the seeds and let them land. Count all the dots facing up. The person with the most dots wins!

Add the Numbers

Older children who are learning to add can play with numbers instead of dots. You can vary this depending on the skills of the children. For early learners, make two each of 1, 2, and 3. For children practicing higher number adding, make a range from 1 to 9. To practice adding higher numbers, make a set with all 6s, 7s, 8s, and 9s. Those are scary numbers to add until you get the hang of it, which is the whole point of this game.

To play, toss the seeds, then move the blanks out of the way. Line up the numbers so they are easier to see and add up.

Addition and Subtraction

Working on subtraction? Write the number on one side of the seed in black and write the same number on the opposite side in a different color such as red. Now when you toss the seeds, add all the black numbers and subtract the red numbers. The result could be a negative number!

Playing with addition-subtraction rules where black numbers are added and red numbers are subtracted, this toss would be 1 – 7 – 2 + 4 + 8 – 6 – 9 + 3 + 5 = -3.

Evens/odds

This game works with dots or numbers, but requires a set with writing on one side only. Players take turns predicting the outcome of the toss adding up to an odd or even number. The first player calls “odds” or “evens,” tosses, checks the results. S/he gets a point if s/he is right, a point goes to his or her opponent if s/he guessed wrong. 

Numbers and Symbols

You can have more than numbers on your dice. Make a set of seeds that include numbers and function symbols: + , -, ×, and ÷. Each player should have her own identical set of seed dice. All players toss at the same time and the person who can make the number sequence with the highest answer wins. In this game, players are allowed to combine numbers to make a larger number. For example, a 1 and a 2 can become 21, as long as all the exposed numbers and symbols are used. The simplest rules for this game will be to take the order of operations from left to right, but players who want to stick to the “PEMDAS” order of operations (parentheses, exponents, multiplication, division, addition, subtraction), can certainly work that into the game.

Working with numbers and symbols gives a score of 413 for this toss.

Matching Equations

To make the game more cooperative, play the same game above, only this time the two players try to make their two number statements equal each other, or get as close as possible. This is more difficult to accomplish. so it’s all right to be a little flexible with the rules, since the players are not competing and you won’t have to settle disputes.

Players can make up their own games. They can also work in more complicated operations like exponents, or they can arrange the placement seeds above and below a line to represent division (this may require paper and pencil). Chances are, if they have reached this level of sophistication with mathematical operations, they would prefer eating the seeds to playing with them, but it’s still a fun challenge.

Whatever their level, when players have exhausted their interest in the seeds, be sure to take a break and enjoy some pumpkin “pi.” Sorry, I had to include that, because let’s face it, if you’re playing math games for fun, you’re a person who appreciates this humor!

Are your summer or early fall container gardens looking tired? Change out your container gardens to extend your displays well into the fall.

Gardening in containers can offer us year-round seasonal interest, and we can extend the garden seasons to create vibrant container gardens. I’m a huge fan of fall container gardens with a rich variety of color, texture, and hardiness that carry their beauty well beyond the first frost. 

A container garden that changes its appearance from one season to another is the definition of a seasonal “change-out” concept. Change-outs can be done by simply removing or adding one or more plants, objects, or other material to the container to add seasonal interest. Color alone can offer more impact on the container garden than any other design element. (However, nothing has more negative impact on the container garden than a poorly maintained appearance or bloomed-out flowers.)

Change-outs should take advantage of seasonal blooming plants and colorful foliage and textures in prime condition. The change-out can add instant color or texture to the display and create a “wow” from one season to another. Color schemes can change through the seasons as well, such as pastels and soft tones in the spring, bright and colorful combinations in the summer, warm and autumn-like colors in the fall, to greens and interesting textures in the winter. Your container gardens can change and develop through the year much like a garden bed or border do in the landscape.

While chrysanthemums still reign supreme in many gardens and containers every fall, try other interesting plants such as asters, ornamental or flowering kale and cabbage, heuchera, pansies and violas, and ornamental grasses. These plants all are cold hardy, and will tolerate light frosts, lasting well through the autumn season.

