Exploring Bridges with the Three Billy Goats Gruff

IMG_8484(2)We began with The Three Billy Goats Gruff, illustrated by Janet Stevens.  Check out the eldest of the Gruff brothers, one of the hippest, toughest brothers I’ve seen in a picture book!

IMG_8487We tapped the “trip-trap” sound of the goats hooves on the bridge, getting louder as the brothers grow in size, finally hitting the floor to make the loudest “trip-trap” sounds with the biggest brother. The children enjoyed repeating the sounds when we acted the story out after reading the book.

Next I read part of Ken Robbins Bridges (Dial, 1991), a lovely nonfiction picture book with evocative hand-colored photographs and short and very informative explanations for why bridges are built different ways. The book includes London’s famous Tower Bridge, which features a drawbridge (bascule) that goves up to allow boats to pass underneath.  We watched a simple animation of a drawbridge, and then built our own drawbridges out of cereal boxes. It is a fairly simple project, but cutting cardboard, punching holes, and measuring the yarn required adult assistance.

It was great to see the interactions taking place — lots of scaffolding here, with parents guiding little hands to thread the yarn through, having them help measure the length, etc. And when it’s over, pull the yarn to lift the bridge and put it over your shoulder to carry home. One child used his portable bridge to carry a library book safely home!

Would you like to live in a treehouse?

At the Books & Blocks program at Westerville Library, we explored treehouses.

jackjilltreehouseWe read Jack and Jill’s Treehouse by Pamela Duncan Edwards (HarperCollins, 2008), which is written in a cumulative “house that Jack built” style.

Then we read part of Adventure Homes by Gerry Bailey (Crabtree, 2013) which has a great outline of the structure of a treehouse, and includes information and photographs of the Korawai and Kombai people of Papua New Guinea, who are known as “the tree people” because they build their houses high in the forest trees.

Afterwards, the children built with a variety of materials: wooden blocks, legos, magnetic blocks and large cardboard bricks.

They also used ramps and balls, envisioning having slides to descend from the treehouse.

Books & Blocks: Castles

The Books & Blocks program at Westerville Public Library is fun, simple, and engaging. We start by reading a book or two, singing a song and moving around, and then build! With wooden blocks, legos, or other materials. Last week we explored castles (though children are free to build anything they want.)

Book: Mr. King’s Castle by Geneviève Côté

Book: Castle: How it Works by David Macaulay

Song: “Up Goes the Castle”, from Sesame Street

In the photos below, you can see one child building a castle with an outer wall, central keep, and four watchtowers, just as Macaulay describes in Castle.

“Up Goes the Castle” is a wonderful, quiet (and silly) song where the castle is on your stomach! The children are lying down with their hands making the castle on their stomach — as the breath out, the castle goes down; breathe in, the castle goes up. Great for a program like yoga tales as well. I was delighted at how well a quiet song worked in a preschool storytime.

Exploring Rocks

I opened storytime with Peggy Christiansen’s poetic If You Find a Rock,  in which she describes all kinds of rocks a child might find: skipping rocks, climbing rocks, worry stones, splashing rocks, memory rocks and more.

if you find a rock

 

Next we played the stepping stones game. I had cut out rounded shapes from construction paper and taped them to the floor in groups of three before the program began. I had the children line up behind a set of stones (I had four sets, and four to five children in each group, so no one had to wait to long.) Then they stepped across the pretend river using the stepping stones. I introduced this rhyme, and we did it over and over and over again, until they all could say it with me and had crossed multiple times.

Stepping Stones

Stepping over stepping stones,
One, two, three.
Stepping over stepping stones,
Come with me.
The river’s very fast,
And the river’s very wide,
We’ll step across on stepping stones,
And reach the other side.

Next I shared If Rocks Could Sing: a discovered alphabet by Leslie McGuirk. They loved hearing about how she found the rocks (lots of waiting!) and sometimes agreed (and sometimes disagreed!) with what shape she saw in the rocks — it was great for generating conversation.

ifrockscouldsing

 

We talked about looking for shapes or letters in rocks. I also showed them some of artist Andy Goldsworthy’s creations with rocks before we set out to make our own creations.

