Lemmings
WHAT ARE LEMMINGS?Lemmings are chubby little rodents that look like mice. But they aren't. Lemmings are more closely related to voles and muskrats than mice. They have thick fur that helps to keep them warm. They have short legs, tiny ears, a tiny tail and little black eyes that might remind you of hamsters.
Lemmings are four to five inches long. In the summer their thick fur is grayish or brownish on their backs with pale yellow fur on their stomachs. They have short tails and ears which are so small that they are almost hidden by fur. They have strong legs and claws for digging.
WHERE DO LEMMINGS LIVE?Lemmings live in the open tundra in tunnels they make under the snow or just under the ground in Alaska, northern Canada, Scandinavia and Siberia. Their underground burrows have rest areas, bathrooms and nesting rooms.
Lemmings make nests out of grasses, feathers and musk ox wool.
Lemmings are basically shy. But they can be very aggressive and even courageous when cornered. Lemmings have even been known to attack 1,000-pound polar bears when cornered.
Lemming Population
ARE LEMMINGS ENDANGERED?No! A female lemming can have up to seven litters a year with about 11 babies in each litter. There are generally more females than males in each litter. Females become adults and mate in only 30 days. That means one female can produce thousands of descendants in a single year. The high number of lemmings helps to provide food for many animals.
DON'T THINGS GET CROWDED?Yes! As their numbers increase, lemmings get cranky. They fight in burrows and tunnels beneath the snow.
Finally, thousands will leave in search of a new lemming-land. Imagine there being 10 times as many people in your house; you might want to move too.
WHAT HAPPENS?Some find nice, new homes. Lemmings are good swimmers, but many drown trying to cross rivers and lakes. Some lemmings get eaten by trout. Others move to places where there's little food and starve. Lemmings are sometimes seen on sea ice well beyond land and probably drown. In some places, great swarms of lemmings have moved over wide areas of land to the sea, then plunge off cliffs and drown. But it's not animal suicide. The mass deaths are accidental.
HOW OFTEN DOES THIS HAPPEN?
Life gets too crowded for lemmings about every three to four years.
Understanding the Lemming Exodus

The need for the Lemmings to leave their home and look for new territory reminds me of the Logical Journey of the Zoombinis. It is based on the story of a large group of small creatures moving into a new territory. Children can learn logical thinking and strategy skills from this program.
Another related resource is the Wump World by Bill Pete where over crowding causes the Pollutions to invade the Wump's World. Wumps also resemble lemmings. The Pollutions resemble humans.
Lemmings - Tell their Story!
Students need to write alot and often in all areas of the curriculum.
WRITE AND SHARE: Write about your lemming research every day and share this writing. Publish the best stories and put them in the library or Reading Nest. Have blank books available as well as lots of paper and writing tools in the writing center.Write books as a whole class. If you made an ABC book about lemmings each child could write and illustrate a page. Ideas for each letter could be brainstormed during circle time.
Write number books 0-10 items on each page. Or write Math Word Problems on index cards and incorporate them into a Lemming Trivial Pursuit Game.

Make your classroom reflect the Arctic Tundra where the lemmings live. Sky level (ceiling or near ceiling) could reflect the wide open expanses with maybe a few small birds flying overhead. At eye level there could be low rolling hills and a few willow and birch trees. At ground level there could be mosses, lichen, rocks, grasses and sedges. Use this atmosphere to begin settings for stories about lemmings and their habits.
If you have access to fallen birch logs, it is fun to write on birch bark. (Don't strip it off the trees as this will kill the trees.)
Start a Word Wall of words that the students need help spelling. Ask the children for suggestions, have them put the words up in ABC order. Review them often. Use a willow stick or fly swatter to point to the words. One of the centers could be "Write the Wall" where they list favorite words found around the room.
Mini Offices are three sided folders with a picture dictionary of themed words on the left, pictures in the center and a Word Wall of Dolch List words or words that this student is learning to spell on the right.
Use these new words to teach phonics. The word lemming, for example, starts with the CVC syllable lem. Since that syllable has a short e you must double the consonant to add the -ing.
Write fiction, non-fiction, poetry, posters, notes, lists, etc. about lemmings. Keep writing all the time.
For more ideas on teaching reading check out Beginning to Read.
Lemming Predators
Lemmings are eaten by many animals. The ermine (weasel), Arctic fox, Snowy Owl, wolf and wolverine are just some of their enemies.