I love the combination of using purple or blue asters with ornamental kale—the colors play off each other nicely in a long-lasting display. Using other lesser-known plants—such as some of the fall-blooming salvias—can add height and create interesting combinations in your container gardens. Cold-hardy vegetables and herbs can also be added for interest and texture. I like using swiss chard, broccoli, Asian greens, parsley, and alliums to add interesting and colorful effects to my containers.

Another thing I like to do when creating fall displays in containers is to incorporate pumpkins, gourds, dried corn, branches and leaves of trees or shrubs, and autumn or Halloween decorations. A fun and simple addition to your fall containers may be to simply carve out a large pumpkin and use the pumpkin as a container, placing a combination of fall plants in it to decorate your front door or patio.

Fall on the Prairie

Carol Freeman —  October 15, 2014 — 2 Comments

While summer blooms elsewhere are winding down, the Dixon Prairie is still alive with many fall flowers.

Asters, sawtooth sunflowers, gaura, and goldenrod are going strong. All of them are abuzz with bees and other insects. Grasshoppers dance from plant to plant. Butterflies fuel up for a last fling or long journey.

Grasses, some with tiny fragrant flowers, sway gracefully; many have grown more than 7 feet tall in this one growing season. Early morning dew transforms the seedheads into works of art. Silken strands of unseen spiders glow in the sunlight. Flocks of goldfinches munch on seeds, stocking up for winter, chirping their happy tunes, while shy sparrows occasionally pop up from the shadows, giving us a glimpse of their subtle beauty. Milkweed seeds blow gracefully in the wind.

The prairie truly must be walked to be appreciated. There is so much diversity, and so many stories to tell.

Touch a compass plant leaf on even the hottest day and it will be cool to the touch—with roots going down 14 feet, they pull up water that is chilled underground.

Monarchs live in symbiosis with milkweed plants (as do many other insects). Look closely and you may see a whole world on a milkweed plant.

Surprises can be anywhere—a hummingbird zipping by for a quick sip, a great blue heron flying overhead, drama as a hawk dives down to grab a vole. Fall on the prairie is colorful, alive, and a place of great wonder not to be missed.

Adriana’s Bird of the Day is the Kingfisher

Or, everything I needed to know about birding I learned at the Garden

Adriana Reyneri —  October 13, 2014 — 1 Comment

A partial transcript of my first official bird walk:

Me: What was that call?

Expert birder: A chipmunk.

Me: What’s that big brown thing in the branches? It’s shaped kinda like a hawk.

Expert: Dead leaves. We call that a fake-out.

Me: Right.

Expert: Do you hear that rattle? I hear a kingfisher!

I really do not hear the rattle, but I feel a rush of excitement as I chase my guide along the trail of the Barbara Brown Nature Reserve at the southeast corner of the Chicago Botanic Garden. The tree-lined pond is one of many different habitats that make the Garden an excellent place for birders experienced and otherwise. Adding to my great fortune are golden sunshine—lighting the first red, orange, and yellow leaves of autumn—and the presence of Al Stokie, who comes to the Garden every week to report on shorebirds and other avian visitors. I’m tagging along on one of his early morning surveys and gleaning basic principles of birding.

Several area bird clubs—including the Lake County Audubon Society (an Illinois Chapter of the National Audubon Society) and the Evanston North Shore Bird Club—welcome beginning birders to their regular meetings and field trips.

Al Stokie comes to the Garden weekly to monitor bird populations. He files his counts on the IBET website.

It’s seasonal

Our first stop was the expansive deck of the Kleinman Family Cove, one of Al’s favorite spots for viewing the North Lake. In just a few weeks the surface would be filling with ducks stopping to rest on their way south for the winter. They’ll be followed in November by grebes and red-breasted mergansers. Native plants surrounding the cove attract a variety of birds, but most of the tiny warblers left for warmer climes weeks ago. McDonald Woods, a restored native oak woodland, is the place to go in the spring to catch the warblers’ return and, if you’ve got really good eyes, a place to spot owls in the winter.