There are many more great rock books for this age, like Roma Gans If You Go Rock Collecting from the Let’s Read and Find Out Science series, and for a little older audience, Rocks in His Head by Carol Otis Hurst and A Rock is Lively by Dianna Hutts Aston.

Next we went outside to continue our rock explorations. We had talked about how rocks were hard . . . and soft (like chalk). One station was sidewalk chalk, another was painting rocks (what letter or shape do you see in this rock?), and a third was stacking or building with rocks. It was a beautiful day for the kids to explore!

The Three Little Pigs Variations

For our Books & Blocks program, we explored building with variations of the Three Little Pigs. I began by retelling the story of the Three Little Pigs with a magnet board, asking children to help me remember the story.  Along the way I asked them what kind of house did they live in — a straw house? no! a wood house? (a few yeses) a brick house? etc. Next I read The Three Little Pigs: an architectural tale by Steven Guarnaccia.

threepigsThen we acted out the story with Laurie Berkner’s “Lots of Little Pigs” song. I had used masking tape to make three squares on the floor to represent the pigs’ houses before storytime. Now I asked for volunteers to be pigs and pick a house, or to be a wolf and join me.

Then there was plenty of time for building their own houses . . . or whatever they wanted to create, with legos, wood blocks, or cardboard bricks.

There was also a cardboard house for them to re-enact the story, which many children did, taking turns looking out the window or knocking on the door pretending to be the wolf.

I’ve used other variations of the Three Little Pigs as well. For our Family Tales, I shared Claudia Rueda’s delightfully spare Huff & Puff

and Mark Teague’s potato chip and sody-pop version, The Three Little Pigs and the Somewhat Bad Wolf.

My all time favorite variation is Euguene Trivizas’ The Three Little Wolves and the Big Bad Pig with irresistible illustrations by Helen Oxenbury.

Sink or Float

Will it sink or will it float?  This was the question that we asked during our Wonderworks program this week.

We opened our program with the picture book Who Sank the Boat?, by Pamela Allen.  In this story, which continually asks the listener, “Do you know who sank the boat?,” a group of animal friends all take turns boarding a row boat until it is finally so heavy that it sinks.  Which of the friends finally sank the boat?  Our storytime participants all had a fun time guessing until the very end.

who sank the boat

After our picture book, we all pretended to board our own row boats and sang Row, Row, Row Your Boat, adding a variety of different verses.

SongRow, Row, Row Your Boat

Row, row, row your boat

Gently down the stream

Merrily, merrily, merrily, merrily

Life is but a dream.

Bump, bump, bump your boat….

Sway, sway, sway your boat…

Row, Row, Row your boat underneath the steam

Haha I fooled you

I’m a submarine!

For our non-fiction book, we used the book Will It Float or Sink?, by Melissa Stewart.  The text of this  book discusses many different objects that will sink or float in water and why this is so.  As we read, we demonstrated to our storytime participants how each object mentioned in the book either floated or sank in water, using a clear plastic tub.

???????????????????????????????

After our demonstration, it was time for the children to discover for themselves which objects would sink and which would float. We let them test out numerous items in our plastic tubs of water.

In addition to testing out which objects would sink or float in water, the children were given sheets of aluminum foil which they could use to fashion into small boats to float on the water.  They could then experiment to see how many pennies it would take to sink their boats.  Some of the children tried floating other items in their boats in addition to the pennies.

Our strongest boat held over 50 pennies!

Igloos

This past winter in Wonderworks, we decided it would be appropriate to do a theme on Igloos.

After opening with our Energy song, we asked the children what they knew about igloos.  We asked if they thought it would be easy or hard to make an igloo, if it would take a long time, where igloos were made.

We read the book Building an Igloo, by Ulli Stelzer and then showed them a brief YouTube video on the iPad of a man teaching his son how to make an igloo.

building igloo

When we’d finished reading the book and viewing the video, we asked the children the same questions that we had asked earlier to see if they had changed their opinions or learned anything new about the art of igloo building.

We then listened to and acted out the song, Let’s Play in the Snow, by Rachel Buchman. This is a wonderfully fun and imaginative (not to mention, silly) song about dressing up and going out to play in the snow.