Arctic foxes can sniff out lemmings in their burrows under the snow.

Ermine (weasels) can fit down the lemmings' burrows. They chase the lemmings into their burrows and kill them by biting their necks.

When there are fewer lemmings, there are fewer predators (animals that hunt lemmings for food). High numbers of lemmings help to provide food for many animals.
HOW DO LEMMINGS PROTECT THEMSELVES? Lemmings run quickly and hide in their tunnels under the snow or underground.
IMPORTANT FACTSThe number of young that a Snowy Owl has depends on whether there are a lot of lemmings or not.
Predators
Students can act out their newly acquired knowledge of the predator/prey relationships in the dramatic play center. Put out a few stuffed lemmings and predators such as owls, foxes, wolverines, and wolves. At the end of Center Time you might have the group act out their scene for the rest of the class.
Lemmings Live in Tunnels

Lemmings make tunnels just below the ground surface.

Lemming Tunneling through the Snow
Classroom Habitat
Open spaces with lots of tunnels
CLASSROOM HABITAT: Lemmings live in tunnels on the open tundra.
To make your classroom feel like a lemming's habitat. Provide lots of tunnels between learning centers.
In my classroom I have several low bookshelves. I separated them and make a tunnel in the space between them to allow the children to pass between centers.
The Myth of Lemming Suicide

- Lemmings, dying on camera
- Dr Beetle discusses the origins of the myth of lemming suicide, started by the Walt Disney nature documentary 'White Wilderness'
Lemming Suicide
Did it surprise you that lemmings don't really commit suicide?
Fetching blurbs now... please stand byYes, I thought they all had a death wish.
chefkeem says:
I had only limited knowledge of lemmings, although I'd heard of the "mass suicides" myth. Now, I know it's a myth and I know a lot more than that about them lemming rascals.
Posted March 30, 2008
No, that's preposterous!
HeartMagic says:
I didn't even know what a Lemming was til now. It would appear that attacking a Polar Bear would seem a bit suicidal for such a wee little creature.

The Reading Nest
How to make Milk Carton Igloos
MAKE A READING NOOK:To make ain igloo collect lots of milk cartons and make sure that they are throughly washed out and dried. Ask the whole school to collect them for you as you will need at least 160. Use hotglue to hold them together. Start with a nearly complete circle of about 25 jugs and a yardstick to hold them in the shape of a circle. Glue the yardstick at the entrance.
Add four or more rows on the top decreasing the number slightly with each row. Now add another yardstick for the top of the doorway. Then decrease rapidly to form the dome.
A good reading nest should be covered on the inside with grass-colored towels or cloth, and have a light fixed into the roof's top.
Pillows should be set up for students to lean on while reading. They can also be covered in grass-colored towels.
For a lemming-nesty effect, add stuffed lemmings to cuddle with or interact with.
Also add a stack of books about lemmings. See the list below for suggested titles.
Summer and Winter

We made this igloo after seeing it on Mrs. Flannigan's page www.littlegiraffes.com but we didn't stop there.We added rope lights to make it easier to read and then the blankets and pillows to make a cozy nest.
We had a couple of fluffy white bathrobes for those who wanted to be winter lemmings.
Later we covered the whole thing in brown blankets and added brown bathrobes for the summer lemmings.
Later this became the River Otter's Den, a bird blind, and the mud at the bottom of the pond where the frogs go in winter.