“It’s all seasonal,” says Stokie. “Every month of the year you can go out and see different things.” I like that idea: The Garden as an ever-changing landscape of birds.

It’s all about the food

We continue along the North Lake road and find two more potential hot spots for birds. A peninsula of land supports a grove of evergreens loaded with cones—a big draw for wintering pine siskins and—if you’re lucky—crossbills. Down the road a bit, you come to an Emergency Call Box. Look past it and you’ll see large junipers growing along the exterior wall near the Garden’s northwest corner. That’s where a very rare Bohemian waxwing, feasting on the juniper berries, was last seen in the Garden.

Walk early, and walk often

We are heading south now, along the Garden’s West Road, past a restored streambed, lush with native plants—a habitat that provides lots of seeds and insects. The best time for birding tends to be the four hours or so following sunrise, so getting up early can have its rewards. Persistence also pays off, Al explains: “It’s a matter of odds. If you look in one spot ten times, you’ll probably see something.” Just then we catch sight of movement in the shrubs. Al first identifies the little bird by the way it waves its tail up and down—an (ahem) telltale sign of the palm warbler, one of the last warblers to head south for the winter.

The Joseph Regenstein, Jr. School of the Chicago Botanic Garden also offers guided bird walks. Learn more about bird walks taking place at the Garden this fall.

Seedheads from native plantings along the restored Skokie River corridor provide ample food for birds.

It ain’t easy—even for the experts

Flocks of goldfinches—displaying olive drab winter plumage—are diving in and out of the tall forbs and grasses of the Dixon Prairie. Niche ecosystems within the prairie provide food and shelter for many different types of birds at different times of the year. Hummingbirds are drawn to the red blooms of royal catchfly (Silene regia) that flower on the dry gravel hills in the summer, while the prairie wetlands attract swamp and other types of sparrows. Turns out sparrows can be tricky to identify, unless—as it happened—one stops to feed on the path in front of you. Al identifies it as a white-crowned sparrow. “For every bird you identify, there are probably five or six you do not get a look at—or you get a lousy look and don’t know what it is,” Al Stokie.

Watch the weather

Shorebirds are drawn to the southwest corner of the Garden, an overflow area for the Skokie River with plenty of muddy shores. “Old Faithful,” a white egret nicknamed by Stokie, comes in for a landing, joining a well-camouflaged green heron and a killdeer, the hardiest of the shorebirds and a late migrator. Most of the sandpipers—Al’s particular interest—have left already. In a flash of movement, the heron fishes a frog out of the water. We witness its slow death through our binoculars, though I have to admit I am still struggling to focus and aim mine. Standing on the sunny, breezy path it’s hard to believe a cold front will be moving through in a few days. That’s likely to bring in a new wave of migratory birds, in this case, sparrows.

Find a mentor

A beginning birder who comes out on his own with a bird book and a pair of binoculars is likely to be overwhelmed, Stokie said. This makes perfect sense to me. Without Al at my side, so much of the experience would have…er…flown right over my head. Take that belted kingfisher back at the Barbara Brown Nature Reserve. While I was still craning around, listening for the rattle, Al had sighted the bird perched in dead branches across the pond. Handing me his binoculars, he asked, “Do you see something, blue?” I saw flashes of blue and white, and the shape of a stocky bird, with a big head.” Okay, it was still slightly blurry, and I had to close one eye to make it out, but I saw it! The moment was recorded for posterity when Al filed his count online. I felt a ridiculous burst of pride when I read the mention, “Adriana’s bird of the day is the kingfisher.”

Join us from 7 to 9 p.m. Friday, November 14, for an Owl Prowl at Ryerson Woods. Click here to register online.

Experienced birders David Johnson, Jeffrey Sanders, and Alan Anderson, as well as Jim Steffen, the Garden’s senior ecologist, also helped me gather information for this report. To follow sightings by Al and other local birders, you can go to several websites, including eBird (ebird.org/ebird/places), which designates the Garden as a hot spot, and IBET (groups.yahoo.com/neo/groups/ILbirds/info).