Let’s Play in the Snow, by Rachel Buchman

Another good song/activity for this theme that we had in our plans but didn’t have time to do (but perhaps you might) is one that’s sung to the tune of All Around the Mulberry Bush.
Feel free to add as many verses as you’d like.

Song: This is the Way We Build an Igloo

This is the way we pack the snow

pack the snow, pack the snow,

this is the way we pack the snow,

when we build our igloo.

This is the way we cut the snow…

This is the way we lift the blocks…

This is the way we cut the door….

etc…

After our song, we read our picture book.  For this theme, we chose Jan Brett’s The Three Snow Bears, a version of Goldilocks and the Three Bears.  The children loved Brett’s retelling of the familiar story of The Three Bears set in a polar igloo.

Before moving on to our last activity, and because it’s one of the children’s favorites, we did Dr. Jean’s song, The Cool Bear Hunt.  This version of We’re Going on a Bear Hunt never fails to entertain our eager group.

For our activity, we constructed marshmallow igloos.  For this, we required a few bags of mini marshmallows, some tacky glue, some Styrofoam plates and some paper plates.  We passed out foam bowls (with openings that we had pre-cut) to the children upside down on paper plates with some tacky glue squirted on each child’s plate.  The children could then dip the marshmallows into the glue on their plate and add them to their bowls to make igloos. I am delighted to say each child completed his/her own igloo with little to no assistance whatsoever from accompanying adults.

Full STEAM Ahead!

Wonderworks is the Westerville Public Library’s STEAM (Science, Technology, Engineering, Art and Math) storytime for preschoolers. This week’s program featured tunnels, beginning with Ryan Ann Hunter’s Dig a Tunnel.

We introduced the idea of tunnels for transportation — tunnels that go through mountains or even under water. We talked about trains that go underground in big cities before watching the Tumblebook version of  Subway Ride by Heather Lynn Miller.

This colorful picture book features different underground trains from around the world: from the London Underground (the Tube!) to Stockholm’s T-bana. In the pages featuring the New York subway, the Tumblebook plays jazzy music referenced in the text.  You can play Tumblebooks at home, just visit the library website and have your library card handy.tunnel1

 

You can also explore tunnels with your child at home. Save cardboard tubes from paper towels or wrapping paper to use as tunnels for trains and cars. Or use them to make your own marble run. We attached velcro to toilet paper rolls to create a marble run on the activity center wall (thanks to the LibraryMakers site for the idea!). Children love to crawl through tunnels, so save your cardboard boxes to make long tunnels.

STEM Storytime: Building

This week’s preschool STEM (Science, Technology, Engineering and Math) Storytime focused on building. First I asked the children what materials they like use to build things. Blocks, legos, sticks, sand, and snow were mentioned. All of these, plus many more, can be found in Christy Hale’s Dreaming Up: A Celebration of Building (Lee & Low, 2012), which pairs illustrations of a child building with different materials with a corresponding work of architecture.dreaming up

 

Wooden blocks are juxtaposed with Frank Lloyd Wright’s Fallingwater. Sand castles are paired with Gaudi’s Sagrada Familia Cathedral in Barcelona. All the children nodded when I asked if they had a set of stacking rings when they were a baby.

 

After looking and talking about the book, children were given a variety of materials to construct their own edifices. And build they did!

Marshmallow Bridges and Building Fun!

STEM Storytime recently focused bridges, featuring Phil Bildner’s Twenty-One Elephants (Simon & Schuster, 2004)

which tells the story of the building of the Brooklyn Bridge from a little girl’s point of view. Her father, family . . . indeed, everyone she knows, feels the bridge is unsafe. That is, until master showman P.T. Barnum parades his 21 elephants across as testimony to its stability.

We then learned about different kinds of bridges, like-beam, arch, suspension, and truss, and talked about what shape is most stable (the triangle), before beginning to build with marshmallows and toothpicks.

 The materials are basic, but open the door to so many possibilities!

If you’re looking for an easy, open-ended activity for the kids, marshmallow building is a sure-fire hit!
