River Otters, land or water animals?
River Otters or Lutra canadensis

![]()
Adult, Male North American River Otter
Available on Allposters
The river otter is a land mammal that spends a good deal of its time in the water. River otters are adapted to fishing in the cold waters of North America with their webbed feet and thick layer of insulating fat.. Their thick dense fur also helps to insulate them from the cold water. River otters may measure as much as 125 centimeters long and weigh up to 11 kilograms.
River Otters can be living in the woodlands of Canada and the United States. Look for river otter tracks along frozen stream beds in the winter. Where ever they can find holes in the ice river otters may be hunting for fish, freshwater clams and other aquatic animals.
River otters often take up residence in abandoned muskrat dens. After mating in February river otters give birth to up to four baby kits in late April. River otter kits may be preyed upon by foxes, wolves and raptors but the adult river otters need only fear loss of habitat and ingestion of pesticides such at DDT which accumulates in their systems because of being at the top of the food chain.
Much of this information comes from Alberta Fish and Wildlife.
How to Make a Tree
Meet Grandfather Tree who tells River Otter Tales
Mrs. Seagraves says,"Meet Grandforest Tree. He lives in our Environmental Center Classroom, and he has many tales to tell. We love to listen to him tell us stories about nature and the environment.
He has a really neat voice. We also like to try to find the different creatures which make their home in and around Grandforest Tree.
If you look carefully, you might find a bat, preying mantis, a 5 lined skink, an opossum, a raccoon, a snail, ants, or a river otter! We like to use the puppets and tell our own stories just like Grandforest Tree."

The Salamander Room is a great read aloud for introducing the River Otter Habitat to your students. A young boy imagines how he could turn his room into the perfect habitat for a salamander.
I made a recording of it and have Grandfather Tree read it to the children.
The Tree House provides a shady Theater for your River Otters
Set up a Computer in the Tree for River Otter Movies

For a simpler version of Grandfather Tree try buying one or making one from a refrigerator box. There are great videos on Youtube showing how river otters swim, dive, slide and play that you could set up to play on a computer set in a hallow hole behind a panel in Grandfather Tree's trunk..
The Interactive River Otter Bulletin Board
Let your little River Otters help to make the scene grow.
1. Start by covering your bulletin board with an old blue sheet (paint it if it's not blue) to resemble a river or pond.
2. Have the kids experiment with blue and yellow paint on large paper at the easel.
3. Once they are dry the kids can cut them out in the shapes of leaves, treetops, bushes, grasses, sedges etc.

Freshwater Habitat Bulletin Board
Available from EduPress
4. Cut index cards to resemble fish and use these for children to record the names of books they have read. (River Otters love to eat fish.)
5. Use the overhead projector to blow up the outline of an otter to it's actual size.
6. Cut out the otter and attach it to the bulletin board with the caption "Fishing for good books to read".
7. An air bubble could be added above each fish for each additional child who has read the book.

7. A blue rug resembling a river might be added to the entrance.
Word Wall in the Tree
River Otter Habitat Word Wall Leaves
As it gets near the ceiling, the branches could continue onto the ceiling along with the leaves and branches along the ceiling above the reading area. Some of the leaves could hang a little further down and have words written on them. Write the same word on each side so that as they move around everyone can still read them. For example these are ideas for animals that could be found up in the tree:

Picture Books for the Otter's Den
Let's learn about River Otters!
Supply the den with a good assortment of picture books such as Playful Slider by Barbara Juster Esbensen and My Little Book of River Otters which tell the life cycle of these playful little creatures. Otters Underwater by Jim Arnosky is written in large print with very few words per page making it ideal for beginning readers.Little Joe Otter and other books in the series bring the woodlands to life with cute little fictional characters. Each chapter is only a page or so long so that they work very well in a classroom setting for story hour.