To hear a real rodent sing check out my Whitefoot the Woodmouse lens. Down towards the bottom you will find a recording of a mouse that in fact sings.
Lemming Math
How do those cute little rodents measure up?
Lemmings are small rodents.They eat plants, weigh between an ounce and four ounces and are three to five inches long.
They look rather like hamsters, and may be brownish or dark gray in the summer, when they live in tunnels in the ground.
They have short tails and fur on their foot pads to help them to keep warm.
In winter lemming fur turns white, and the little creatures make tunnels under the snow and eat the plants that they find.
The lemmings use the reproductive strategy, breeding very rapidly, hoping that some members of their group can survive despite predators and difficult weather conditions.
After a 20 day pregnancy the mothers produce litters of 6 to 9 babies, and the mothers soon become pregnant again. A lemming can have 3 litters a year.
More than half of the new lemmings are female, and when they are a month old they can also become pregnant.
Like J.J. is doing in his classroom. Weigh the container first without the mouse.
Then add the mouse. Weigh the container with the mouse.
Then subtract the weight of the container from the weight of the container with the mouse to find out the weight of the mouse.
Does the mouse in your class weigh more or less than a lemming?
2.Take a picture of a lemming and blow it up to the size of a real lemming.
Or make a game of it and have several sizes and have the children guess which one is the correct size.
3.Try walking on a tile floor barefoot compared to with socks on pretending to be lemmings. How does having fur on the bottom of their feet help them?
4.Make some brown lemmings and some white lemmings. Place them on white snow and on brown tundra to see camouflage.
5. Use the bar graph
form to display results of a survey about favorite arctic animals.
6. Subtraction: Fill empty white Cottage Cheese containers (Snow Covered Hills) with 12 cotton balls each (Lemmings),2 dice and a worksheet that reads "12 Lemmings. __ jump off. __ left." repeated about 10 times.
Student places all 12 lemmings on top of the cliff, rolls the dice to see how many jump and records the answers on the worksheet.
7. Multiplication of 4's: Use a four legged plastic animal with paw print stamps on it's feet (Pretend that it's a lemming.), 2 dice, and a worksheet. Students roll the dice.
Use the stamp that many times and record the answer. All problems will start with 4 X __ = __ . For younger children, have them first put markers(lemmings on every 4th number on the number line up to 48 and allow them to do the work near the number line.
This part could be done during circle time and the worksheets could be done in pairs or small groups.
8. Graph daylight hours over the course of a year. Does this relate to the giant vegetables grown in Alaska?

9. Graph average rainfall/ snowfall and temperature.
There are lots more games that can be adapted to learning about lemmings at Fun Educational Games
Understand the Math behind the Lemming Population Explosion
Math Books

Read One Grain Of Rice: A Mathematical Folktale by Demi Using a calendar and small stickers show how the lemming population can increase over several months.
Lemming Science

Did you know that if it gets cold enough that bubbles will freeze? Lemmings live in a climate that cold. If your class is in a northern climate you might try going outside on a very, very cold day and try blowing bubbles. They freeze in the air and can shatter like glass when they fall to the ground.

Tundra Habitat
Make your own Moss Garden and populate it with lots of lemmings.

You can easily make a Moss Garden by collecting moss, placing it on dirt in an old pan or terracotta dish. Add a few other plants and spray regularly. Add water to keep it moist. This moss garden grows well away from light.
We add a couple of plastic mice that we pretend are lemmings. The children like to use their growing knowlege of lemmings and their environment to act out the lives of these cute little rodents.

Lemmings in the News!

- Arctic Meltdown Opens Fabled Northwest Passage
- A fabled sea route above North America linking the Pacific and Atlantic Oceans has become a reality thanks to global warming.
Scientists have confirmed that in August, Arctic sea ice shrank to its lowest levels since satellite measurements began monitoring the region nearly 30 years ago. One consequence of this is that the Northwest Passage has opened up much earlier than expected.
Follow the Leader Game
Pretend to be Lemmings

Follow the Leader (game)
First a leader or "head of the line" is chosen, then the children all line up behind the leader. The leader then moves around and all the children have to mimic the leader's actions. Any players who mess up or do not do what the leader does are out of the game. The last person standing other than the leader is now the new leader.