Two Otters Hunting for a Frog
Available on Allposters
Otters are fish-eating mustelids (related to ferrets) known for rudder-like tails, flipper-like feet, and a silent dive that is always followed by expert swimming of an extremely hydrodynamic mammal.
An otter's eyes and nose are located near the top of its head so that it doesn't have to stick its entire head out of the water to breath or look around, which would attract predators. It's mouth is full of sharp teeth for catching, killing, and ripping up fish, and are also good for opening rock-weakened shells of clams and mussels.
Hotroot Soup, a River Otter Song
This is a song sung by a River Otter a book by Brian Jacques
Hotroot Soup
(A song sung by Folrig the Otter)
When I was just a liddle beast,
I was so small and weak,
I'd often fall flat on me tail,
An' I could 'ardly speak.
I scarce could totter round the the floor, Me whiskers used to droop,
'Til granma made a great big pot
Of good ole 'otroot soup!
An now I'm brisker than a bee,
More fitter than a mole,Most every day I 'ear granma say,
'Give 'im another bowl!'
I'll live a thousand seasons,
Grow strong as any tree,
Give me a spoon an' fetch it soon,
Good 'otroot soup fer me.

WHO WENT WHERE? Otters have scent glands just like skunks and leave their marks around their territory. Just before recess, have two children soak scrapes of cloth in two distinctly different smelling liquids. Then go out to the playground and leave the cloths all around. When the rest of the children go outside, they try to find the cloths and smell them to try to guess which river otter left his/her scent.

RICE TABLE RIVERBED: Put on plastic aprons. Fill the rice or sensory table with mud. Add some plastic otters, and other plastic woodland animals. Scatter some birdseed onto the mud.
The children can create a river bank habitat. They might dramatize interactions between river otters and other animals they might encounter along the river bank. They can pretend to be river otters slipping and sliding down the river bank creating paths or slides down into the river. What fun!
Keep the rice table covered when not in use. Over the weekend the seeds will start to sprout. What a surprise for the children! Let them continue to explore the river bank habitat of the river otters while and discovering the parts of plants.
Encourage the children to keep a journal of their observations. Including interactions between river otters and encounters with other animals, river otters and the river bank as well as observations of plant growth.

HANDWRITING and SPELLING PRACTICE: Otters live in areas with birch trees. If you can find fallen birch trees it can be fun to write on the bark with pens. (Don't strip the bark from live trees as it will kill them.)
Otters also leave their tracks in the mud so your little otters might like writing in the mud outside, on a cookie tray covered with mud or sand, or painting their words with water outside on the playground.When picking spelling words, have each child look in their journals for words that they are having difficulty remembering how to write.
They should practice these words during the week and take a test with a partner at the end of the week. Write misspelled words in their Personal Office.

River otters love to slip and slide down waterfalls like this one in Franconia Notch State Park.
Recently we visited the river otter exhibit at the Miami Metro Zoo and watched the river otters as the dipped and dived in the man made river. They chased eachother up the bank and plunged down the waterfall. It is rare to see river otters in the wild so try to take a field trip to a zoo where you can watch them up close. Be sure to come back and tell us about all that you observed.

PLANTS: Ask parents to donate lots of healthy plants. Have the children start some plants from seeds. Try growing birdseed in the rice table or in a dishpan. Sweet potatoes grow quickly into long vines and eventually have white flowers. Go on a field trip to a riverbank or pond where you are allowed to collect samples and take back some plants. Pussy Willows grow easily from cuttings. Other plants may need to be dug up and transplanted.
Allow children to choose the plants and animals that they would like to care for and have them record their observations daily.

River Otter Math
Measure, count, populate and and get wet while learning math.

Part of our River Otter Unit Study involves studying the river otter's habitat. River otters live on the banks of rivers and streams. The volume of running water is vital to their survival. For math class we will be learning how to measure water. Being a liquid, water is measured by volume. You can also measure how deep the water is as well as how fast the water flows. Repeatedly taking these measurements and recording them will give you a new understanding of the stream or river near your home or school. How much water do you think river otters need to survive?
Add water or sand to your rice table with measuring cups. Allow children to discover how many cups in a gallon, teaspoons in a cup. Make flannel cutouts of the measuring cups, gallon jug, and measuring spoons. Make these to size. On a flannel board near the rice table have children record their observations for example putting a gallon jug, equals sign, 4 one-cup measures. Create a Gallon Man but make the face look like a river otter. Later they could record this in their math journals.
How Long is that River Otter?
What do those numbers mean when you read how long an otter is?
1. Use an overhead projector to blow up a picture of an otter until it is the actual size.
2. Have a student trace around the outline, cut it out and mount it.
3. Do this with other similar animals to compare such as lemmings, weasels, mice, rats, etc.
4. An inchworm is hunches up itself in order to move forward about an inch at a time. An otter uses a similar motion.
5. Now that you know the average length of an otter, what nickname could you give it?
How deep is the River?
Is your river deep enough for a river otter?
How much does a River Otter really weigh?
What do those numbers mean when you read how much an otter weighs?
1. Research the weight of an otter. Using bathroom scales a grocery bag, fill the bag until it weighs the same amount as an otter.
2. Record your observations and share the information with the class.
3. Compare this weight with the weight of other simular animals.
4. Try to find other objects in the room that weigh the same amount as an otter.
5. Make a collection of 3 0r 4 objects and have others guess which one weighs the same as the otter.
6. Make this a self-checking exhibit by taping the answer to the bottom of each object.
What temperature is the water?
Can the water get too cold or too hot for River Otters?