A Lapbook is commonly prepared using a file-folder, folded in a "shutter-fold" with a display of bookslets and other information from a study. A Lapbook displays the highlights of the study. It is used for display of information from a study and as a tool for reviewing material as the child comes back to look at the Lapbook.
The Writing Process
IlluStory Make Your Own Story Kit

Most educators now use the Writing Process to teach children how to write.Children learn to write by focusing on the process of creating writing rather than the end product.
When writing, students utilize the stages of the writing process which include prewriting, drafting, revising, editing, and publishing.Prewriting is the planning and idea-gathering stage.
Drafting refers to time spent composing a rough draft.Revising is the process of improving the draft.
Students reread their work and share it with a partner or small group; they then make changes in the writing based on the feedback from their peers.
Editing is the process of correcting mechanical errors.Publishing is done when the work is in final form and ready to be shared.(Information gathered from North Central Regional Educational Laboratory)
Once the children have taken a story through these stages they are ready for publishing and "IlluStory " makes publishing simple.
To publish the child simply uses the markers and special book pages included in the kit or the book can be made entirely online using Internet drawing and writing tools.
The completed story pages are mailed in the postage paid envelope provided. In just a few short weeks you'll receive back a professionally typeset, hardbound book even includes a title, dedication page and "About the Author" biography page to give it a truly professional touch, ready to display in your classroom library and sturdy enough for the school library.
At the end of the year parents will want it to proudly display on their coffee tables.
IlluStory is a multi-award winning activity kit and perennial best seller because few products, if any, can build as much self esteem and excitement for reading and writing.
The quality of the finished book is a tremendous value and rewards any level of effort.
Extra books can be ordered and are the ultimate gift for family and friends, especially since each can be separately dedicated to the recipient. Ages 5 and up.

Blogging about Word Walls and Lemmings

The other day I was writing about Word Walls and realized that they aren't just for teachers of small children. They are an excellent tool for learning ESL or any foreign language.
Word Walls are words that are groups of words posted in a convient place in order to practice remembering their meaning or spelling. I have used Word Walls to help first graders remember the Dolch List words, spelling words and words related to certain themes. I have used Word Walls in the bathroom with my children to help them learn new vocabulary when we were homeschooling or learning Spanish, Italian or French.
When we were learning about lemmings (They don't really jump off cliffs you know.) We covered a wall with blue and white for an arctic scene, added bits of moss and lichen and a tunnel with a few cute little lemmings scurrying around. Then I asked the children for words to label the wall.
lemming, snow, sky, lichen, tunnel, snowy owl,
We next made a Word Wall of verbs to discribe the lemming's movements. I wrote the words on cutouts of lifesized paper cutouts of lemmings and attached them to the brown tunnels below the snow. By writing the verbs on the lemmings I hoped to convey that these are words that discribe movement.
I attached the lemming words with pushpins so that the children could take them to where they were writing and then easily replace them when finished.
If you would like more ideas about Word Wall please to to Beginning Readers.
The Ideal Lemming Classroom Habitat
The best area for studying lemmings.
CLASSROOM HABITAT: The ideal classroom habitat for studying lemmings would be a class room with light-colored walls, because lemmings live in the arctic. Stuffed lemmings are also a good idea, as they encourage the students to study the body parts of these rodents. The classroom should be decorated with willows and dwarf birches, which lemmings eat the bark off during the winter. A "reading nest" should be set up for the students to read in. See Stuffed Plush Norwegian Lemmings in the links list. Teaching Books to Expand your Knowledge of the Lemming's Habitat

These books have lots more theme related activities to keep your little lemming busily learning all day.