TEMPERATURE:
1. Go to a nearby stream or pond and measure the temperature.
2. Without stirring it up, try to measure it at different depths.
3. Go back and measure it on a sunny day compared to a cloudy day.
4. Do it again a month later, after a dry spell or after a rainstorm.
6. Record and share your observations.

Patterns are the basis of all math. Recognizing patterns will help children understand sets, addition and eventuall algebra and geometry.
The Science of River Otters
Cute pictures? You decide!

Children can put on plays reenacting the information they have been learning throughout this river otter unit study.
River Games
Gather all your Little River Otters and learn how the water flows.

All the little otters in my class love to go fishing while working on math skills. Each player has a recording sheet and pencil. The number on the fish represents the number caught.
1. Catch 2 fish.
2. Write and add up the number caught.
ie: 3 + 2 = 5
Note: As their ability to add progresses you could increase the number values of the objects to be fished by writing numbers on the Chart instead of using the numbers provided by the game.
Once they understand place value, the first fish could represent the tens column and the second fish the ones column. In this case you could have the children catch 4 fish for each turn to add 2 digit numbers.

Pick your best paintings and make them into a book describing the techniques you used. Make a series of pictures, add otters and tell their story. Or paint pictures that show what an otter sees as it swims through the water. Turn a refrigerator box into an art gallery and mount your paintings. Don't forget to mount them and give them titles. The above painting can be found in the link titled "Riverbank Painting" below.
River Otter Songs and Chants
River Otter Music

OTTER SONGS: Change the words to familiar tunes to reinforce what you have been learning. Print these new songs on large poster paper, laminate them and hang them near the calendar. (See Reading Outside the Den above) for example "Ten Little Indians" can be changed to "Ten Little Otters".
"Row, Row, Row Your Boat" fits the theme fine but maybe your could add other verses for example:

HAPPY OTTERS by Evelyn Saenz
Slide, slide, little otters
Into the water deep.
Swim around and look around
And find some fish to eat.
Swim, swim little otters
Swim along with me.
Around the rocks and under the logs
We're happy to be free.
Here's another Otter Song to the tune of "Are You Sleeping":
OTTER SONG by Evelyn Saenz
We are otters.
We are weasels,
In our den
On the bank.
We live in the forest,
Right beside the water.
Jump right in!
Come and swim.

Have you ever had a song repeat over and over in your head? To learn anything you must practice over and over. Repetition can be fun when it is disguised in a cheery tune. Change the words to a familiar song and soon the concepts you are teaching will be running through the children's heads day and night.
- Sing to learn Kindergarten Science
- Educational music so catchy kids will listen to it over and over again, all the while learning basic concepts in science.
- Otter Song

Little Joe Otter's Literacy Bag

I Otter Be Reading by Otterthings
Available on Zazzle
This would make a great Take Home Story Bag. Just add a couple of Books about River Otters, a stuffed River Otter, a game, and a journal for recording their experiences and you have the perfect homework assignment.
Children leave a story in the journal about the adventures that Little Joe Otter had when visiting their house. The next child to take home the River Otter Bag gets to read all of Little Joe Otter's previous adventures.

Fauna in the River Otter Habitat
River Otters live on the banks of rivers. They often slide down the banks into the rivers. Sometimes it seems they slide for fun and at other times they may slide into the river to catch fish, crayfish and other aquatic dwellers. Along the bank river otters may encounter musk rats, amphibians, deer, and many kinds of birds.
